But still a viable topic and one with some new technology. The new L6 cone breaks are just one of many with the forward break system. My dad had one on his 7mm08 AR made for him several years ago. It wasn't the L6 but was similar technology. I have to say it is much quieter than any break I have seen. I think it actually dampens the sound a bit. Not much but a couple of decibels. I know his AR is quieter than my 7mm08 bolt rifle. Now before you ask why the old man had a break installed on a 7mm08, that rifle was purpose built for longer range hog shooting so he wanted to minimize as much muzzle lift as possible so he could get on another hog in the pack if he ran across a sounder at range. But he didn't want something that would blow his hunting buddies ears to hell.
