.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 (http://www.brownells.com/rifle-parts/receiver-parts/buffer-tube-parts/buffer-tubes/butt-stock-extension-tube-prod17502.aspx?psize=96), AR-10 or LR-308 rifle action spring (http://www.brownells.com/rifle-parts/receiver-parts/recoil-parts/recoil-springs/buttstock-buffer-spring-std-prod42988.aspx), and AR-10/LR-308 rifle buffer (http://www.brownells.com/rifle-parts/receiver-parts/recoil-parts/recoil-buffers/rifle-buffer-prod42989.aspx). 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_Rifle_Buffer_AR10_Buffer_for_A1_A2_Style_p/armea1090.htm
