An amazing rail - Battle Arms Development Rigidrail M-Lok Handguard

I originally bought the 13.7" for use with my B.A.D. billet upper and lower and 14.5" barrel. It is a great quality and amazingly light. When I was building my 20" rifle, I couldn't find a rail longer than 15" that I liked, so the obvious move was to swap out my 14.5" barrel for the 20" and buy the 17" B.A.D. rail. Both are amazingly light and rigid, and look great. They have built in QD holes, a bipod mount, and Mlok slots at 45* at the end of the barrel, perfect for mounting WML's. The barrel nut and rail lock system are also lightweight and solid.
