An apparatus 10 is provided for initially slowing a backwards extraction movement of a bolt group 12 of a weapon which moves backward automatically after firing and against a force of a return drive spring 14. The apparatus includes first and second longitudinal members 16, 30 having respective distal ends and proximal ends. A mounting mechanism is provided for mounting the first and second members for longitudinal movement of the first member relative to the second member and adjacent the drive spring, with the drive spring urging the first and second members apart and against the bolt group. A retarding mechanism 36 is provided for retarding an initial backwards movement of the first proximal end relative to the second distal end, and for allowing a relatively free further backwards movement of the first proximal end relative to the second distal end as the bolt group moves backwards after firing.
