Make ur 30 round ak74 magazine into a 38/7 round ak74 magazine for no reason! This started out as a +5 but for some reason it became a +8/7 for 556 and idk a +8/9 or something for 545. The hole in the front is for a .156in/4mm hex key cause for some reason I have 4 of them lying around :/ Ive tested it on a handful of mags at the range so far and seems to be solid :3 lemme know what you think of it >. <
