Floydieguns Posted May 21, 2018 Report Share Posted May 21, 2018 (edited) Well, the USAS 12 is pretty stiff for a regular joe.. the costs, licenses.. I have seen a little bit about the utas xtr 12. Some people claim dpms308 will interchange with upper/lower swap. Anyone know much about these? Looks like a large-frame lower could be made to work with the fr98/fr99/br99/mka 1919 magazines.. has someone else here explored working an upper into holding one of these? With a saami spec of 11,500 psi.. even more low than a 45acp.. i imagine the 308 bolt carrier could support a very thin bolt/lug profile. However, I have none of the xtr parts at hand to compare. A little curiosity struck. Edited May 21, 2018 by Floydieguns Quote Link to comment Share on other sites More sharing options...

Floydieguns Posted May 21, 2018 Author Report Share Posted May 21, 2018 No. It was a youtube video. Poorly done, by likely a very unexperienced owner. The thumbnail was of the receivers split, on a bench. A review for the model type. Smallville will ar10 shotgun/ar12 search phrases. 18minute video. A few other people are claiming 'combination gun'. Wish I knew more about it. The usas12 sure looks better though. Wish somehow that could be brought back as a sporting shotgun, a3 top and offer t-rails to screw on akin to magpul delta ring handguard. Was curious if anyone knew much about the ar style shotguns. For a multi-gun perspective. Those box magazines make for better weight bias and selection between slug/shot. Quote Link to comment Share on other sites More sharing options...
mrmackc Posted May 21, 2018 Report Share Posted May 21, 2018 I really don't see how the Remington 1100 or Ithaca 51 action with a detachable mag or the original tube be bested without a bunch of investment cash. (why re-invent the wheel?) Quote Link to comment Share on other sites More sharing options...
guruofhotrod Posted May 21, 2018 Report Share Posted May 21, 2018 There is a thread on 12GA AR Uppers here: The WF Armory links I posted are now dead but this one from Tombstone Tactical for the Intrepid upper is good https://www.tombstonetactical.com/catalog/intrepid-tactical/143001-ar-10-complete-upper-receiver-12-ga-18in-5rd-black/ Quote Link to comment Share on other sites More sharing options...
Robocop1051 Posted May 21, 2018 Report Share Posted May 21, 2018 I have some first hand experience with the XTR and it is all positive. 1. Most important... it eats everything! From Walmart bird shot to duty buckshot. It all went bang. I did not try any legitimate “low recoiled 2. It is a standard LR-308 lower receiver. The buffer weighs about one ounce and the buffer spring is only about half the normal length. Swap the recoil assembly and you can fit a LR308 compatible upper on there. 3. It is deceptively lightweight. The biggest weight loss being the standard shotgun barrel. I’ve heard rumor that people have sent their barrels in for internal threads and added some screw-in choke tubes. Making a 00 buckshot pattern at 50 yards with an Extr Full choke would be badass. 4. The 8 round mag is all steel construction and about the size of a LR25 mag. It weighs a ton, especially when loaded up with defensive loads.

Robocop1051 Posted May 21, 2018 Report Share Posted May 21, 2018 Waiting for some entrepreneur to use a SB Brace, cut the XTR barrel, and make us a “firearm”. Quote Link to comment Share on other sites More sharing options...
Floydieguns Posted May 21, 2018 Author Report Share Posted May 21, 2018 Really, only a one ounce weight and a 223 lightweight action spring? Robocop, will you post some pictures of this bolt and barrel extension? The shotgun barrel will be very lightweight when compared to a 308barrel. Being proofed for less than 25,000psi and such a large inner diameter.. Only eight rounds? I have already seen people making magazine extensions for ten or more. Multigun performance shops. It is the standard inner diameter of upper receiver as a dpms/sr25? Anything different about the carrier or buffer length? Quote Link to comment Share on other sites More sharing options...
Floydieguns Posted May 21, 2018 Author Report Share Posted May 21, 2018 **failed to edit** Is the xtr12 upper the same inner diameter as a dpms/sr25 standard? Bolt carrier and buffer lengths also 'generic'/'standard'? Thank you Quote Link to comment Share on other sites More sharing options...

98Z5V Posted May 21, 2018 Report Share Posted May 21, 2018 Had a MKA-1919 demo gun out in the dirt a couple weekends ago. Ate everything we fed it, and shoots incredibly smooth. Quote Link to comment Share on other sites More sharing options...

I don’t own the shotgun myself. It belongs to my friend. I will set up a date to hang out with him soon, but it’s going to be at least a week before I can post pictures. My schedule is packed for the next 6–7 daysI will set up a date to hang out with him soon, but it’s going to be at least a week before I can post pictures.
