I am working through my first build, lower is built, optics purchased, waiting on funds before I buy the upper. Rail covers is one of the few details I havent decided on yet. I see a lot of people using the XTM rail covers, does anyone like the magpul ladder style rail covers? The XTM system seems a little thick, I want to protect my fingers from the exposed rail without adding much size if possible. Please post your favorite rail covers and any rail covers you have had problems with. Wanna kill these ads? We can help!
