9mm kits for the M4 series are almost two a penny these days, but this new kit from G&P proves to be something slightly different.
The yet to be released kit from G&P is due for release sometime this month. The kit comes with a 90 round double stacked ‘thermold’ 9mm mag, and a full metal replacement body. The body also features authentic Colt 9mm SMG markings and a new shell deflector. Thanks go out to 14692 in the forums for the heads up.
