From the manufacturer

The Geissele Super Duty Complete AR-15 Upper Receiver comes with more options than a 1970s Cadillac, including a Surefire Closed-Tine Flash Hider, Geissele's Super Modular Rail M-LOKA(R) handguard, and their ambidextrous Airborne charging handle. A tooth in the top rear of the SMR handguard mates with a notch in the upper receiver to prevent unwanted handguard rotation that could compromise optic and/or backup sight alignment. Inside, the Super Duty Upper Receiver has Geissele's Reliability Enhanced Bolt Carrier Group (REBCG). The carrier is machined from extra-hard 8620 carbon steel with extended upper rails to ensure ultra-reliable feeding. (The chrome-lined gas key is, of Mfg: Geissele Automatics
