I am assuming that all SP1's have the large front holed pivot. What pre-ban style uppers have you used that have the best fit using an offset pin ? Or better yet is there any i should avoid. I'm considering an M4 type upper.

All you need is an adapter pin, any mil-spec (.250hole) should fit. Bushmaster and brownells have the adapter pin [url]http://www.bushmaster.com/shopping/lowers/nes-06.asp[/url] [url]www.brownells.com[/url]

I have an SP1 with a milspec upper and the offset pin. It is loose as all hell... way more than any other AR I own. Are there better offset pins or solutions? Will the accuwedge take care of this slop?

I purchased an offset from Bushmaster tried my PCR4 upper on it very snug fit.
