The "truth about guns" did a muzzle brake shootout, single shots from an AR-15 on a gun strapped to a sled measuring barrel rise, rifle movement etc... Granted a braked gas gun even on single shot will reduce more than a braked bolt gun, but it shows how efficient each are. The VG6 was one of the better ones.

That “shootout” was the reason I tried one in the first place.
How does gas escaping get optimized for semi auto versus bolt? Sure the gas tube and action mitigate some recoil... but I'd be very surprised if there was any design change at the muzzle end. If reducing recoil is #1, then platform shouldn't matter in how it vents/functions.

5 rounds through my ultralight, keeps the scope on target nicely.
