Shooters are seeing a lot of factory-threaded barrels that accept sound suppressors and other muzzle devices, and rimfire rifles, such as the Savage MKII FV-SR Threaded Barrel 22LR, are part of this new supply. In the past, I’ve thought of suppressors as add-ons to my GLOCK 9mm pistol or a Remington .45 ACP 1911, but I’ve learned muzzle mufflers can improve my comfort behind 22LR rifles as well. 

The American-made Savage MKII bolt-action repeater came in a box with a lock and manual. The manual covered the Mark II’s as well as Savage’s Mark I, Rascal, Model 93, B.Mag, and Model 300, Model 305, and Model 310 rifles. The FV-SR looked stubby with a 16.5-inch carbon-steel fluted barrel. Rate of twist was a standard 1:16 inches for .22 Long Rifle.

The diameter of the barrel at the muzzle was 0.870 inch, which suggests the free-floating barrel’s straight contour might make the rifle heavy. But the unloaded weight was just 6 pounds. Also, it wasn’t overly muzzle heavy, with the balance point of the scoped rifle occurring right under the magwell. With a scope and full of ammo, the Savage weighed 7.25 pounds. Its short overall length of 34.75 inches would make it handy to handle going in and out of a vehicle.

The Savage came with an installed Picatinny scope rail, so it was easy to screw on Weaver’s Six Hole Tactical Rings and install a Nikon M-223 series 3-12x42mm (16305) scope. That glass is equipped with a side-focus turret for parallax correction and a one-piece 1-inch main tube that is nitrogen-filled and O-ring-sealed.

Between shots, I could stay on the stock and adjust the scope because the Nikon has target-style knobs with tactile clicks. That makes it easy to dial in wind adjustments on the Nikon, but I rarely needed more than a click left or right of zero because I had 5- to 7-o’clock wind for most of my shooting. 

The bolt-action rifle had a matte-black-finish synthetic stock with a round sporter forend, which rolled on the bags. The straight comb needed more height to allow my face to anchor on the stock, but that will vary by shooter.

The buttstock had a 13.5-inch length of pull. There was a sling-swivel stud at the front to attach a bipod or sling. The neutral butt dimensions, no cast-on or cast-off, worked for both righties and lefties (handedness, not politics). This rifle didn’t have an AccuStock bedding system, but the barrel free-floated nonetheless. Molded-in checkered panels on the wrist and forend offered some texture for a better grip on the stock.

I found the thread protector was easy to remove and install. I liked the big bolt handle because it provided a lot of smooth riding surface to push and pull the action closed and open without grasping the knob itself. The Savage came with one 5-round-capacity single-stack detachable-box magazine with a steel body. I had no misfeeds, and the magazine was easy to seat. I also had no failures to fire or extract. Ejected brass landed near or far at about 4 o’clock, depending on how hard I worked the bolt.

One of the nicer trends in non-competition smallbore rifles is the appearance of adjustable triggers. It wasn’t too many years ago that a small-game rifle like this Savage would have come with a creepy 7-pound trigger. This one came with an adjustable AccuTrigger, and I was happy to tune it.

  • To adjust the AccuTrigger in the Mark II, make sure the firearm is unloaded and the bolt is open before removing the stock and messing with the trigger. Then remove the stock.
  • Insert the AccuTrigger’s supplied tool into the bottom of the trigger return spring to engage the spring-tail with the slot on the tool.
  • Turn the trigger return spring with the trigger adjustment tool.
  • To adjust for a heavier pull, turn the tool clockwise. The maximum trigger pull is at the point where the spring clicks when rotated.
  • Turning the tool counter-clockwise moved me toward a minimum trigger pull. I was happy when I got the pull to 2.4 pounds, and I dropped the rifle on its butt at different angles to ensure that the sear didn’t release.

For bench-accuracy shooting at 50 yards, I fired the rifle off of Caldwell DeadShot shooting bags. Accuracy is the average group size for five five-shot groups, measured center-to-center of the widest-apart bullet holes in each group, then rounded to the nearest tenth of an inch. Suppressed data was collected with a SilencerCo Osprey 45 ($756 at directly after I shot the unsuppressed data for each round.

The SilencerCo Osprey 45 suppressor weighs 11.1 ounces and measures 8 inches in length. To fit the Savage 22 rifle, it requires a 9mm Osprey piston, $71. Both are available from (Woody for TTAG)

The SilencerCo Osprey 45 is an eccentric monocore baffle design with a black-oxide aluminum shell and stainless-steel internals. The Osprey 45 weighs 11.1 ounces and measures 8 inches in length. To fit the Savage 22 rifle, I used a 9mm Osprey piston, $71, also from Silencer Shop in Austin.

Suppressors are generally manufactured with different thread dimensions to make it harder to accidentally fit a too-small suppressor onto a too-large-caliber firearm. I would be giving up some suppression by using a larger-dimension exit hole than necessary, but the Osprey wasn’t out of scale for use on the rifle. Also, I didn’t intend to shoot a lot of rimfire rounds with the Osprey because the can isn’t user serviceable, and smallbore rounds would get it dirty pretty fast.

The Osprey comes with a tool to remove the piston and a user manual. To install the piston in the end attaching to the muzzle, the user slides the piston (a stainless cylinder with spokes on one end) into a spring inside a threaded adapter, which then screws into the suppressor body.

Installation on the rifle was simple: With the magazine out of the rifle and the bolt out of the action, I screwed off the thread protector, then tilted the suppressor-ready muzzle upward and started the Osprey onto the provided muzzle threads.

I removed the bolt and magazine for safety because my front hand could be covered by the muzzle when removing the thread protector and installing the can. Also, with the bolt out of the gun, I could look down the muzzle to ensure the suppressor wasn’t impinging on the bullet path.

My 22 Long Rifle ammo samples included Armscor 36-grain high-velocity ammo, Eley Subsonic 38-grain lead hollow points, and Winchester WINS22LRT M-22 40-grain black copper-plated lead round nose bullets. The Eley’s velocities came in at 1014 fps and 1025 fps unsuppressed/suppressed in the Savage. In the middle were the Winchester M-22’s speeds at 1172 fps unsuppressed and 1179 fps suppressed.

The Armscor’s velocities were 1238 fps/1261 fps unsuppressed/suppressed in the Savage Mark II. To collect chronograph and accuracy data, I set up at American Shooting Centers in Houston ( I recorded velocities using a Competitive Edge Dynamics M2 Chronograph ($219 at, Part No. 399-000-012WB) with the first screen set 10 feet from the muzzle. Velocities were recorded with an air temperature of 90 degrees and 90% humidity, with 10-mph mostly 6 o’clock winds.

With the Osprey installed, I found the rifle’s report to be very quiet with the supersonic rounds, and I really couldn’t hear the subsonic rounds with double hearing protection (plugs and muffs) on. (Other shooters were on the range.) The gun would move slightly, and that was a better cue that it had fired than any sound. 

The Savage shot its best groups with the Eley subsonic hollowpoints, 0.7 inches unsuppressed and 0.5 inches suppressed. With the Armscor 36-grain High-Velocity Hollow Points, the Savage fired 1.1-inch average groups unsuppressed and 1.0-inch groups suppressed. The heavier but still supersonic Winchester M-22 40-grain lead round nose rounds shot unsuppressed average groups of 1.0 inches and suppressed average groups of 0.9 inches.

When kneeling and standing, I could run the 60-degree bolt throw comfortably without having to take my cheek off the stock. The big bolt handle aided this process as well. However, in these other positions, the high scope position atop the rail and rings only allowed a cheek-weld on the gun with the side of my jawbone.

The low comb won’t be high enough for some shooters. (Woody for TTAG)

I would have liked a comb-height adjustment pad like the D&E Cheekeeze stick-on pad ($40 from Brownells, Part No. 946-101-925WB) to rest my face on.

There was a thin plastic buttpad on the Savage. I would have preferred a rubber buttpad to stick better on the shoulder, but many shooters wouldn’t like that. The safety on the Savage Mark II FV-SR is on safe when the button sits fully rearward toward the shooter and a red dot on the right rear of the receiver is covered. This blocks the trigger but does not prevent the bolt from being opened.

In the fire position, the safety button is pushed toward the target, exposing the red dot on the receiver. Everything worked perfectly. Removing the bolt for cleaning, bore-sighting, or safety is simple. With no ammunition in the chamber and the bolt loosely open, I pulled the trigger fully rearward and held it in that position, then slide the bolt out the back of the receiver.

To insert the bolt, with an empty chamber and no magazine in the rifle, I lined up the bolt in the action and pulled trigger rearward, depressing the catch in the action that blocks the bolt. The bolt slid right in.

I liked the feel of the detachable magazine fit and lock, and the steel body of the magazine was rigid. I liked the bolt handle, and the AccuTrigger was excellent. It has a short overall length, which makes it suitable for use with a silencer. The affordability of this Savage rifle makes it a candidate for your wish list.

Other rifles TTAG has looked at in this arena include the CZ 455 Varmint Tacticool Suppressor-Ready Rifle and the Primary Weapons Systems T3 Summit Rifle.

Ratings (out of five stars):

Style and Appearance  * * * 
Utilitarian looks. Stubby lines. Looking good isn’t its role.

Ergonomics  * * * *
Too much drop in the buttstock for some shooting positions. Pretty good balance for a heavyweight barrel.

Accuracy  * * * * *
The FV-SR shoots well with ammo it likes, like any other rimfire. You have to find the best ammo by lot-testing. Hopefully, you’ll find something that shoots well both suppressed and unsuppressed. I liked the Eley Subsonic in this role.

Reliability  * * * * *
Bolt gun. Positive and dependable extraction and ejection. Feeding was accurate, with no bullet marring.

Overall Rating  * * * * 1/2
A lot of gun for the money. The adjustable trigger is a plus. The free-floated barrel is a plus. The easy connectivity for a suppressor is a plus. Having a Pic rail already mounted on the receiver is a plus. I’d prefer this unit over a similar heavy-barrel choice that isn’t threaded at the muzzle.

  1. I’ve been thinking about upgrading my old Savage (prior version without the Accutrigger) with a 4X scope that I’ve had for 15 years, so this is a timely article. I’ll want to compare it to the competition, but I never see articles by some of the others such as Kimber or Cooper.

    My rifle has a distinct preference for Remington Goldens, hates lead bullets.

    • I have a non Accu-Trigger version. I installed a Jard trigger and am very happy with it. It’s less than 2lbs. No creep. Highly recommend it, if they are still making them.
      Off topic a bit, but I also had a machinist buddy turn down a 1:9 twist 10/22 barrel and cut another extractor groove in it. It’s in the Savage action now. It’s a dedicated Aguila SSS 60gr shooter. I never could get those things to run well in the 10/22.

  2. Bought this for my son as his gun/rifle, excellent rifle for the money! A Boyds MKII 93E stock replace makes it even better.

  3. Question- other than getting this for a child to learn the operation of a bolt, why buy this over a 10/22 (or clone)? My 10/22 is just as accurate as any bolt 22 and plenty reliable, useful for more purposes, and a lot more fun.

    • A bolt rifle has slightly greater range with higher velocities. The better and the best rifles have superior accuracy. I’ve hit targets at 250 yards with mine. (2″ x 3′ target. Holdover was immense.) And yes they are great for teaching fundamentals to kids; my son was one who would empty a semiauto as fast as he could pull the trigger. And just because a bolt gun doesn’t shoot as fast doesn’t make it any less fun. But you know, you pick what you want. None of these rifles are going to break the bank.

    • A bolt gun has superior reliability to semiautomatic. If all you are going to use it for is plinking then it won’t make much of a difference but if you want to use it for a survival rifle then the bolt gun is far and away the best choice.

    • One of the basic Ruger 10/22s is not as accurate out-of-the-box as the Savage B22 or Mark II FVSRs. If all you expect is “minute of squirrel”, then a 10/22 is fine. If you are going for accuracy on paper or shooting NRL22 base class, the FVSRs are one of the best for the money.

      For adjusting comb height, I used camp pad and vet tape on both FVSRs.

      When using a suppressor, a bolt action will be more quiet… unless you use a 10/22 single-shot bolt block.

      Don’t get me wrong, a higher-end 10/22 is a wonderful 22 rifle and can be very accurate if setup correctly. I have way too much invested in my 10/22s. But they do not compare favorably to a bolt action without some work.

      If you are going to get a FVSR, I’d suggest spending the extra to get the B series. The reliability of the magazines alone is worth it.

    • “…My 10/22 is just as accurate as any bolt 22 and plenty reliable, useful for more purposes, and a lot more fun…”

      Well, no, it isn’t. When is the last time you hit a seven-x-seven inch target at four hundred yards with any kind of ‘regularity’? I agree with its accuracy to fifty yards. My 10-22 is great as a small game getter up to fifty. Beyond that, not so much, regardless which ammo I feed it. My Savage MKII will shoot circles around any stock 10-22 and some built-ups.

      Reliable? Sure- it’s a Ruger, so no doubt about that. Glad you didn’t say ‘more reliable’, as some have, because it certainly isn’t ‘that’.

      A lot more fun? First, define ‘fun’. As noted, I also have a 10-22 (rather, my son has, but it’s technically ‘mine’), and it’s only fun when I feel a need to spray and pray. When I want to shoot MOA/Tactical, there’s no way I’d grab a stock 10-22.

      Besides, ‘fun’ is like beauty: unto the eye of the beholder.

    • “My 10/22 is just as accurate as any bolt 22..”
      Then you have a unique and extremely valuable 10/22.

    • If you have a 10/22 that is as accurate as any bolt gun then there’s one of a few possible things going on.

      1. There is malfunction between the trigger and the ground that is making all rifles tested shoot poorly enough that they seem alike.

      2. You’ve never actually done an accuracy test of your 10/22, and simply consider minute-of-beer-can at 10 yards to be the pinnacle of rimfire precision, and therefore consider it as accurate as any bolt gun you shot at similar targets at similar distance.

      3. (Least likely) you have a singularly unique 10/22 that Ruger would gladly buy back from you for well into 6 figures in order to reverse engineer whatever the voodoo lady did to it to make it as precise as it is.

  4. I have this exact model. Aside from maybe swapping out the stock (that low comb height is irritating) I wouldn’t change much. The 5 round mags are known for splitting at the backs (I have one that does) but the 10 round versions are solid. With a dedicated 22 suppressor, like My Silencerco Spectre 2, they’re about the same diameter as the barrel and look like a natural extension of the barrel. Excellent trigger!

  5. A very nice rifle. Reminds me of a miniature 700P LTR. I was seriously considering buying one when Ruger came out with the 10/22 takedown model. I bought it instead. Now with Washington law classifying all semi autos assault weapons, I wish I would have bought the Savage.

  6. Suppressor and .22 sound funny together, I guess if your trying not to scare away the other squirrels it works.

    • A supressor on a 22 is valuable if you want to shoot sans ear protection without damaging your hearing or teach someone to shoot who is noise adverse.

  7. I have three savage rifles and all have excellent triggers, are accurate as hell and well made guns. Savage is the best value in rifles, you need to spend a lot more money for anything better.

  8. Had an FV-SR for quite a number of years. Excellent little gun. Very very respectable accuracy. Run it with an TacSol Axiom and Wolf Match Target subs. Love it.

  9. I picked this little rifle up even though I shoot almost exclusively CB Longs and other low velocity and low report rounds around the farm… Even though it is labeled LR ONLY.
    And I found out that there actually is a bolt action 22 that really means it when it says LR Only.
    Does anyone know why this won’t feed 22 CB Longs reliably, or if there is a fix to allow it to do so?
    I have another bolt action 22 Savage that takes the same magazines and it works fine for S, L and LR.

  10. I have this rifle and agree with the points in this review.
    I particularly like your use of 5 round groups for accuracy testing – thank you!
    The “side review” of the Osprey is appreciated as well.
