Beautiful fit and finish
Great little package. Love the aggressive look. Holosun 507C mounted no problem. Fit and finish seem perfect. Can't beat it for the price.

MDX LF19 Kit
I really like this slide kit, Unfortunately it got 4 stars because the recoil spring guide rod is plastic. I bought one a few months ago and that one was stainless steel (looks way better). but I would buy again, but probably replace the guide rod. Thanks!
