.308 buffers?

[BGREID]

I recently purchased a PSA .308 stripped lower. I would like to put a fixed rifle stock on it. What type of Buffers / buffer tube and springs do I need and where can I get them. The usual places just have 5.56 type parts.

I recently purchased a AR10 type stripped lower. I would like to put a fixed rifle stock on it. What type of Buffers / buffer tube and springs do I need and where can I get them. The usual places just have 5.56 type parts.

For a fixed stock A1 or A2 configuration you can use an A1/A2 rifle receiver extension, AR-10 or LR-308 rifle action spring, and AR-10/LR-308 rifle buffer. Note, the AR-10 carbine and rifle action spring are the same, but the LR-308 rifle action spring is different from the LR-308 carbine action spring.

The standard A2 rifle receiver extension works.
You'll also need an AR10 rifle buffer and spring. https://www.primaryarms.com/AR10_Rif.../armea1090.htm
