Spent part of the day shooting a buddy of mines 7.5" Adams Arms upper. The thing I can say without hesitation was that it was a helluva lot of fun to shoot!!! I did not find the blast to be anymore obnoxious then a 10.3" MK18. Shots on steel at ~75 meters all day long. I personally think this would make a great "truck gun". One has to remember its intended purpose. 100 meters and closer I think this would be a very nice concealable option. It belongs to a good friend of mine who is an active duty 3rd Group guy. He helped sell me on it. I had a huge grin the entire time.

Just my two cents.
