This is a high quality free float handgaurd manufactured in the USA by CMMG. Made of 6061 T6 type II anodized aluminum, it is light weight and durable. With a continuous picatinny rail running the length of the top and MLOK slots at the 3, 6, and 9 o'clock positions, shooters can accessories as much or as little as they like. We reccommend pairing this handguard with any of our rifle length barrels.
