I currently have a STAG carbine that I put together and a Bushmaster with a 20" HBAR A2 upper.
I am planning on acquiring another 16" carbine upper, which will be going on the Bushmaster lower for the time being.
I won’t likely be putting a tremendous number of rounds through it, but would like to take a good carbine class next spring. I would just like to have a high quality, essentially mil-spec upper.
Agreed… can’t go wrong with either. Honestly I haven’t used a BCM, I’ve been exclusively LMT (just by chance). Never had a problem with them… They make quality BCG’s.
