392heminut Posted January 31, 2015 Report Share Posted January 31, 2015 Ironmonster, think about it. The 308 mag is wider than the 223 mag so yes, the 308 mag catch is different, it has a longer shaft. The 308 bolt catch is different than the AR15 catches too.

D.R.D. Posted January 31, 2015 Report Share Posted January 31, 2015 (edited) Did you see this? http://aeroprecisionusa.com/aspx/store/productdetail.aspx?pid=341 Add the coupon code: "GoHawks12" and the total is $235! I couldn't resist, so I'll see how it mates with my SI-Defense lower. Edited January 31, 2015 by D.R.D. Quote Link to comment Share on other sites More sharing options...
ironmonster Posted January 31, 2015 Author Report Share Posted January 31, 2015 So on Midways parts page they list a AR15/ LR308 Mag catch http://www.midwayusa.com/product/327344/dpms-magazine-release-ar-15-lr-308-matte So am I to make the assumption that all the parts for the Aero are DPMS patten except for the mag catch which is AR10? If that is the case where can I buy the AR10 mag catch as a stand alone part? Quote Link to comment Share on other sites More sharing options...

Which kind of irritates me because now I am commited to a second rifle which I cant really afford or need. But too good of deal to pass up.

crimsonfalcon07 Posted January 31, 2015 Report Share Posted January 31, 2015 I'm managing to resist so far. But boy, that's a good deal. Quote Link to comment Share on other sites More sharing options...
ironmonster Posted January 31, 2015 Author Report Share Posted January 31, 2015 So a little further reading leads me to believe that the DPMS .308 LPK comes with a AR15 mag catch. After 10 minutes of searching I found a AR10 mag catch in stock at Delta Three Tactical and ordered one. Quote Link to comment Share on other sites More sharing options...
crimsonfalcon07 Posted January 31, 2015 Report Share Posted January 31, 2015 You can also get a Seekins precision mag button; that helps. I use the Troy ambi mag release with the seekins button in my Aero build Quote Link to comment Share on other sites More sharing options...

Just have a different barreled upper 20".18", 16" or even 14". <thumbsup> Ar 15 mag catch will work on most 308AR's , some need a longer one . Are you having fun yet , the 308 AR is a different beast then its smaller brother . I think the Amalite's catch is better for the 308AR .

I used to have half a dozen "extra" AR15 uppers but eventually they all ended up complete rifles ::) I can tell you its a bit more stressful at this point trying to sort out the big bore stuff. I'll feel better when I have a rifle that works and a better idea what I am doing. I own 15 or so AR15's and built over half of them from scratch so I thought I had a pretty good grasp of what would be entailed with its big brother. Not so much ^-^ Quote Link to comment Share on other sites More sharing options...
ironmonster Posted February 19, 2015 Author Report Share Posted February 19, 2015 (edited) Over all I am pretty happy with this. I spent a little more money than I planed on but I think it was well spent. My biggest gripe with it so far is just its weight. She is a tank. With a empty magazine and the bi-pod she clocks in at 12.5 lbs With a optic and loaded mag its gonna be 16 pounds! And this is a relatively light 16" barrel. Cant imagine what it it would weigh with a 22" bull barrel! I am hoping this weekend I'll get a chance to see if it goes bang. It is mostly Aero Areo 16" 1/10 Stainless bead blasted barrel Fortis Stainless gas bock. Spikes nitrided gas tube AAC comp/flash hider Aero enhanced upper and keymod rail Aero M5 lower GGG folding sights Magpul UBR stock CMC 3.5lb flat trigger BAD-ASS Ambi saftey AXTS/Raptor ambi charging handle Aero/Fail Zero BGC So know I want to build another one. I suppose that is the way it always works. You learn something and then you want to do the next thing. I think I might try and build a much lighter version of this same rifle. Find a pencil barrel and put on a Magpul ACS-L See if I can get down in the 7-8 pound range. Anyway She is not a Si-Defense or one of the Rainer branded Mega rifles but as she sits with the used UBR stock I am into it about $1350 without sights or a magazine. Right at about half what one of those "fancy" rifles would cost. If it will put 5 rounds in a 2" circle at 100 yards I am gonna call it a win.

98Z5V Posted February 19, 2015 Report Share Posted February 19, 2015 You did a damn great job on that build - that's a nice rifle, man. I like your outlook on this, too... just build another... <lmao> Need some gas tube roll pins, by chance? <laughs> Quote Link to comment Share on other sites More sharing options...
ironmonster Posted February 19, 2015 Author Report Share Posted February 19, 2015 Well, I bought one of the Aero upper/rail combo deals on sale for $235, I picked up one of those $175 BCG from AIM surplus. I got a ACS-L stock, MOE grip another CMC trigger. I got a buffer tube, gas tube, pivot and takedown pins. so I need a barrel, gas block, flash hider, lower, buffer and spring, So another $500-$600 I should have a second rifle kicking around. Two is one, one is none <thumbsup> Quote Link to comment Share on other sites More sharing options...

survivalshop Posted February 19, 2015 Report Share Posted February 19, 2015 The UBR stock is no light weight . Quote Link to comment Share on other sites More sharing options...

D.R.D. Posted February 19, 2015 Report Share Posted February 19, 2015 Do you think it's the UBR that makes it so heavy? Does that barrel have a .750 gas block - or is it a bull profile? Quote Link to comment Share on other sites More sharing options...
ironmonster Posted February 19, 2015 Author Report Share Posted February 19, 2015 Its a .750 gas block, The barrel is not a lightweight, but its not a heavy profile either. Kind of in the middle. The UBR weighs like 1.5 pounds on its own, so Its no lightweight but it does not account for a 12 pound rifle. The bipod probably weighs a pound . I probably need to check my scale. It feels heavy but I was shocked when it read 12.5. I have a HK91 clone that is about 9 pounds though and it does feel considerably heavier than that.

survivalshop Posted February 20, 2015 Report Share Posted February 20, 2015 I think you can get them lighter , but most is in the Barrel & BCG . I don't mind a " Little " weight , the big bores play nicer with some girth to them . Quote Link to comment Share on other sites More sharing options...

BadBoyBilly Posted February 22, 2015 Report Share Posted February 22, 2015 Great build. I have an Aero M5 receiver set sitting in storage. Someday i'll get around to building it out. Got another .308 build I'm slowly putting together..... Quote Link to comment Share on other sites More sharing options...
Dark Halo Posted February 25, 2015 Report Share Posted February 25, 2015 Ok, I have the aero upper and lower along with a aero BCG, I did order the aero take down pins but did not get the bolt catch or mag release. So if I am understanding correctly I will need to get the AR10 bolt catch and mag release? Quote Link to comment Share on other sites More sharing options...
crimsonfalcon07 Posted February 26, 2015 Report Share Posted February 26, 2015 the DPMS bolt catch works fine in mine so far... I've got a Troy mag release and Seekins button and those work great too, in case you want more options. It does sound like the AR-10 bolt catch may work better though. Quote Link to comment Share on other sites More sharing options...
ironmonster Posted February 26, 2015 Author Report Share Posted February 26, 2015 I did not even try another bolt catch as I got the Aero with my other bits. The AR-10 mag release is only maybe 3/16 longer than the AR15 but it does make the difference. I did both the AR10 unit and a Seekins button, but I think just using a Seekins button with a standard AR15 one would work. You only need just a bit more, I had it together with just AR parts and it worked fine there was just not much of the mag release button showing.
