TAG Innovations, also known as Airsoft Pyrotechnics, have their products on display at the SHOT Show 2017band they have an stand alone or M4 mounted grenade launcher to better launch their pyros. Ross of Airsoft Megastore visits them to learn more about this... "We stopped by and talked with one of the owners of Airsoft Pyrotechnics, TAG, with two of their brand new grenade launchers. The one is able to attach to your M4, and it sounds like they upped their range as well. The other is a stand alone launcher, that also features the option of adding two C02 canisters to increase your shots down range. The really nice thing about this platform is that it uses C02 as the main propellant, and we all know the consistency of C02 during cold weather. So be sure to stay tuned to our website, and let us know in the comments below your thoughts!"
