The Mini Mamba is the lightest, most compact Mamba package we offer. It features an overall length under 8". It all starts with a 3" LLV Competition Upper. This upper features a stainless steel barrel (with stainless steel, laser hardened breech) housed in an aluminum shroud. This design provides match grade accuracy in a lightweight package. An integral Picatinny rail on top and bottom is standard. Our Competition Bolt with DLC Coating is ensures smooth operation and function, whether its 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 to provide 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.
