Hey guys,
Before you ask, yes I did a search but Im still confused.
I have a Colt marked Match Rifle, lightweight postban rifle I bought before the M4 craze. I would like to keep it all Colt, but as everyone knows Colt prices are crazy. Ive read about the different pin size uppers and lowers and I think Im more confused than when I started. I guess my question is, if I purchase an M4 upper (RRA, Bushmaster, etc)there is a way to mount it on my colt lower? I see that Bushmaster has a pin kit and Im assuming that would be all I need.
Next question: Can I use my colt bolt or are the bolts matched to the uppers in some way. I was under the impression that the bolt should be interchangable between rifles. With the plethora of uppers out there I want to make sure my colt bolt won't blow up another manufacture's upper.
Thanks ahead of time for any answers.
