I used this bolt with a HK low locking piece to replace the one that came with my Vector clone. I used my original bolt carrier. It fit very tight on the locking piece, and in the bolt carrier. The quality is amazing! I am very happy to report that 400 rds now have gone down range with zero malfunctions. Before, the Vector bolt was out of spec and would dig into the round on the magazine. I would recommend this to anyone that is having FTF problems with there clone.
