Midwest Industries’ MI SCAR Rail Extension has your M1 SCAR rifle barrel covered—and then some. Weighing a minute 8 ounces, the SCAR Rail Extension adds 6 inches of valuable quad-Picatinny real estate to your 16 or 17 Series SCAR rifle. In addition to the added rail, the Rail Extension provides users with two anti-rotation QD sockets for push button swivels. Made from light, but durable 6061 aluminum, the Rail Extension is hard-coat anodized for a lifetime of use. It comes available in black or flat dark earth (midwestindustriesinc.com).
