I will be picking up a sig 553lb. The barrel length is 13.6 inches without the flash hider. As such, I'm looking to see if I can find a good flash hider/brake to make it longer than 16 inches so that I don't have to SBR it. The surefire brake is 2.7 inches. I'm not sure that leaves me enough room with the threads in order to have it properly installed. Any suggestions? If you know of any other good brands that are 3 inches, that would definitely do it. Any and all input would be appreciated.
