Designed it for a browning pump action,wel suitable for airsoft as the dimensions are very similar, the light is the one flooded on ebay, chinese made led hand lamp (with the mode hi low beam and strobe) modified with a pad switch becomes a cheap tac light (to be honest,use a surefire device if you want a decent tac light) but as a budget,this works just fine. print 2 of them and bolt together,if you want it withoud rounded edges le me know.
