I removed the air restrictors in mine also, and it went kaput. I did everything by the book and tried many things to get it to work. I think it doesn't work due to the plunger/barrel not functioning together properly. The end of the plunger where the air comes out, rubs on the rotating barrels, thus not allowing it to rotate. If I force te barrel to rotate by hand it shoots worse than stock. The maverick seems to have intricate internals that can be upset relatively easily. I may try to mod another one, but I don't think its totally necessary as I use it as an indoor gun, and its stock range of about 25 feet is sufficient for indoor use, IMO.
