Right now I have a Spike's Tactical ST-15 complete rifle (found here: http://www.spikestactical.com/new/z/...ine-p-387.html )
I've been thinking about a .458 SOCOM, and started wondering...could I just buy a RRA .458 SOCOM upper and match it to my Spike's lower? Does anyone know if this would work, or what other parts I might need to make it compatible?
Here's the upper: http://www.rockriverarms.com/index.c...ategory_id=424
or this one: ( http://teppojutsu.com/uppers.htm )
Feedback greatly appreciated
