Took my brand new, store bought Bushie to the range for a little quiet time and the sparks began to fly. The front and rear site were both frozen solid. The jamming continued throught the afternoon. In most cases the action failed to cycle a round in the chamber. Single loading produced magnificent groups, if you like that kind of action. Called Bushmaster this morning, rifle was shipped to the dealer in 1998. they will not cover the shipping, but do request I send them the upper for inspection. Hell fire a couple of more years and it would have been a per-ban.
