I have experience with two different Fal and alsoa SAR-4800.
All will hold 2MOA with junk ammo.
One is scoped and will easily shoot under 1MOA without adjusting Regulator.
You gain a little accuracy with more recoil "locking" it down.
Not really worth the trade off unless you are shooting beyond 400 yards.

I don't usually hunt with them but I have with success in the past.
