Dark Halo Posted February 18, 2015 Report Share Posted February 18, 2015 I just ordered The Aero lower to go with the Upper I have, I currently have a few AR builds under way. I tried the Aero upper on a DMPS and Bushmaster lower and the gap at the back was to much for me. I also noticed the takedown pins would not line up that good on either lower as well. I was going to return it but I have had a 13.8 Troy HP DMPS rail that I could not use until now. I was able to get the lower for 185 and I had a lot of spare parts left over from my DPMS sportical to SASS conversion. All I need is a LPK, BCG and forward assist to put together a complete 16" .308. Still not sure what I will do with it yet as I have a 16" Bushmaster 308.

D.R.D. Posted February 18, 2015 Report Share Posted February 18, 2015 AP seems like quality stuff at a great deal...but not completely compatible with all other OEM parts. Quote Link to comment Share on other sites More sharing options...
crimsonfalcon07 Posted February 19, 2015 Report Share Posted February 19, 2015 Which is often true of virtually any 308 AR part, it seems. Cross-compatibility isn't exactly the strong suit with 308's, considering the lack of milspec. Hence the oft-repeated advice to always buy a matched set.

D.R.D. Posted February 25, 2015 Report Share Posted February 25, 2015 Farkle, Would this one work as well as the Vltor A5? I'm curious as it's designed to be anti-tilt: http://www.primaryarms.com/PWS_Enhanced_Buffer_Tube_308_p/4bt308b1.htm Quote Link to comment Share on other sites More sharing options...
98Z5V Posted February 25, 2015 Report Share Posted February 25, 2015 Nope, needs to have an internal depth of 7 5/8". The only way you'll get that one to run on your .308 build is to use a DPMS-based LR308 compatible buffer. Quote Link to comment Share on other sites More sharing options...

The only way you'll get that one to run on your .308 build is to use a DPMS-based LR308 compatible buffer.Actually the .308 EBT is AR-10 pattern so yes, it'll interchange for the A5 receiver extension. My MK216 came with one, which I've swapped onto an AR-15 lower with A5 buffer.POF also makes an anti-tilt AR-10 receiver extension. This is what I replaced the EBT on my MK216 with (since I needed shorter LOP options). Quote Link to comment Share on other sites More sharing options...
98Z5V Posted February 25, 2015 Report Share Posted February 25, 2015 You're saying this: http://primaryweapons.com/accessories/buffertubes/#.VO0-ZCyzm2A works in the .308 ARs, without a short DPMS-based buffer? Quote Link to comment Share on other sites More sharing options...
FaRKle!

It's 8.25" long. Edited February 25, 2015 by FaRKle! Quote Link to comment Share on other sites More sharing options...
D.R.D. Posted February 25, 2015 Report Share Posted February 25, 2015 Thanks, Any advantage to the POF over the PWS in this case? Quote Link to comment Share on other sites More sharing options...
FaRKle!

It also probably weighs a bit less. Quote Link to comment Share on other sites More sharing options...

98Z5V Posted February 26, 2015 Report Share Posted February 26, 2015 Yes, the .308 version works with AR-15 buffers when on a .308 AR. It's 8.25" long. Overall length won't matter one bit - not even if it's 25" long. For it to run the AR10 Carbine buffers - and any other AR15 buffer - it needs to have an internal depth of 7 5/8", or very damn close to that. The standard AR15 Carbine receiver extension has the internal depth of 7", or very damn close to that. Quote Link to comment Share on other sites More sharing options...
