CANCOLTM422

There is another option without having to remove the Front Sight. I also got the Umarex Colt M4 Carbine (the OPS model was not available). I had my dealer change the stock handguards with the F.A.B. Defense M4 Aluminum Quad Rail (carbine lenght M4 replacement forend rail system) and it fit like a glove. In fact with this quad rail the rifle looks more like an actual COLT M4 Carbine (with quad rails) than the OPS model.

I just received my Umarex Colt M4 Carbine today from Wolverine Supplies. Since they did not have the OPS model I had them install a F.A.B. Defense M4 Aluminum Quad Rail to replace the stock handguard. The rifle looks great with the quad rail on it, plus I also got an Eotech 512. With this setup it pairs off nicely with my LMT CQB MRP Defender AR15. ;D
