In short they suck. I have had no problems with my BG running factory mags. I though this was a cool concept to add more ammo. I figured it was just a new spring and follower. There are a few peices and two springs. I had about 100 rounds to blow through of various stuff. Almost on every mag I had problems with the second to las or last round. On top of the these dumb followers kept tilting or half sliding out the from of the mag. Very crappy. The only mag that ran ok for a bit was a pro mag. But. Again there quality is lacking. It showed once it got dirty. The fallower kept get tick stuck down inside when loading it. So all in all. Stay away from the Mag Gutz kit and pro mag lol. I'm back to factory configuration
No Bueno in a NY reload lol
The many parts to the kit
Again in the factory configuration this gun has been great for me. Minus the dumb laser but I never intended to use it
