    I have two Colt uppers on Stag lowers. Both are small pin uppers, and fit very good.

    If upper and lower have same pin, you should be good to go. I have mixed and matched colt, bushmaster, stag, bcm, dpms, etc uppers and lowers with no issues.

    Can a Colt upper be fitted to a Bushmaster or other small pin lower?

    You will need to get the offset pin for this then. Not a real big deal.
