Just finished my Black Friday shopping, and ended up with a Sons of Liberty Gun Works 12.5" upper and a BCM MCMR 10" handguard. The upper comes with the barrel, gas block and gas tube installed; but no handguard or muzzle device. I've never built an upper, so here's my question:
Can I remove the milspec barrel nut and install the MCMR rail without removing the gas block? I don't want to mess with the factory installation especially since set screws are used.
If anybody has installed a BCM rail, any advice would be appreciated!
ETA: Crap. Just realized that the barrel nut won't fit over the low profile gas block. Since I'll be removing the gas block, what is the best thread lock to use when re-installing it?
