I popped into Silencer Shop to see what was good and new, and they suggested I borrow a Griffin Armament AR-15 for review. Wait, Griffin is making complete guns? Considering their solid reputation for components like bolt carrier groups, barrels, charging handles, muzzle devices, and more, putting together a complete AR was an obvious next step. And you know what? They’re really good guns.
But did I want to borrow a .223 Wylde or 300 Blackout? Yes!
Griffin makes nine different AR-15 variants in both rifle and pistol flavor; pistols in different lengths with different brace options. Each one is a very complete, ready-to-run gun with flip-up sights, RailShield panels, suppressor-ready muzzle device, sling, and more.
Effectively every component on the gun is made by Griffin Armament and most are unique to the Griffin brand.
Their Micro Modular Sights are quite nice. All steel, minimalist, in a flip-up design. They’re compact, sleek, and perfectly functional with a rear peep and front post.
Both are windage adjustable. The front post is also adjustable for elevation.
Both pistols I borrowed — an 11.5-inch .223 Wylde and a 9.5-inch 300 Blackout — were equipped with an SB Tactical SBA3 brace out back. These are installed on Griffin Armament’s own Maritime Receiver Extension with Griffin’s Contour Connect QD End Plate.
Handguard length is nicely matched to barrel length, with the barrel shoulder only just proud of the front of the handguard.
Attached to the M-LOK slots on the handguards are Griffin RailShield panels. The bottom panel is complete with a hand / barrier stop. On either side of the barrel nut area is an integrated QD socket.
The mil-spec lower receiver sports Griffin’s ambidextrous safety selector, A3 grip, and enhanced trigger guard. Perhaps the only not-upgraded components are the magazine release and bolt catch.
Including the trigger. While it looks like a standard “parts kit” job and Griffin doesn’t make mention of it on their product pages, it has clearly received some level of upgrade treatment. At least a polish job. It’s far lighter and crisper than mil-spec.
My only gripe about the MK1, and it applies to both samples I borrowed, is a difference in anodizing tone on the upper receiver. Handguard, lower receiver, and other aluminum components matched quite flawlessly with a deep black tone, but the uppers have a grayer, drier look. It’s possible a WD-40 bath would cure this, but as these guns shipped from Griffin the finish difference was apparent.
Silencer Shop or Griffin Armament must have had the 300 Blackout in a trade show, as there was no firing pin in its Griffin Enhanced Mil-Spec BCG. For testing, I just swapped the .223’s BCG back and forth between the two guns. As you’d expect, this caused zero issues.
Griffin’s BCGs are really nice, made with high-end steels, Melonite finished, properly staked, fully inspected, and all the other good stuff you’d hope for. They have a very solid reputation in the market, and seemingly for good reason.
As you’d also expect, the Griffin Armament MK1s are designed to be run suppressed. From the Primo Gas Block to the Suppressor Normalized Ambi Charging Handle to the Suppressor Optimized Buffer, the end result is a gas-free shooting experience and a gun that doesn’t beat itself up when suppressed.
I slapped a Griffin Armament EXPLORR on each pistol and got to shooting.
First, I was shocked how quiet both of these guns were. Suppressed ARs — especially in 5.56 — aren’t my favorite thing; they tend to be loud with plenty of port pop and action noise. Even suppressed I often shoot them with a plug in at least my right ear. In the case of both of these Griffins I found them entirely comfortable to shoot without hearing protection.
Now, I don’t know what they meter at near the shooter’s ear with an EXPLORR attached, but I can say for darn sure that these guns were quieter for me, the shooter, than any standard AR with a can slapped on the front. With the gas tuning, the receiver-sealing charging handle, and the suppressor-optimized buffer they’re clearly sending more noise out the muzzle and less out the shooter’s side than normal.
Gas around the face was also greatly reduced. Not eliminated entirely, but damn close with no jets of gas whatsoever out through the charging handle area. A left-handed shooter would still find gas from the ejection port bothersome, but for a correct-handed shooter I caught nothing more than the rare puff I could smell, but wasn’t bothered by. Nothing at all like a standard AR squirting high-pressure jets of gas right into one’s eyes.
With the Griffin 416R barrels and the good triggers, I was shooting both of the MK1s accurately while out on the range, but couldn’t properly test them for groups. So, heading to The Range at Austin I sat down at 100 yards with an EOTech VUDU 5-25x scope.
With supersonic ammo from Hornady (top) and subsonic from Armscor (bottom), the 9.5-inch 300 Blackout put up some seriously impressive groups. Awesome results for any 300 BLK of any sort.
Then the .223 repeated the trick, putting a handful of different loads from Armscor, Federal, and Hornady into tight little 5-round groups.
With the dust cleared, I’m left extremely impressed with these Griffin Armament MK1 black rifles. Pistols. They’re properly optimized to run suppressed, they’re accurate, they’re high quality, and they ship complete and ready-to-rock. At an MSRP of $1,895 they most certainly are not inexpensive, but for the buyer looking for a high-end, turnkey gun — especially one to run suppressed — you can’t go wrong with these bad boys.

Ratings (out of five stars):
Style and Appearance * * *
These are good looking ARs, but they don’t particularly stand out aside from the included RailShield handguard panels and the mis-matched upper and lower receiver anodizing.
Reliability * * * * *
I didn’t torture test them, but both of these pistols ran smoothly and confidently throughout a full test protocol all while sharing a single BCG. I shot them suppressed for all but one magazine each (yes, they ran fine unsuppressed as well), and the 300 BLK cycled everything I put through it — multiple brands and weights each of subsonic and supersonic ammo — with no tinkering required.
Ergonomics * * * *
The free float handguard with those RailShield panels and the Griffin A3 pistol grip bump the MK1 up a strong star over your standard, mil-spec AR-15.
Customize This * * * * *
It’s an AR; the customization options are endless. And, from Griffin, you get your choice of muzzle devices and can order the furniture in black, FDE, OD Green, or grey.
Accuracy * * * * *
About as solid as you’ll find for an AR pistol designed for hard use. The 300 Blackout was particularly impressive.
Overall * * * *
Griffin Armament’s MK1 AR-15 pistols get an extremely strong four-star rating from me. At a lower price point I’d give them five stars all day long without question. As-is, I don’t think the price is unfair or too high, necessarily, for everything that you get with these complete packages and for the high level of quality, but they’re definitely priced toward the high end. For the customer looking for a turn-key, everything-included AR in .223 or 300 BLK that will serve them well and run as smoothly, quietly, and nicely as anything on the market whether suppressed or not, the Griffin Armament MK1 series is an absolute must-look.
So would you install a Kali Key or a LANTAC BCG in this if you lived in one of the less free states or one like Fla which could go either way?
As for Florida, even if I owned an AR (yeah, that’s gonna happen) the answer would be no. I own a few of what would fall under the left’s guidelines for a ban. Wouldn’t alter them even if I could. Won’t sell them “back” to the government. I will not comply.
Looking at mine, as far as the possible ban ( I hope it fails !! ) it looks like the 2 Ar15’s possibly the 10-22’s ( can accept larger mags ) and the P226 may be a problem. The others are all 10 rounds or under and no one sells larger mags for them so they should not be an issue.
I just looked at the previous posting and the Kali key seems like it would not fly since it is easily reversible.
Maybe welding the gas hole closed and such would work? Not sure what is special about the Lantec BCG unless it disables the gas system.
The pistol above looks nice but wow the price! Guess I should not have retired.
“ Handguard length is nicely matched to barrel length, with the barrel shoulder only just proud of the front of the handguard.”
Help me here. What does “just proud” mean?” Sorry, I’m a boomer and don’t get trendy references.
I’m a boomer too, Here ya go.
Proud means that the feature is raised from the surrounding surface. You have can have one of three conditions proud, flush and recessed
The 300 Blk used in the vid would be no problem as to any ban as it had no bolt installed from the manufacturer,just a empty carrier,display model ? .
When he swapped in the BCG from the 5.56 into it,perhaps it was just his recording set up but firing subs,it wasn’t the quietist sounding 300 blk.
I know you want to hear what it sounds like with no earpro but please dont. Your ears can only take so much damage over time and the damage is cumulative
Young “it won’t happen to me” types do not want to hear from us how their ears will whine constantly with tinnitus. And they will have trouble with conversations in crowded places, little kids and a lot of women due to loss of high frequencies in their hearing.
And how their minds will fill in the blanks when they do not quite hear a conversation, how they need to watch lips as people talk and so forth. It’s not just guns, how many times have you had a car following you on the highway and you can hear the bass. And many restaurants are way to noisy and on and on.
Hard to wait till I get spare money for a .300 blackout but seriously, pick up your brass already.

Hi Jeremy, I came across your post while searching for the user’s manual of my new Griffin Armament MK1 223. The video was very helpful, thank you.
Do you know were I can get a copy of the user’s manual? The Griffin website does not have one available. So far, I have not got a response from Griffin. Thank you.
