In December 2006 I ordered a Bushmaster .22 conversion for my B/M lower receiver. It took two months and several requests for assistance (which were promtly and politely answered) before I received the conversion. Due to weather, I didn't get to shoot the piece until late March. Immediately upon receipt, I cleaned the conversion, and examined the it and the lower for anything that might cause a malfuntion (I'm a retired Marine MasterGunnerySergeant, and I do know how to check a weapon for serviceability). My experience is the conversion makes an adequate $435 single shot plinker. Using B/M recommended ammo, the first misfeed occurred two rounds into the first mag load. I reloaded, tried again, and was only able to chamber and fire the first round. After about five attempts, I field-stripped and cleaned the mag, at which time a small tip at the mag base broke. I emailed B/M tech, and received no answer. I got hold of a tech, by landline; he had no suggestions, and told me to send the mag to AZ, where it was manufactured. To date, no replacement has been rec'd. As an aside, I ordered a spare mag, with the conversion, and haven't rec'd that, yet, either. Panzer sends
