Wont fit in psa lower - Mission First Tactical 10 RD Extreme Duty Polymer 7.62 x 51 NATO .308 Winchester AR10 SR25/M110 Magazine

Love the color and the mag grippy thingies on the sides of the mag. , very aggressive texture. Fits in my dpms sass but will not lock into my psa lower, the middle ridge hits on the bottom of the magwell before the release can catch the mag, so bummer , can only use it for certain builds.other wise great feeling mag.
