Sick of seeing my unusable, low-round count BCM M4 taking up real-estate in my gun safe.
I am mulling the idea of harvesting all the parts and transplanting on to one of these MRA straight pull bolts.
MRA's website doesn't seem to discuss how the MK II receiver set differs from its predecessor?
What are the differences ? Is one better than the other ?
Also, are there any common problems with these receivers ?
