Solid

Bought this to go on my carbon lower. Really liked the idea of the up caliber choice to use the combo for Whitetail. I also liked the flexibility of subsonic and supersonic rounds without having to buy new magazines.
Really good shot group consistency out of the box. Took two deer this season with the 156gr supersonic round. One through the lungs at 90yrds and one through the shoulders/spine at 25yrds. Wasn't too proud on the second because I was winded and pulled the first shot. But the smooth cycle on this upper let me retain sight picture and take it with my second shot. Something I'm not sure I could have pulled off with my old lever action 30-30. Also with the solid contact it did knock the deer down, something that made me fell better about its performance

Well Made Upper + Great Caliber

I bought this to go with my suppressor and just this afternoon bagged my first coyote with it. Love the caliber and the ability to shoot subsonic. Everything is made well and my uppers switch out quickly with the pulling of 2 pins. This gun can hit a 100yd target and also a 200 yd target consistantly. I haven't really put enough rounds through it to know how tight I can get the shot groupings but for what I do it works great! I love the ability to switch calibers quickly depending on what I am hunting, shooting, or have ammo available for. Now if only .300 AAC ammo would be more available!

Black Out Review

This gun is a wicked little monster to hunt or target shoot.Using a 110gr.slug I put 10 holes in a 2 inch circle,at 100 yards,scoped at 200 yards the same
results.A great gun,with a great 30 cal.round.
5 Stars all the way
