red dot scoped 12 guage barrel that i shortened from 28 to 22 and duracoated. guy on youtube gave me the idea. bought the clamp less than 10$ and 100$ for the Sig red dot romeo 5. another 20$ for the spare synthetic forearm as i didnt want to mess with the original. i had to use a flat file a notch where the clamp sits around in. covered the notched area with some lengths of plastic picatinny rail. i think its a slick set up.the rail clamp sits behind and against the barrel screw stud so it wont slide anywhere with recoil. be nice if a company made this type forearm and rail clamp in a set for purchase already but it wasnt too bad to make.with all the naked single shot barrels out there i think it would be a big seller.
