The BCM Tri Rail is an authentic replica of an accessory in use by Canadian forces on their standard service rifles. It represents a simple, rugged, and lightweight solution for those shooters who want to mount accessories such as weaponlights while still using the standard issue handguard. It is made from 6061 aluminum and is hardcoat anodized. It is designed to fit around a .750 diameter barrel under a Milspec front sight base.
Weight of the BCM tri rail is 4 ounces.
