This upper has everything for your Ruger MK IV. Not only is it extremely light and well balanced, the accuracy is even better. How does Volquartsen do it? They use a hard anodized, machined Type III aluminum receiver to reduce weight and then fit it with a stainless steel match barrel.
The Mamba-X LLV Competition Upper differs from other lightweight designs. Despite their light weight, they feature a stainless steel chamber to withstand the rigors of shooting.
Features:
Black anodized aluminum
Stainless match barrel
The Upper is available in the following configurations:
Threaded barrel or single port compensator
4.5" or 6" barrel
Target Sights or without rear sight / front sight for retrofitting your own sights.
The Target Sights do not include fiber optic inserts.
Suitable for all Ruger Mark IV and Mark IV 22/45 models
