Re: AR10 and DPMS question--

I'm using a AR10 Magpul PRS and an A2 receiver tube. I was about to buy a DPMS buffer and spring, but got a little confused after I realized I was using an Armalite BCG and barrel extension.
Again, thanks! </div></div>
Using the PRS with the A2 RE on the 7.62 your 7.62 rifle buffer is about 3/4" shorter, 5.250 total length. The buffer spring is also different than the 5.56 rifle version.
ArmaLite or DPMS 7.62 rifle buffers should be fine for your application. When you use a collapsible stock you need to look at heavybuffers.com for the best solutions.
I have a new AR-10 rifle buffer and spring I'll sell cheap, if interested PM me.
