EasyEJL Posted September 28, 2015 Report Share Posted September 28, 2015 I bought the upper/lower combo, the 15" rail, and the 16" AP4 barrel from Reidman. I've saved up a little bit o money, so I'm trying to figure out the rest of what I want to buy. Pretty settled on the Luth MBA1 stockhttp://www.luth-ar.com/product/the-mba-modular-buttstock-assembly/the triggerless LPK + upper PK from armalite, have a nice trigger here waiting (can't recall the brand, bought it from another member here) So i'm more or less down to buffer tube/spring/buffer, BCG (LR308 pattern), gas block + tube, and muzzle device after that. Trying to keep it budget friendly, what suggestions do you all have? Not sure if I really need adjustable gas block on this one as i'm unlikely to suppress it Quote Link to comment Share on other sites More sharing options...
survivalshop Posted September 28, 2015 Report Share Posted September 28, 2015 DWilson has 10% off his 308 parts ( BCG & such ) , Look in the 308 Parts section or the Coupon section .Use the AR 10 rifle set up for your Receiver Extension & buffer system .What gas system length is that AP 4 BBL.? If its a Carbine , you may want to use an adj. gas block . Quote Link to comment Share on other sites More sharing options...
EasyEJL Posted September 30, 2015 Author Report Share Posted September 30, 2015 It is a carbine. So you don't think an LR308 receiver extension/buffer/spring is a good idea then? since I was looking at that Luth stock, they have a package that comes with one, which was why I was thinking that Quote Link to comment Share on other sites More sharing options...
blue109 Posted September 30, 2015 Report Share Posted September 30, 2015 That luth stock uses rifle extension right? If so you will be G2G with the LR rifle buffer and spring. Quote Link to comment Share on other sites More sharing options...

GreyGoose Posted September 30, 2015 Report Share Posted September 30, 2015 FYI, as mentioned in another thread they just released the carbine length versions of the Luth-AR, the MBA-3 & 4, in case you were interested in going that route.

EasyEJL Posted September 30, 2015 Author Report Share Posted September 30, 2015 hmm dangit, I didn't want to wait, but that would probably be nicer. On amazon, they have the luth MBA-1 with the LR308 buffer/tube/spring for $160 and I have some amazon gift card funds too. But it would be nice to have collapsible Quote Link to comment Share on other sites More sharing options...
EasyEJL Posted April 1, 2016 Author Report Share Posted April 1, 2016 Well, I've mentally rotated around some on this. What i'm going to do is get the LUTH-AR MBA1 in FDE for my dpms pattern 308AR, and the move the Mako GL-Shock carbine from that onto this. I poked around a little, were there any specific issues or anything else I should be looking out for on assembling up the lower + upper?

EasyEJL Posted August 30, 2017 Author Report Share Posted August 30, 2017 ok, so actually putting it together now, with a armalite 10A lpk. everything EXCEPT the bolt catch goes in fine. the bolt catch slides in smoothly right up to the last 1/16 of an inch or so then binds. did anyone else run into this? I'm guessing its just slightly malformed, which I really didn't expect from an armalite piece. Outside of that, the rest went together smooth as silk Quote Link to comment Share on other sites More sharing options...

EasyEJL Posted August 30, 2017 Author Report Share Posted August 30, 2017 what i need to do is run a mic across it and see what the width difference is from the one end to the other on the bolt catch. because the lower itself seems perfect as the catch slides in all the way just up to the end.

survivalshop Posted August 30, 2017 Report Share Posted August 30, 2017 So almost two years in the making , you have to have a sweaty trigger finger by now . Just make sure there are no hidden Burr's inside the Lower Receiver where that Bolt Stop works . Make sure you check that hole for the Bolt Stop Buffer & Spring also .

odie64 Posted August 31, 2017 Report Share Posted August 31, 2017 Armalite (AR10) and DPMS (LR308) use different style bolt catches. I ran into a problem with the DPMS style bolt catch hitting the upper and making it inoperative on my PSA PA10 Gen 2 build. PSA uses a Armalite style bolt catch. you might want to check to see if the bolt catch is hitting the upper causing it to be "pinned down" and can't move up the lock the bolt back on an empty mag Quote Link to comment Share on other sites More sharing options...
98Z5V Posted August 31, 2017 Report Share Posted August 31, 2017 Knock the lower corner off the bolt catch - it's what is binding. Lower corner, furthest from the pin hole location. See the square corners on these Armalite pieces here?: You'll need to knock that 90* corner off, and make it into something like this here: Quote Link to comment Share on other sites More sharing options...

EasyEJL Posted September 6, 2017 Author Report Share Posted September 6, 2017 it turned out to be the area near the pin hole, was a little thicker than the rest. some sandpaper and it went together. The rest of the rifle is done too, excepting waiting on a 308 carbine buffer + spring.... Quote Link to comment Share on other sites More sharing options...
