Great on the range. - Kaw Valley Precision 3.25in Magnum Linear Compensator

Can't speak for SBRs, but with 5.56 16"+ barrels & bullpups, the concussion is extremely reduced compared to an A2 birdcage. The recoil impulse is flat, and there is no flash visible in daylight. The difference in shot volume isn't true suppressor level, but for less than $50 it's significant. Obviously it heats up under sustained fire, but with no issues. Maybe use a crush washer if you want to keep it in place. Build quality is very solid, and the threading is well machined. No long term wear concerns.

Highly recommended if you don't want to be that person on the range no one wants to stand near, or if you simply value your dental fillings as they are. It's a diet suppressor that's legal in states that don't like flash hiders.

Pros: directs concussion energy from any barrel length away from the shooter, tames flash, flattens recoil (nothing crazy like a comp), good construction, and reduces perceived sound significantly. (Don't be dumb, always wear ear pro.)

Cons: may come loose without a crush washer if you don't snug it down enough. Don't expect to get the interior entirely clean.

TL;DR: buy one because it makes your firearm more pleasant to operate
