  1. Need adjustability? Can't go wrong with this.
    I’m glad I bought this.
    I was using the standard A2 grip for the longest time and finally got sick of it not fitting nice.
    I didn’t want to try out a whole bunch of different grips to see what fit, so I bought this and I’m so happy with it.

    Lots of adjustability with it, it looks good and feels great.

    It DOES come with its own grip screw (it said it didn’t when I first purchased)

    I did end up breaking one of the tabs on one of the backstraps, so install the grip WITHOUT the backstrap, and don’t reef it on like I did.
    This may not be an issue on proper mill spec receivers. Mine is a Norinco.

  2. Great Grip
    So much better than a mil-spec grip. The adjustability is perfect when looking for that customized perfect grip. The storage space options are handy too.

The MIAD (MIssion ADaptable) GEN 1.1 Grip is a drop-in replacement for the standard AR15/AR10 grip, now available in two dedicated configurations to fit most receivers. It is designed to improve ergonomics with interchangeable front and rear straps for personalized hand fit, an aggressive texture for positive weapon control, and is compatible with all Magpul grip cores to adapt to various storage needs.

This update to the original MIAD has improved strap retention and also comes standard with the newest grip core that holds an included 1/2 oz. lubrication bottle.

Two sizes are available- this TYPE 1 Kit (MAG-520) fits most 5.56x45 and 7.62x51 AR receivers and the TYPE 2 Kit (MAG-521) which is required for some 7.62x51 size receivers*.


  • MIAD GEN 1.1 Grip
  • Height, receiver to bottom: 4.0 in.
  • Thickness, max: 1.2 in.

NOTE: This TYPE 1 Kit fits all AR15/M4's as well as many 7.62x51 variants such as the Aero Precision M5 308, CMMG MK3, CORE Rifle Systems CORE30, HK 417/MR762A1, LWRCI REPR, Mega Arms MATEN, POF P-308, Ruger SR-762, and SIG716.
The TYPE 2 Kit uses taller backstraps for optimized fit with certain 7.62x51 receivers such as the Armalite AR-10A/B/T, DPMS LR308, KAC SR25, LaRue OBR, LMT .308 MWS, Palmetto PA10, and S&W M&P10.
In general, the TYPE 1 Kit will fit most all 7.62x51 AR lower receivers but there may or may not be a gap between the backstrap's 'beavertail' and the receiver. This gap is purely aesthetic and will not affect function.
