AngelDeVille Posted June 2, 2015 Report Share Posted June 2, 2015 That's the smartest thing I did when I built mine.... I ordered the Armalite LPK. I figured that if anyone knew how to make the parts, they did. Quote Link to comment Share on other sites More sharing options...
98Z5V Posted June 2, 2015 Author Report Share Posted June 2, 2015 I think the Armalite AR10A pattern bolt catch would be the more appropriate one to run in this rifle. I'll continue to fit the 10B bolt catch, but get the 10A bolt catch on order. Quote Link to comment Share on other sites More sharing options...
AngelDeVille Posted June 2, 2015 Report Share Posted June 2, 2015 (edited) I have a spare, I think it's an A, I don't need it. trade you for the B EDIT: yep I have a spare A, PM me your address Edited June 2, 2015 by AngelDeVille Quote Link to comment Share on other sites More sharing options...
98Z5V Posted June 2, 2015 Author Report Share Posted June 2, 2015 The 10B catch is already in surgery, brother... <lmao> Quote Link to comment Share on other sites More sharing options...
AngelDeVille Posted June 2, 2015 Report Share Posted June 2, 2015 (edited) If you just took a 1/16" off the top I was gonna do that anyway.. Edited June 2, 2015 by AngelDeVille Quote Link to comment Share on other sites More sharing options...
98Z5V Posted June 3, 2015 Author Report Share Posted June 3, 2015 (edited) ***Bottom to top, bolt stop area: Armalite part is 0.590” high. Aero part is 0.520” high. Might have some work to do here, shaving down the Armalite… Surgery complete! Got the Armalite 10B bolt stop down to 0.530" bottom to top, and she functions like a champ. The Aero bolt stop had that little angle on the lower outer edge, so I chopped the Armalite in a similar fashion - zero need to do that. I also shorted the end of the Armalite to match the length of the Aero - zero need to do that either. I should have checked the thing in the rifle for those areas, but I didn't. Would have saved me time. I did install it, but at 0.590" high, I couldn't even pull the bolt carrier back - it hit. It clears now at 0.530", that's for damn sure. Glad I did it. Pics coming up in a few. Also tossed in the Armalite AR10A-pattern magazine catch... Pics: Edited June 3, 2015 by 98Z5V Quote Link to comment Share on other sites More sharing options...
98Z5V Posted June 11, 2015 Author Report Share Posted June 11, 2015 Barrel swap. Went with the Faxon 16" medium taper, midlength gas, 1:10 twist in .308 Win. Very, very nice barrel. <thumbsup> Quote Link to comment Share on other sites More sharing options...

AngelDeVille Posted June 11, 2015 Report Share Posted June 11, 2015 That looks pretty damn fine to me, I'm hesitant to use a 16" barrel on my next one, but I for sure wouldn't go 20", and I already have and 18".... Such a horrible dilemma. Quote Link to comment Share on other sites More sharing options...
98Z5V Posted June 23, 2015 Author Report Share Posted June 23, 2015 (edited) I've been picking up parts to build up the second one, and figured I'd try something out. For the second one (nowhere near built yet), I selected the Armalite AR10 Carbine receiver extension, EA1095 spring and the AR10 Carbine buffer (an AR15 Carbine H3 buffer is exactly what it is). Swapped those extension parts over to this running rifle - guess what? No bolt face overtravel, way beyond the bolt catch... Re-measured the internal depth on the AP parts and receiver extension, and came up with 7.100" again. Should be 7.000", just like an AR15 Carbine receiver extension. Short little buffer still comes in at 2.504", which is right where it should be. The spring was weird as hell. 10.75" long (relaxed length), 26 coils, wire diameter 0.070". Fuckin' weird spring... Overall suggestion: Don't hesitate to build an Aero Precision 308 set - just don't use their carbine receiver extension kit. I'll shoot it on Thirsty Thursday and see how she functions, with the Armalite parts. I don't predict any problems.

unforgiven Posted June 23, 2015 Report Share Posted June 23, 2015 When I called Aero about that fukin upper,I also spoke to Tech about reciever extenstion and he said no one has had issue. <dontknow> So I can just change it out with an AR15 tube ? That's what I'll do.RRA has a sale going on.Brother Spartan doesn't seem to have any issue's not sure if he has factory tube. Quote Link to comment Share on other sites More sharing options...
98Z5V Posted June 23, 2015 Author Report Share Posted June 23, 2015 (edited) I never called them about an issue, because I didn't buy the parts from them. I bought that lower already built, from a member here, but that was specifically listed in his parts list - hell, we helped him build that rifle. That receiver extension is too deep, and that fuckin' spring is weird. It doesn't even go (belong) in an AR15. Brother, I'd say just buy some quality mil-spec AR15 carbine receiver extension, and the Armalite EA1095 spring, and run it. the buffer they have is good - measures out, and it's a heavy little fucker. For them to say no one has had an issue - well, maybe nobody has told them that there's an issue. I sure as hell had an issue with it, though. <dontknow> Edited June 23, 2015 by 98Z5V Quote Link to comment Share on other sites More sharing options...

98Z5V Posted June 24, 2015 Author Report Share Posted June 24, 2015 Armalite 10B bolt catch is out. I'll explain more once I get my hands on the Armalite 10A catch, and toss up pics of all 3. Note to AP builders - don't use the Armalite 10B catch. Quote Link to comment Share on other sites More sharing options...

Robocop1051 Posted June 24, 2015 Report Share Posted June 24, 2015 I still have a custom, one off, stainless steel catch. It was made for me by SI-D... back when they were small and did stuff like that. All yours if you want it. Quote Link to comment Share on other sites More sharing options...
98Z5V Posted June 24, 2015 Author Report Share Posted June 24, 2015 (edited) The tang on the front is wider, sturdier - but doesn't have the reach. Wasn't locking the bolt back on the last round. That was consistent across steel DPMS mags, Pmag LR20s, and Lancer L7 mags. Never locked the bolt back on the Lancers or Pmags not even once, and would get caught by the DPMS about 1/2 the time. Won't work reliably in the AP sets. Plus, you have to fit it for the AP set. It's not fun to fit it. Edited June 24, 2015 by 98Z5V Quote Link to comment Share on other sites More sharing options...
TnBilly Posted June 25, 2015 Report Share Posted June 25, 2015 98... you're reaffirming what I've heard about the Aero and PSA receivers being the same, at least dimensionally. My PSA lower uses a AR15 buffer-tube with a 308 buffer and weight IIRC I know the take-down pin is all PSA........ AR15 width, 308 diameter Guess I really need to sit down and document the PSA/Aero lower differences as compared to the DPMS and AR-308 drawings.
