Just thought I throw this out there since a lot of you guys are building up a ar. I've been after a way to be able to shot my AR-15 without the need of hearing protection. I got some 6.5 acres I patrol from time to time(sometimes I see evidence of trespassing and trashing up my pond) so I typically bring protection. Anyways, I think I found the solution, Levang Linear Compensator, tonight I was testing it out, 30rds without hearing protection and still could hear perfectly. The gun isnt quite by any means, but your ears and anyone behind the gun wont ring at least. It doesn't fully kill the flash, I get a small one, but it's below the line of sight, and causes no problems, unlike the A2 birdcage with sometimes a flame flys across the sight picture. Recoil is directed straight back, and keeps the muzzle level despite having nothing on top. Just a suggestion to those wanting something semi-hearing safe, without going to suppression. Now it doesnt reduce the report, just redirects it, so it all good on the legal side. Yeah I know it isnt set straight, but I've told they are suppose to set in slight angle, I even notice a Magpul prototype gun with one, and it was crooked too. Plus I dont think it even matter how it's set, every hole is the same. http://www.defensereview.com/stories...ul%20PDR_5.jpg Or maybe just because the threading even with a crush washer, makes it seat crooked.
