Competition shooters are always looking for that "little something" that will save even a fraction of a second. The Black Mamba-X and its multiple hole mounting locations will do just that. Keeping the red dot mounted as low to the bore-axis as possible makes for faster sight acquisition and there is no better way to do that than to mount the red dot directly to the upper. The Black Mamba-X is built using our LLV-4X 4.5" Competition Upper that features an integrally machined universal red dot mount. The Black Mamba-X is a competition ready pistol in a push-button takedown configuration. Nothing strikes with the speed and agility of the Black Mamba. It combines features from the Volquartsen Scorpion 22 LR Target Pistol along with the push-button takedown functionality of the Ruger® MK IV™ 22/45 frame. The Black Mamba-X comes standard with: A ½ x 28 threaded stainless steel 4.5” barrel with stainless steel laser-hardened breech within a type III hard anodized aluminum shroud Volquartsen Accurizing Kit for a 2.25 lb trigger pull DLC coated Volquartsen Competition Bolt Volquartsen Single-Port Compensator Specs Product Number VF4M-X Approximate weight 1lb 12oz UPC Magazine Capacity 10 Trigger Weight 2.25lb Twist Rate 1:16 Muzzle Threads 1/2x28 Overall Length 11.0" Included Items 2 Magazines Configuration Length 4.5 inches Grips Hogue Grips Threads/Comp Choice Compensator Threads/Comp ?
