Can't help you until you post up the internal depth of the extension. Quote Link to comment Share on other sites More sharing options...
Robocop1051 Posted February 6, 2020 Report Share Posted February 6, 2020 You don’t “have” to use a specific buffer tube, but you do have to have the correct buffer and buffer tube combo. Armalite uses a specific setup, and DPMS uses a specific setup. Both/either are fine, but you can’t mix parts from different families. The Armalite AR-10 buffer tube is also the Vltor A5 buffer tube. DPMS uses a standard AR-15 buffer tube. Quote Link to comment Share on other sites More sharing options...

It is 7” inside tube I cut 10 coils off of spring an now it will lock back but gonna have to work on bolt catch it not high enough to catch without holding it manually but then it just verily catches it .430 “ high an read it suppose to be .500” Quote Link to comment Share on other sites More sharing options...

Cutting 10 coils off the spring isn't the way to do it - you just weakened that entire recoil system, greatly. I'll be that there no bolt catch out there that would grab that speeding BCG, now...
