I have an SP1 lower and a large hole A2 colt 16in upper w/lightweight barrel bolted on. My question is...is it ok to use the latest RRA collapsible stock "as is"...referring to spring and buffer?

Any help would be appreciated.

You need to use the buffer and spring that come with the RRA stock. Just so you know the collapsible stock is for Per-Ban only . Good luck

So the concensus here is that the RRA Collapsible stock, buffer/spring and all will bolt on and work fine? Cause I had someone else claiming that I should only buy the colt milspec because specs are different between bushmaster and RRA. What do you think? Very nice rifle by the way.

The lower "rail" on a Colt, 4 position, receiver extension is narrower than the "rail" on a RRA/BM extension. A RRA/BM stock will, loosely, fit on a Colt extension, but a Colt stock will not fit on a RRA/BM extension. The Crane, Vltor, and LMT stocks require a Colt (which is the Mil-Spec) receiver extension.

Thanks Guys....I'm going to buy the colt unit and play it safe. And heck, for a few bucks more, my carbine stays all colt. I'm pretty excited....two rifles in one now, the A2 Carbine or the classic SP1. Apreesh! Jim
