The HERA Arms CQR Buttstock GEN.2 can only fit a rifle length A2 buffer tube. A carbine length Mil-spec or commercial tube does not fit due to dimensional differences between them and A2 tubes.
To fit the HERA Arms CQR Buttstock GEN.2 you would have to replace your buffer tube and buffer system with a rifle length A2 buffer tube. Once replaced, this stock will fit and function as intended. You can find an A2 buffer tube kit by using the link below:
