Hey guys up for grabs there's a 509 Rd acss this has an acss reticle and points amazing but this one is specifically for the Glock pattern handguns comes with a primary arms low mount that's made for the MOS guns this was on a Gen 5 MOS that had roughly about 40 to 50 rounds through it your factory screws should work perfect with this comes with box and documents and Tool battery already installed after taxes and everything this ran me about $440 I'm asking for 325 my loss is your gain would mostly prefer someone local
