Just picked up a SW5K in really nice shape.
Upon disassembly, the bolt carrier appears to be a single piece casting rather than a 2-3 piece welded assembly. Also, the front of the carrier on the tube section appears to have been welded at one time.
Can anyone provide any feedback/thougths on the above?
Any one have experience with the POF MP5K bolt carriers? The SW bolt carrier works OK, but the POF seems more "solid". Does the POF bolt carrier have the tungsten filling?
