I have a BM A2 upper just sitting in a closet gathering dust. It has a 14.5" HBAR with AK-style brake on it. I'd like to lighten it up a bit and swap the MB for a good FH with enough length to keep it legal. I'll probably put an EOTech on a CH co-witness mount.
Any suggestions on what diam. to go with? Should I recontour the whole bbl.? What's the best FH (that adds 1.5" in length)?
I'd really like to hear from folks who've had something similar done. I hear many good things about ADCO and I live close enough to drive to the store.
