what buffer tube/spring/buffer for spr?

[JBrady555]

Just got my 18" rainier spr match barrel. It's going on my vltor mur upper with bcm full auto bcg. I want to run a magpul prs stock if I can ever find a black one in stock somewhere. What buffer tube and components do I need for this spr barrel and prs stock? Thanks.

Go to the MagPul website. They'll have all the technical information you'll need to mount a PRS stock properly

Red barn armory shows them in stock. I've purchased from them before and they are good to go. The PRS installs over any mil spec rifle extension, so take your pick. As far as a buffer, start with a standard rifle weight and move up or down in weight depending on the length of your gas system and ammo selection.

Ranier Arms spec's the barrel with a rifle length gas system. And having installed a MagPul PRS for someone, I know it, also, is compatible with the rifle buffer. That's where I'd start.
