Purchased this to hold a M18 Smoke Grenade. It fits, but just barely. The quality is top notch, which I've come to expect from ATS.
Large Flashbang Pouch
The ATS Large Flashbang Pouch is very cleverly named. It holds, in fact, a single large flash bang munition, like the Defense Technology #25 or similar munitions. The lid is adjustable for different height munitions, and is removable as well. There is an elastic band around the body of the pouch to provide retention.
The body of the pouch is 4 1/2 inches tall and about 3 inches wide. It uses two channels and four rows of MOLLE space. As all ATS-made stuff is, it's covered by our lifetime warranty against defects in manufacturing, in materials and/or workmanship.
