Ar10 build ?

[kris smith]

I'm looking into building an ar10 and I have been gathering parts list of what I may want. But I can't find a few parts so question is will a gas block gas tube upper parts kit and mag lock for ar15 work on a Dpms pattern ar10 rifle length gas ? If not where can I find these parts

Yes

Yes, but for the record DPMS is a SR-25 pattern and not a AR-10. Not trying to knit-pick, but it will help you in your search for parts. And you will need this..

it is the only lower part that is different, and maybe the buffer.

I've sourced my most of the parts from Rainer I got there lpk so the upper parts and all that will work from a 15 what about buffer ,tube ,spring ? I'm running the sr25 pattern mega maten upper and lower and a prs stock rifle gas system what buffer stuff do I need sorry totally new to the .308 AR world

The DPMS 308 Spring (DPMS# :308-BS-10B) and buffer (DPMS# :308-BS-11) .

The spring:

AR10 Buffer should work:

But, Midway has the spring and buffer in stock.
