I bought a Rock River Arms mid-length upper (chromed lined) a few years back before I knew much about brands/standards and the like. I later learned how RRA didn't really follow many standards. Being that most were related to the bolt/carrier, I bought a BCM bolt/carrier group and have been happy with it.
Lately, I've been thinking of how important the barrel is and knowing how the RRA barrel isn't a 1/7 twist, isn't MPI/HPT, and the feedramp isn't as a good as a BCM ramp, I've been considering getting a BCM upper. The thing is, I don't want to spend money for something that is mostly irrelevant. I see it similar to the Kahr PM9 - CM9 thing where, IMHO, there isn't sufficient reason to go with the more expensive PM9 so I went with the CM9.
So my question is, do you consider the differences between the RRA upper and the BCM upper enough to purchase a BCM upper?
RRA:
Rock River Arms: Mid-Length Upper Half
BCM:
BCM BFH 16" Mid Length Upper Receiver Group
Thanks.
