Tectonic Innovations

Tectonic Innovations is a small British maker based in Croft, Leicestershire, best known for the Quake 8-way impact grenade. The Quake is a reusable airsoft grenade built from stainless steel and aircraft-grade aluminium. A plunger drives a firing pin into a 209 shotgun primer when the grenade lands, and the player turns the base to the next of its eight chambers to throw it again. It comes in an anodised colour range, bronze and custom designs. The company also sells Quake and Neutron spare parts such as head units, hammer springs, firing pins, locking pins and base plates, Neutron rimfire inserts and glow sticks, and packs of Cheddite and Fiocchi 209 primers to feed them. Its newest product is the Hurricane HPA engine, a V2 drop-in kit for M4 gearboxes taken on pre-order. Tectonic sells direct from its web shop and to trade, and UK and European airsoft shops stock the Quake.
