Volquartsen Firearms Black Mamba DBG Semi-Automatic Pistol .22 Long Rifle 4.5" Barrel (1)-10Rd Magazine Black Cerakote & Gold Finish The Black Mamba combines features from our Scorpion .22 LR Target Pistol along with the push button takedown functionality of the Ruger MK IV platform. It all starts with our LLV Competition Upper. Available in a 4.5'' barrel length, it features a stainless steel barrel (with stainless steel breech) housed in an aluminum shroud. This design provides match grade accuracy in a lightweight package. Each Black Mamba features a threaded muzzle with our single-port comp installed. Our Competition Bolt with DLC Coating is ensures smooth operation and functioning whether it's a day of plinking at the range or competing at the highest level. The Black Mamba build utilizes a polymer Ruger MK IV 22/45 frame that has been retrofitted with our Accurizing Kit providing a crisp, clean 2.25 lb trigger pull. The frame has also been fitted with our magazine release that, when used in conjunction with our magazine base pads (included standard), eliminates feeding issues. This is accomplished by raising the magazine's position in the frame, allowing the bolt to more positively engage each round as it feeds.
