Haloson507c cut
Had my gen 5 glock slide cut for a 507c optic. The cut was perfect I have had it on now since November and the optic has not moved/screws have not backed out. I have put around 2-3k rounds through it since the install. I did not like the silver screws that was sent with the finished slide so I used the black ones that came with the optic. I would definitely use this company again. A+
