ShaDow XPS here enjoying my pictures of various firearms. Love this stuff. Guns and guns and guns. I'll list some favorites but I'll probably not get them all in one go. These are in no specific order.
Colt Model 933 even though it's pretty much an M4 with a shorter barrel
Bushmaster ACR Carbine and all its variants
Smith & Wesson Model 629 custom weighted barrel
Gen AIG Asymmetric Warrior ASW338LM
