Bren Mk 2 Recoil Spring Issues

[Joe H]

Adding a plug in the base of the return spring tube would add more "spring resistance to recoil." I have never had to do this but I've not put large volumes through my Brens.

Wally,

The plug doesn't really add additional resistance it just gives the same resistance as the full stroke FA Bren. The striker prevents the recoiling parts from reaching the rear buffer by the length of the striker so that the return spring is not compressed to its design compressed length. It is short by the length of the striker. The plug allows full return spring compression at the shorter semi stroke. It is particularly important in the design I used since the striker spring is compressed on the return.
