Sorry, I was sitting in one of my favorite deer stands when I snapped that picture. Gun is a 16" DPMS slick side with Magpul furniture. Adj Gas block tuned to run both suppressed and unsuppressed. Currently is topped with a Vortex HogHunter 3x12x56 in Aero mounts, and sporting a SilCo Harvester 762. I have upgraded the trigger to a LaRue also. Taken a couple of deer with it. I've also got an Adams Arms 308 with adjustable piston and a Burris scope. Normally, I hunt with a 7.62x39 AR suppressed with Vortex Viper on it. Short ranges and a lot lighter. I think I have a video of it being shot in tight woods for those wondering how loud it really is. Hint: 22lr rifle is louder.
