What I like about it is you don't have to run full autoish with it. It can be controled to 1, 2 and 3 round bursts with a little practice. I have had fun bumpfiring from the hip with my SKS and cheap ammo from time to time. Of course any kind of accuracy was impossible and you really understood the phrase "pray and spray". I had the opportunity to shoot a friends AR with one installed. I brought five 30 round magazines to play with and play I did. The first three went fast and dang it was fun but what was so great I could actually aim while shooting and group very well. Then I tried the selective 1, 2 and 3 round fire but the best I could get was 4 or 5. Still I enjoyed the session and I need much more practice . Instead of buying one I will just use my buddies from time to time.......and conserve my ammo!!!
