  1. There are tolerance issues due to barrel diameter inconsistencies. I've seen as much as .080 difference in diameter between barrels. If your barrel is oversized at the point it meets the upper receiver the handguard can fit rather snugly.

     

    Do you recommend we trim down the barrel or open up the handguard?

     

    For us DIY types, open up the handguard might be best.

  2. I'm on the Firebird list for one of their Tac 12 lowers and was wandering if there would be any idea's why I should keep the stock lower after replacing it with the Firebird Lower...and what it might be worth if i decide to let go of it...

    Any thoughts about this anyone?

     

    I'm also on the Tac 12 lower waiting list. I plan on keeping mine so that I can also buy a Firebird upper when they become available.

     

    Then its down to just a few parts to build a second gun possibly on the cheap.

     

    If for no other reason, I'll keep the lower in case a future upgrade requires sending in the Tac 12 lower and I don't want to quit shooting.

  3. I beleive its the mag catch slot, you have to open the top a little more vertically to get it to lock properly

    Thats what I had to do on one of my 10rd mags. Just file a little at a time till it locks.

    Will opening the mag catch slot allow the magazine to sit lower within the magwell and therefore possibly lower than necessary for the bolt to pick up the next round?

     

    If so, trimming the overmold on the magazine or slightly opening the magwell opening might prove better for reliability.

  4. With the "official" Serial Number on the upper, Anubis will not need to change to Anubis-1 on his gun and the rest of us do not need to mess with an FFL to receive the new lower.

     

    It will also make it easier on those sending in their current lowers to Firebird for work.

     

    Good news.

  5. Find someone locally that has one you can try. They sell themselves. The modifications are half the fun. Consider the Firebird 922 compliance version that Centerfire offers. Add a C-more and get after it. That's what I bought.

     

    Now that it is broke in, mine is 100% reliable using 5 rd magazines (all that I have available at the moment) and Remington Gun Club shells (1 oz @ 1200 fsp) for birdshot and Remington Sluggers (1 oz @ 1530 fps).

  6. The 20 rounder looks like two 5 round magazines welded together plus the Saiga 12 round mag and Firebird coupler. Am I close? I assume it runs 100% if its headed to the Nationals.

     

    Are the custom serial numbers available for everyone? I think I'm #23 on the waiting list. It would be a great option.

     

    Very nice setup.

  7. Good evening sir.

     

    In another topic you say "When walking into a big stage, I use 15 or 18 rnd mags...or coupled tens."

     

    You got my curiosity up. Is the 18 round mags you mention for a MKA 1919? If so, is this a one off project or something we will see available from Firebird Precision in the future.

     

    I know of only one other 18 round mag for the MKA. Its handmade by its owner. (A much more talented individual than myself.) I'm hoping to get a look at it someday.

     

    Thanks.

  8. Guess I need to order 12 rounder's now (if i can find them) and sell the 10's to somebody else,,,,,,

     

    I got my couplers in today. They appear nice and solid. At this point, the weakest link appears to be the SGM Saiga magazines. I plan on setting aside some of these should there be problems in the future and the 12rd mags are no longer available. Worst case is the magazines hold up just fine and the spares gather a little dust.

     

    Though the 10 rd Saigas will only give you a 12 rd MKA 1919 mag, you might want to hold onto them.

  9. It seems to work fine when cycling it by hand. I'm sure someone has tried it just want to see if it's safe and if there are any issues firing the 2 3/4 shells out of the 3" magazine.

     

    After initial break in (the only time I've used some heavy 3" shells) everything I shoot is 2-3/4". The two magazines that came with the gun run just fine with those shells. All of the newer magazines are for both size shells and have feed lips with a length between the two.

     

    I may be lucky, but all of my 5 rd magazines run just fine. Next step is convert a few of them to 15 rounders.

  10. looks like a 50 cal next to the others,....nice!

     

    I never really thought about the size difference.

     

    A lot of folks have never heard of MKA 1919 let alone seen one. I went to an IDPA Defensive 3-Gun match put on by some local folks and I overheard a gentleman explaining to his friends I was shooting a bull barrel .308.

     

    Bill

  11. That is pretty much the case, especially in the early runs.

    I believe that problem was addressed and corrected in later batches.

    Anubis will verify that after he reads this

     

    Good thing to watch for. I assume it will be corrected under warranty.

     

    Oh and Shop Monkey, great avatar!

  12. I thought the 5 had to attach to the 12 to make a 15 rounder?

     

    I hope this don't make any trouble, but here is a post from Gentleman Jim on the Enos forum concerning the coupler. Someone questioned if the Saiga 10 rd magazine would make a 13 rnd MKA 1919 magazine.

     

    Bill

     

    "Its an mka 5 rnd attached to a segment of a SF 12 rnd mag, it makes a 15 rnd mag.

    I have never had a 10 rnd sure fire mag, so I dont know.

    Is the Firebird Precision Trigger group assembly considered 922r parts? I just need 3 more parts and I can have my folding stock and my hicap 10 rounds mag.

    Answer is yes. But Firebird does not sell their FCG as a DIY item. You will need to send in your lower for them to install the parts.

     

    It will count as three parts (hammer, disconnector and trigger). My MKA 1919 has these parts and they work great.

     

    Bill

     

    We're going to be selling our FCG as a stand-alone item soon.

     

     

    Anubis what company do you work for?

     

    Anubis works for Firebird Precision so he in in the know.

  15. My local gun shop has a 1919 for $600 I have a siaga 12 but I like the look of these and want one however the one they have is all polymer. The ones on here look like they have a metal lower. Is this a new model or the original with a new lower added on to it? Just seeing if I should buy or wait until I can get a current model? Thanks

     

    My humble opinion, if this is a new gun and you want a MKA 1919, jump on it. The lowest price I've seen on these was at Cheaper Than Dirt last fall at $579. The price quickly went to $619 when they could keep them in stock. Some places indicate they have them in stock starting at $669 and up. If its a used gun, at that price it may have some problems. Pony up the cash and get a new one.

     

    The following information is taken from memory of things I've read on this and other forums.

     

    All of the factory MKA 1919's have the polymer lower receiver. Firebird Precision is in the process of bringing an aluminum lower to the market place.

     

    Did you jot down the serial number?

     

    Firebird indicated the "old" model with serial numbers in the 120XXX to 130XXX range had some improvements over earlier models. Next came some with "XN" in the serial number with what some have said is improved quality control. The latest version actually has "XN" stamped on the upper receiver after "MKA 1919". Per posters on this forum, not all parts interchange between the most recent version and the older versions.

     

    Per Jim at Firebird, there was a batch imported in 2011 that instead of a polished barrel extension, had a black parkerized extension. Lots of problems were seen with this small lot of guns.

     

    My MKA has a serial number in the 100XXX range and runs like a scalded dog. An earlier model that works great. Maybe just luck of the draw.

  16. No does not include the spring. If you have the old style factory Mags you should be alright with the factory spring. If not Carolina shooter supply sells the 10 round spring

     

    I don't see it on their site. I guess its not in stock yet. All my mags are new manufacture so I would need the springs to get the extension to work.

  17. It is a proprietary, patent pending system designed specifically for use with reduced recoil and low pressure ammunition. It is only compatible with the short Firebird handguard. However, that being said, it is a self-install part, but is only available to customers who have purchased handguards directly from Firebird. Until the patent is finalized, there will be no photographs or technical details released.

     

    Whoa, whoa, whoa......Short handguard only???? That is not what Nanci told me. I was told that it wouldn't work with the stock handguard, That it needed the aftermarket handguard. Not a word about a short guard...That would take me out of play.

     

    Its my understanding that the HEOS installed limits you to lighter 12 gauge loads. Something in the 2-3/4" 1200 fps / 1-1/8 oz range.

     

    The short handguard also limits you to 2-3/4" shells. So if you have either on your gun, you need to run light loads.

     

    The long handguard allows running 3" shells. No point in modifying the long handguard to allow the addition of the HEOS. Rather, the design should try to prevent the shooter from running hot loads in a modified gun.

     

    At least that's how I would think it would work.
