- Alloy construction
- 14mm CCW Male threading
- For M4/AR-15 AEGs
Whether you're working on a custom M4 build or you're changing up your setup, the Delta Armory Alloy Outer Barrel for M4/AR-15 AEG is a solid choice. Made from alloy with 14mm CCW male barrel threading at the tip, this outer barrel is offered in 3 length variants: 6.3-inch, 8-inch and 10-inch. Please note, the 6.3" variant measures 5 inches/12.7cm from the collar to the tip of the threads.
Compatibility-wise, this barrel is designed for standard M4 AEG upper receivers and should fit almost every standard M4 AEG on the market. It is not, however, compatible with the M4A1 triangular front sight/gas block, as it lacks the cuts for its mounting pins.
