Installing PRS on M&P10 (Detailed)

[Jwteknix]

Did u use the carbine spring or the rifle spring? Did you use it with the spacer?

I tried the carbine spring with spacer, but was still short stroking. I am now using the DPMS A2 Buffer Spring with no spacer.

Are you still using the stock buffer? And since it's no longer short stroking? Thanks

Yup, still using the stock buffer, just tossed that A2 spring in there and let her rip. No issues since either. I have taken a couple range trips between then and now and no hang ups. Still shooting bulk mil-surplus ammo with no problems through DPMS and Magpul magazines.

I broke down and ordered the PRS, A2 tube and spacer. Thanks for the post on how to do it and what was needed.

I am attempting to install a Magpul MOE stock on my M&P 10 and have no idea what the point of the spacer is or where is goes or if the spacer that midwayusa sent me is right. I know that it's probably common sense; and that would be why I'm confused. Please help. I am just trying to use the regular MOE stock with the factory buffer tube and spring. I don't see why a spacer is needed as the MOE stock fits just like the factory stock. The spacer midwayusa sent my is about 3/4 of an inch long. All it does is stop the stock from going to the shortest setting and it moves freely around the empty space when the stock is extended.
