Magpul back-up sight on Madbull Noveske rail
Hi all,
I have a Madbull Noveske 12" rail on my PTW, and I brought the Magpul PTS back-up sight set yeaterday. I tried to slide th Magpul front sight onto my rail, but it cannot go in, seems like it is too small to fit into the rail. I have seen pictures of other c-hing with the same rail got it to fit, can anyone tell me how to?
Thank you very mcuh.
