Does anybody else have complete feeding issues w KWA K120 mid cap magazines? I bought a whole set of K120s and neither my Krytac nor my other m4 feeds w them. The mk18 has a ProWin hopup unit and the krytac had the standard krytac hopup so i’m not too sure if it’s an issue w the mag wells, the hopup units, or the mag releases or what the issue could be here. The K120s don’t have an issue feeding in any of my other M4’s so if any of y’all have any idea or solutions other than electrical taping each individual magazine lmk. Thank y’all!
