So I ordered the wrong brake for my M1A and wanted to offer a trade before I reorder a new one.
Looking to trade a surefire MB762SS01 for a surefire FH762KM14. mine is still in the packaging and has all the color coded shims and mounting instructions.

heres the surefire site with the muzzle brake im offering
