First Ever Functional Gas Operated Rimfire AR-15 from Franklin Armory

Rimfire AR-15 rifles are nothing new, but they all use a blowback based operating system. This puts tons of stress on the cases, and for some of the more powerful rimfire cartridges it can rupture the cases as they’re being extracted from the gun. Franklin Armory wanted to make a semi-automatic rifle in .17 Winchester Super Magnum, and so they completely redesigned the internal components of an AR-15 to function with the cartridge. Now cases extract under lower pressure, the gun cycles reliably, and you can use all standard AR-15 components for stocks and triggers. Naturally, we’ll test one out and get back to you.

Oh, and its pretty. MSRP is gunna run about $1,799, but for serious varmint hunters accept no substitute.

  1. Here’s how you end this: Stage a mugging in some bathroom. You’ll have to bang your head a little so there some blood. Nothing dramatic just some blood for effect. Then tell the police how you left your Springfiels XD 9mm in the car when you went to use the can because of the sign. Then hire yourself a nice ambulance chasing lawyer who’d like to make about 10 million dollars. Then file a suit against whatever agency hung that sign. Sue the state. Sue the guy who screwed in the sign. Sue the security company that was scratching their ass on the other end of the dark 2 acre parking area and wait about a month for the settlement offers to start pouring in. Personally I’d go to trial but if you just want a quick 2-3 million you can settle. Tell them you forget everything now, were severally traumatized, and lost vision in one eye. Make it good! Be careful of surveillance cameras. If there are any just have a buddy act the part of the mugger. Simple! Easy money.

  2. LMAO at the thought that I have access to a national level (or any level for that matter) firearms registry.

    Bet you $5 the cop in this case did what I often do and noticed a CCW license behind the DL when Mr. Filippidis pulled his DL out. The difference is that I say “You have your CCW? Good. Are you carrying today?” and then say “Thanks, just keep it there and we won’t have any problems.”

    Granted, I also have literally said, “Thanks for exercising your 2nd Amendment rights” to a ccw holder on a stop before and I’ve been pro 2nd my whole life.

  3. Does this stuff burn a lot cleaner than .22 LR? I’d certainly hate to maintain a gas system in a .22 LR gun. I have no experience with the fancy rimfire calibers — just .22 LR, short, etc and .22 WMR — so have no clue if it’s still really dirty stuff or is more like a nice centerfire round.

  5. So for only 1000 more than a base ar, you get a less powerful rifle with no real advantages.
    Or you can put the 1000 towards ammo. Just sayin’.

  6. So if I had an AR10 and bought this upper would I need to register the lower as an sbr and an sbs if i wanted to chop the barrel or would I be able to get away with one or the other provided I didn’t have any short barreled uppers for the unregistered caliber?

  7. That is really, really bad ass looking, but the fact that I can never own it in full auto makes it completely, utterly useless and pointless to me. I can think of 3600 better things to do with $3600 than buy that thing.

  8. I was just saying that if you go up against 10 bad guys nothing short of a BAR is going help. I see someone provided a solution to my problem.

  9. I have the Savage bolt in 17wsm. It is a junk stock and I’m hitting prairy dogs at 300 yards. I can only imagine a quality rifle with a free floating bull barrel is going to be a tack driver. No restrictions here but just going to be a great rifle.

  10. Just picked up my HB Savage today.
    Now to get a scope on it and get to sighting it in.

    My new Franklin F.17L should be here late next week or early the week after.
    Gonna be busy!

    Already laid in a pretty good stash of ammo, just lately.
    I think maybe they finally started loading some again.

  11. Still isn’t here!
    Getting anxious!

    But have sighted in the B-mag HB and am impressed, with the cartridge, not so much the gun. Seems to be quite accurate, but factory liquorice stock is junk!

    Boyd replacement stock coming up.

  12. More ammo in the stash today. Two cases, matter of fact!
    And I hear Hornaday is gonna start loading them around the first of the year!
    Yay!

  13. Two more batches of seven boxes each, $14.77 and $15.99 added.
    Coming in faster than being used right at the moment.
    Really impressed with the cartridge, the bolt action Savage, HB, “B-mag”, not so much.
    A Boyd’s replacement stock did wonders for it, though.

    Sure wish the F.17-L would get here!

  14. Finally, it’s here!
    And I am impressed!
    Shorter time to sight in, and first glance seems much more accurate than the HB Savage B Mag heavy barrel. But then, there is that major difference as well.
    From the fired cases, the chamber appears to be much more precisely bored. No smoke leakage, and better case/neck transition.

    Now, shells are not going to last near as long in this thing, got to get back to the hunt for more ammo! It just begs to be shot!

    Had to go to extra high rings to get the 3 X 9 by 50mm scope to work.
    High ones would clear the barrel, but not let me get my face down on the stock far enough to get a full scope picture. When you have a round scope and get a misshapen view, something like a distorted old Burris Wide View image, something is wrong!

  15. Great gun, needless to say, I have been impressed, and absolutely no blips in functioning.
    They got their stuff together before shipping.

    Impressed numerous other folks last Tue as well.
