I see that you have different options for pinned flash hiders/brakes on the 14.5" BCM uppers.
If you are installing them, is it possible to get a low pro gas block installed, and maybe even get the delta ring assembly removed?
Or do you receive them with the pinned muzzle device already installed?
Im looking for an upper, preferably 14.5" BCM thats ready to accept a TRX Alpha rail.
Thanks
