Just a relic made by G&P Laser Products (you heard me “Laser”). I wonder if they actually used lasers in their manufacturing plant. Conversion front section designed for the Marui G36c, and Marui based designs, to be converted to a G36k, with an extended outer barrel and G36k length hand-guard / fore-grip. $40 (shipped) :) Come with a tuning quad fork, uh, I mean muzzle break, fore-grip retaining pin, and 20mm mounted vertical grip, in addition to the outer barrel extension and hand guard. Trades? Sure. Whatcha got? I love anything E&L or Real Sword. Any parts for those models would be great. I also love Russian.
