Submited By: Justin L. on 11/17/2010 Installed on my full metal tsd m190 special forces definately looks beastly especially with the extended clip. Adds a good bit of weight to the gun. Not to hard to install if you already have the metal slide just swap inner and outer barrels (usually one or two screws, the bucking, and a basically microscopic spring be careful not to lose) swap recoil spring guide add the mock flashhider and screw it in with spring into the the new spring guide through the flashhider and your ready to go. Not actually sure of definate range increase but there is some range added and slight accuracy boost (using green gas anyways). Pretty good upgrade. | |
