The triple Mag retention insert combines the excellent retention capabilities of elastic with the added security of a pull tab for us on airborne operations.
With 3 x compartments that fit standard steel mags or PMAGS, hook velcro on the front and back allows the insert to be fastened in either the front/rear pouch of the M.M.C.R or one in each allowing you up to 6 mags.
3" Tall x 9" Wide
Not only was it fast but was exactly what I expected. Works flawlessly with my Kang pouch and various other rigs. Highly recommend
