Compensator?

[Lastrites]

Calvarez with the BCA 20" barrel alone tipping the scales at 3lbs+ I'd say keep it simple as Kilco advised, your set up is going to have plenty of heft to it to minimize most recoil and barrel movement. I ended up going with a flash comp as my fairly lightweight 16 had just a bit more muzzle movement than I prefer and wanted to tame it a bit, just attached and awaiting time for a test drive as for actual felt recoil it has nothing to complain about.
