98Z5V Posted June 5, 2015 Report Share Posted June 5, 2015 (edited) For a long time now, DDLES - Double Diamond Law Enforcement Supply, in Tucson, AZ - has produced some FINE billet lower receivers for pistol-caliber ARs. These things are very high quality, top-notch machining/construction, and are damn well worth the coin if you're building a pistol-caliber AR. Well, DDLES is now out of that business. I don't know why, but all the designs that they had for those lowers has been sold, or attained, by QuarterCircle10, also in Tucson, AZ. It looks like QuarterCircle10 has expanded the lineup, too. They offer the small-frame Glock mag lower, and also a large-frame Glock mag lower. The still offer the 9mm lower in the Colt/Modified UZI mag lower, too, which is what I have from DDLES. Small-frame calibers include 9mm, .40 S&W, .357 Sig, and the large-frame lowers are 10mm and .45ACP. They have BCGs for 9mm Colt, 9mm Glock cut (it's different than the Colt, so it strips from a Glock mag), .357 Sig BCGs, and 40 S&W BCGs. The .45ACP BCG is listed as "coming soon." No mention of the 10mm yet... For barrels, they have 9mm, .40, and .357 Sig, with the .45ACP barrel listed as "coming soon." Also, no mention of the 10mm yet... They also have spare lower parts listed. These lowers are nice, because the ejector is incorporated into the lower, and it's replaceable, and the feed ramps are replaceable - those parts are roll-pinned into the lower. I suspect that DDLES had these guys making the lowers for them, branded as their own, and the manufacturing company has pulled the design back - marketing them on their own. Just a suspicion, nothing concrete in that at all. Just my $0.02... For $275 for the lower, and them making all the necessary parts in-house (barrels and BCGs), it's really a one-stop-shop for a sweet pistol-caliber AR.

Robocop1051 Posted June 5, 2015 Report Share Posted June 5, 2015 Want cheap fun? Build a 7.62x25! Almost the price of .22lr. Edit: nevermind. I just checked prices, and 9mm is cheaper.... Carry on. Quote Link to comment Share on other sites More sharing options...

suzukiray Posted June 7, 2015 Report Share Posted June 7, 2015 Tom! Those SBRs here in Commiefornia & made from UNOBTANIUM!!! Ray. Quote Link to comment Share on other sites More sharing options...
Robocop1051 Posted June 7, 2015 Report Share Posted June 7, 2015 Tom! Those SBRs here in Commiefornia & made from UNOBTANIUM!!! Ray. Easy... just have Uncle Tom-ass pick up a lower in AZ. He can bring it with him on Thanksgiving. Then the both of you can do a PPT at the CA-FFL of your choice. Later, you can contact RMW Xtreme for the pistol caliber upper of your dreams. You don't have to make it a short barrel. A 16" (OAL) barrel works fine as well. Quote Link to comment Share on other sites More sharing options...
98Z5V Posted June 7, 2015 Author Report Share Posted June 7, 2015 My 16"-barreled AR45 is damn accurate on steel at 200 yards - whoda thunk it. <thumbsup> The extra barrel length keeps those things moving. Quote Link to comment Share on other sites More sharing options...
edgecrusher Posted June 7, 2015 Report Share Posted June 7, 2015 Idk, a 9" is awful tempting... In .45. Another sbr? Sure why not. Quote Link to comment Share on other sites More sharing options...
392heminut Posted June 9, 2015 Report Share Posted June 9, 2015 They have BCGs for 9mm Colt, 9mm Glock cut (it's different than the Colt, so it strips from a Glock mag), .357 Sig BCGs, and 40 S&W BCGs. The .45ACP BCG is listed as "coming soon." No mention of the 10mm yet... For barrels, they have 9mm, .40, and .357 Sig, with the .45ACP barrel listed as "coming soon." Also, no mention of the 10mm yet... The BCG's for the .40 S&W should be usable for the 10 MM shouldn't they? I would also think that a 10MM barrel could be made by reaming a 40 S&W barrel.

98Z5V Posted June 9, 2015 Author Report Share Posted June 9, 2015 I'd think so - they're working on the 10mm stuff. Might be worth a call to see where they're at in the process. Quote Link to comment Share on other sites More sharing options...
Robocop1051 Posted June 9, 2015 Report Share Posted June 9, 2015 I've watched the Glock videos shooting .40s&w in a 10mm... it should be doable in an AR. Quote Link to comment Share on other sites More sharing options...
392heminut Posted June 10, 2015 Report Share Posted June 10, 2015 I would love to build a 40 S&W AR-15 but those parts are just too rich for my blood at this point in time! Quote Link to comment Share on other sites More sharing options...

Jon Beaudry of DDLES ripped off a bunch of people. Not only customers, but his investors too. His investors took him to court and dissolved DDLES.http://www.ar15.com/forums/t_3_15/600709_DDLES_Update___Spoke_to_Jon.html Quote Link to comment Share on other sites More sharing options...
