Overview
A 1-6x24mm second focal plane rifle scope built for AR-platform rifles, with an illuminated MSR BDC-6 reticle offering 11 brightness settings. It ships with SIG's Alpha-MSR one-piece aluminum cantilever mount and flip-back lens covers, and the tube is nitrogen-purged for waterproof, fogproof use.
The BDC-6 reticle hash marks are tuned for flat-shooting rounds like 5.56 and .308, so holdovers on other calibers take extra work to learn.
