Not for me to handle, but more than there should be. I think most of you are familiar with my Sweetie. I've been plastering the site with enough pictures . She still kicks noticeably more than my friends factory original 20" Saiga. . . The only differences I can discern are that the Saiga weighs slightly more unloaded (with accessories) and has a much heavier recoil spring. I have my suspicions about why my baby jerks and kicks so much but I want to hear some fresh ideas from you fellas! help?
