Hey guys question. I know alot of you have mutiple attachments on your airsoft guns but I am looking for anyone who is willing to sell a holographic sight for a cheap price. or would allow me to borrow a sight for my m4 to use at the next game on the 2nd. Next week to be exact. Or if anyone is willing to give one away. I really need a holographic scope. if you have an extra one and would like to give it away for a good cause id appreciate it. please email me/reply back and thank you. There's a Soldier in all of Us
