RT to RT Pro

[nkatzboy]

Hey folks i'm looking for some information. I just got an RT mag and was wondering what the difference is between it and an RT Pro are. I've had a RT pro rail sitting around for awhile and was wondering if it would bolt straight up or do I need some extra stuff. Also can I just just add a ULE body or do I need some special stuff. Thanks for the help

as long as its not a classic rt the rail will work fine. also as long as both rails are rt the sear will work on both if tis not you need an rt sear for the rt rail
