Product Description
MCS AR-15 SIDE CHARGING BOLT CARRIER GROUP 5.56/.223/.300/.350
MCS Side Charging BCG is a premium BCG you should add to your next AR-15 build. This BCG is made from durable steel with a finish that improves lubricity, corrosion resistance, and carbon resistance. It takes the classic BCG design and elevates it.
Caliber Compatibility: .223 Rem, 5.56 NATO, .300 BLK, .350 Legend - This BCG is standard for the .223 Rem, 5.56 NATO, .300 Blackout, and .350 LGND calibers, and is interchangeable between all 4 simultaneously. This includes .22 Nosler Chambered AR-15s and .223 Wylde rifles.
Finish: Nitride - Nitriding is a process during manufacturing that diffuses nitrogen into the steel to make a case-hardened surface for improved resistance and strength. A Nitrided BCG typically has a gloss black texture. Nitrided Bolt Carriers have increased resistance to heat, and corrosion.
