BCM RAIDER-M13 Rail Black Anodized 13.00" M-LOK Free-Floating Style Made of Aluminum for AR-Platform. Most critically the introduction of the MIL-STD-1913 rail AKA the Picatinny rail. The rail has standardized the employment of red dots variable power scopes thermal electro-optics white lights and lasers to allow for positive identification de-escalation and ultimately more accurate engagement in a no-fail encounter. This capability did not come without a cost. Added together these life saving enhancements added significant weight to the individual platform. Modular rails were offered by BCM with the Jack Carbine in 2012 and then with the Companys ultra-light KMR (KeyMod Rail System) in 2014. However for end users in uncertain and complex environments where stacking these enhancements are required additional considerations must be weighted.
