First .300 Fireball build.

I built this pistol, which will soon be a suppressed SBR once the paperwork returns from the ATF.

I would like to build my .300 Fireball upper to have the same handling qualities.

I know the profile can be handled by many barrel makers (I have PM'ed tp555) but I don't know if I can fit an adjustable pistol gas block under standard CAR handguards. I don't mind cutting and grinding on the handguards if needed.

Any input appreciated. If more information is needed, just let me know.
