Black Spider Optics
The Black Spider Optics N1 w/ bubble level one piece scope mount is designed for AR-15 rifle and scope which feature a 30mm tube diameter. The primary benefit of this particular mount is the fact that it has a bubble level which is very helpful when trying to precisely shoot at long range distances. Making sure that your bore and scope are shooting from a level position is one of the most overlooked aspects of precision long range shooting. The mount is made from high quality CNC machined aluminum with a hard coat anodized finish. The BSO-N1-L mount features a cantilever or forward offset which is ideal especially for AR-15 and other similar sporting rifle platforms. The mount will easily attach to any Mil-STD-1913 picatinny rail.
