D.R.D. Posted January 11, 2014 Report Share Posted January 11, 2014 I've got one of those darn sad & lonely lowers, just crying for company. It's an Areo Precision. It will be getting a ALG ACT trigger, ambi selector, Umbrella 23, BCM mod 1 or 3 grip, and M4 stock. But,...it needs an upper. I've already got a DI in 5.56, but was thinking either piston, or another caliber all together. So, I've narrowed it down to these: http://www.huldraarms.com/uppers/product_96b0941ad4da/ Made by Adams Arms Already have everything else that is compatible from my other 5.56 Only need to add sights/optics (Thinking Troy HK-style with a Primary Arms Micro) OR: http://www.57center.com/6m8/ar57-upper-assembly.html Just looks fun Cool to have another caliber 5.7 cost about the same as 5.56 This would just be to have 'another' upper. Could be used for tactical training, plinking or just plain fun at the range. Both uppers would wind up costing about the same. I'm open to other ideas, but want to keep the cost down. If anyone has had any experience with either of these (or similar), I'd love to hear the pros/cons. Cheers, DRD Quote Link to comment Share on other sites More sharing options...
Rsquared Posted January 11, 2014 Report Share Posted January 11, 2014 I'd say go 300 BLK. It's a fun round (a little pricey though), and everything from a 556 rifle will work with it(except the barrel of course). Quote Link to comment Share on other sites More sharing options...
D.R.D. Posted January 11, 2014 Author Report Share Posted January 11, 2014 Yeah, I looked at 300 blackout. I've heard it runs really well suppressed. I don't quite understand it's appeal though. What is it supposed to do that 5.56 doesn't? Quote Link to comment Share on other sites More sharing options...
Rsquared Posted January 12, 2014 Report Share Posted January 12, 2014 You've got 30 cal stopping power at longer ranges. Quote Link to comment Share on other sites More sharing options...
D.R.D. Posted January 12, 2014 Author Report Share Posted January 12, 2014 I've heard about some QC issues with the AR57. No hard stories, though. Still looks fun. Very curious about the piston. Heard good things about AA. Quote Link to comment Share on other sites More sharing options...
Robocop1051 Posted January 12, 2014 Report Share Posted January 12, 2014 The AR57 has funky mags. When they aren't fully loaded, the rounds can jump inside and turn... so I hear... I may just be spreading bad rumors?? ?? ?? I'd be all over a 5.7 upper if it used standard mags, or even a special mag block to use the FN FiveSeven mags.

D.R.D. Posted January 12, 2014 Author Report Share Posted January 12, 2014 Good point. Really, it shouldn't be all that hard right? All that's needed is a 5.7 mag that would fit into the AR15 magwell, right? Quote Link to comment Share on other sites More sharing options...
Robocop1051 Posted January 12, 2014 Report Share Posted January 12, 2014 As for the 300Blk... Some think the 300Blk is a great suppressed round. I ask what was wrong with the .45 ACP? If you look at the ballistics (220 grain .30 cal vs a 230 grain .45 cal) they are pretty dawned close. I like the lighter, super sonic stuff. It's very similar to a 30-30, with a bit better performance down range. Since suppressors are a no-no in CA, I use the 110-125 grain stuff. It's literally the American AK round. For a sub 300 yard round, I'd take it any day over the 5.56 pellet. I still plan on building another 7.62x39 upper for all around plinking and wasting ammo. It's almost to the point that it's cheaper to shoot than .22lr... it's definitely easier to find! All I'm looking for to complete my next build is: • 7.62x39 NiB coated bolt • 7.5" - 9" Melonite treated barrel I'm going to build it around a pistol length Adams Arms piston system. I hate cleaning up after Soviet ammo, so I'm building a SUPER clean shooter. Quote Link to comment Share on other sites More sharing options...

D.R.D. Posted January 12, 2014 Author Report Share Posted January 12, 2014 Forget i asked...i dont wanna know. Lol Anyone run 9mm uppers? Quote Link to comment Share on other sites More sharing options...
98Z5V Posted January 13, 2014 Report Share Posted January 13, 2014 MikeDaddy does - we just shot his today. I'll have one running before too long. I know Drew has a pretty sweet 9mm AR also. Drew and I also have AR45 setups - was running my 45 today as well. Pistol-caliber stuff is WAY different than rifle-caliber. There are a few DI systems out there that are great, but most pistol-caliber ARs are blowback operated. Quote Link to comment Share on other sites More sharing options...
blue109 Posted January 13, 2014 Report Share Posted January 13, 2014 98s .45 sold me. It feels so nice. Quote Link to comment Share on other sites More sharing options...
D.R.D. Posted January 13, 2014 Author Report Share Posted January 13, 2014 What make are the 9mm or .45 uppers? Quote Link to comment Share on other sites More sharing options...
Robocop1051 Posted January 13, 2014 Report Share Posted January 13, 2014 Ron @ rmwxtreme.com makes a DI pistol upper. I believe he has 9mm, 45cal, 7.62x25, 10mm, 40cal and 357sig. Not sure which ones are DI and which are blowback. I know the 45 and 10mm are DI, just vague on the rest. Quote Link to comment Share on other sites More sharing options...
