Had to make it work on real hk mp5 full auto - Sniper MP5 Tri Rails

Had to do some fitting on real Hk MP5 Full Auto in order to fit, but....totally worth for the price, this will do the same job of a $350 Knights RAS fitting a vertical grip or light/laser. Once in place it stays very tight, good deal in the price as well....same part under other name in China (producer) wants more than optics planet price, go figure it out
