BCM Gunfighter AR-15 Charging Handle Mod 4B - Medium Latch

BCM Gunfighter AR-15 Charging Handle Mod 4B – Medium Latch

The BCM Gunfighter AR-15 Charging Handle Mod 4B – Medium Latch offers improved handling and mechanical durability in a clean, right-hand-only configuration. Designed for shooters who want more leverage than a mil-spec unit without the bulk of oversized latches, the Mod 4B strikes a perfect balance between performance and low-profile functionality.

The medium latch extends approximately 0.91″ beyond the body of the handle, giving you faster, more confident access when charging the rifle or clearing malfunctions. Its compact footprint stays out of the way of optics and gear, making it ideal for duty use, competition, or defensive builds where snag-resistance and speed matter.

Machined from high-strength 7075-T6 aluminum and finished with a MIL-SPEC Type III hardcoat anodizing, the Mod 4B is engineered to handle harsh conditions and heavy use. BCM’s refined latch geometry helps redirect charging force into the body of the handle, minimizing stress on the roll pin and preserving the integrity of the upper receiver over time.

While not ambidextrous, this right-hand-only design provides excellent function and access for traditional charging techniques, especially when combined with rail-mounted optics or in low-light conditions. The streamlined shape makes it glove-friendly and highly effective without overcomplicating your setup.

Compatible with all MIL-SPEC AR-15 upper receivers chambered in 5.56 NATO, .223 Remington, and similar calibers, the BCM Mod 4B installs quickly and provides a durable upgrade trusted by professionals and civilian shooters alike.
