Rubber City Armory Low Mass Bolt Carrier Group With Adjustable Gas Key For AR15 Style 5.56 / .223 Rifles

I've heard of adjustable gas blocks, but never heard of an adjustable gas key?  What's an adjustable gas key?
The Adjustable Gas Key (AGK) operates on the same premise as an adjustable gas block, but the AGK works at the opposite end. Instead of controlling the gas at the gas port (via an adjustable gas block), the AGK controls or more appropriately "limits" the gas at the gas key, on the more accessible bolt carrier. Having the gas adjustment at the bolt carrier is much easier than adjusting gas flow at the gas block, which may require removal of the handguards depending upon the make.

It's a very cool idea, and it works! The AGK is ideal for someone running a lightweight system as it slows down the bolt and softens its subsequent recoil impulse. The Rubber City Armory Low Mass Bolt Carrier Group is ideal for the 3 gun shooter or for ANY shooter who wants to reduce muzzle movement between shots.

Bolt Carrier: made from high-grade 8620 steel and finished with H&M's Black Nitride+ treatment, this carrier is is much lighter than the standard M16 carrier. Weighing in at just over 8.9 ounces the RCA competition carrier makes a noticeable difference. Carrier comes complete with nitrided stainless steel billet gas key, nitrided 17-4 stainless steel firing pin, and their enhanced 9310 nitrided bolt.
Instructions Included

Adjustable Gas Key: enhances performance of low mass and standard mass GI systems without unnecessary dissassembly. Gas flow is adjusted and maintained at the carrier with 2 set screws. One to adjust gas flow and one to lock it in place. Made from pre-hardened 4140 steel 28-32RC with radiused corners reducing sharp edges.
