BCM MCMR - Best Overall

The BCM MCMR Series of AR-15 handguards offer simple, lightweight and durable design for a 14.5" barrel build. The full length MLOK slots allow the user to mount accessories even in offset positions, which eliminate the need for special offset mounts if mounting from the 9 or 3 o clock positions.

One of the key features of this handguard is its proprietary patented steel barrel but mounting system (US Patent 8904691). This system includes a mechanical index to the 12:00 rail, effectively positioning the mounting hardware to minimize any movement caused by heat generated by rapid firing.

Available for 7", 8", 9", 10", 13" and 15"

For a 14.5" build, a 10" is optimal for weight saving, but not too long. A 13" is just long enough to mount light accessories and grips forward, but also save weight.
