This device is a highly effective and smart platform for your TAG-ML36 grenade launcher. The purpose of this chassis is not only to make the TAG-ML36 independent of your primary weapon, but also to extend aiming possibilities by adding a red-dot, optical scope or any other special aiming device on multiple 20mm "Picattiny" rails. There's another great feature that may be added as an add-on to this platform - the additional chamber for 2 x 12g CO2 tanks in order to extend a number of shots-per-load up to 20.
