Long before I started posting, here or anywhere for that matter I knew that I wanted a MB on my CUR74. I also knew that it had to be permantly attached. What I did was(~1998)put the 4 set screw type, notch the barrel for the screws, and then cover the set screws with a product called Alvin's Lab Metal. It goes in like putty, and can be formed, sanded, etc until dry.

Move forward about 4 years I figured I could knock the "Lab Metal" out, and attach the Romy FSB I picked up from Mbsk1(Thanks bro!). Well 3 hours, umpteen cut off wheels, umteen plus drill bits, cold chisels, hammers... this is what I ended up with..


This stuff was actually harder than the muzzlebreak itself! The red dots are the approx location of the setscrews.
