My hk91 and Cetme lock when pulled fwd. the 9MM just slides back and forth. shoots fine just courious The rifle calibers have a different design on the carrier in that there is an additional piece on the left side of the carrier that is a spring loaded lever. It puts pressure against the bolt head and can lock in place if you push the head into the battery position. Check it out since you have both types. The subgun design (MP5s of different calibers) do not incorporate that "feature" so that's why they freely rotate and move in and out. |
