The EP Carbine Carry Case is a first-party range bag for the Extar EP Series Carbines. This case has four extenal pockets sized for Glock magazines up to a .45 ACP 30 round magazine. Taking customer feedback into consideration, this case has plenty of room for a Carbine with the stock extened, a muzzle device added, an optic on a riser, or however else you would like to configure your EP Series Carbine!
