The addition of a slip-in weight to the carrier slows the action cycling which keeps the rifle locked a little longer. The result is much better brass life, fewer pressure problems and greater flexibility in velocities, especially with the heavier bullets used in High Power Rifle competition. A flange, 0.080" thick, reduces the distance the carrier must return to engage the bolt stop which extends the life of this part. Instructions included.

This forces the bolt to remain locked for a fraction of a second longer
