I'll be running an Omega on my 14.5" BCM LW ML upper. Currently it runs like a top with blue sprinco and H2; soft shooting with a smooth recoil impulse. I'm having the gunsmith unpin the FH and repin an ASR FH. I'll be adding a longer rail at the same time (ml magpul currently) and I'm contemplating shaving the FSB down vs AGB to run an extend rail. Thoughts? Thanks
