I am another happy owner, Put about 400 rounds during my first session from the 500 pack of ****** Thunderbolts I had sitting around to see how the rifle would do with cheap ammo (I wanted to see if I could get it to jam, had to put it through its paces heh). No cleaning during that session other than a couple quick barrel swabs and still no jams even with the dirty ammo. Going to stick with my Yellow Jackets and Mini Mags now that I'm done testing the reliability.
