CMMG 35AFC66 Replacement Magazine 350 Legend 20-Rd AR-15 Black Stainless Steel

The CMMG 35AFC66 is a factory replacement magazine built around the standard AR-15 pattern and chambered specifically for the 350 Legend cartridge. With a 20-round capacity, this stick magazine feeds 350 Legend ammunition reliably through any lower receiver that accepts a standard detachable AR magazine, giving AR-platform shooters more rounds between reloads than the typical low-capacity offerings in this caliber.

The body is formed from durable stainless steel finished in a low-glare black that blends cleanly with most AR-pattern builds. AR-pattern dimensions ensure it drops into any standard AR-15 magazine well, and the internal feed geometry is tuned by CMMG to reliably run 350 Legend ammunition in a dedicated Mk4 upper or a complete factory AR-15 chambered for the cartridge.

As a current-production CMMG part, the 35AFC66 carries the fit and finish expected from one of the most established names in the AR-platform world. The magazine ships ready to drop into a standard AR-pattern lower receiver configured for 350 Legend.
