The Rearden PRS in 3/4×20 is a muzzle brake from Rearden Manufacturing designed for barrels larger than .750 inch, though it works fine on smaller profiles as well. It is machined from 17-4 PH stainless steel in H900 condition and finished in black nitride. The PRS is Atlas and Atlas XL compatible and Plan B compatible, so it doubles as a suppressor mount. At 2.25 inches overall it adds 1.625 inches of length and weighs about 2.77 ounces in this thread. This listing is the 3/4×20 pitch, which is the one that sets it apart from the 3/4×24.
