ArmaLite DEF15 M-15 Rifle 223/5.56 NATO 16" Barrel 30+1 Black

The ArmaLite DEF15 M-15 delivers proven reliability in a defensive sporting rifle configuration that handles both range training and home protection scenarios. This 223 Rem/5.56 NATO platform combines ArmaLite's decades of engineering experience with modern manufacturing standards. The rifle ships ready for immediate use with standard capacity magazines and accepts most AR-15 compatible accessories.

What Makes This Different

The DEF15 features ArmaLite's chrome moly vanadium steel barrel construction, which provides superior accuracy retention compared to standard carbon steel barrels. The hard coat anodized receiver finish resists corrosion and wear better than basic mil-spec coatings. The 6-position collapsible stock adjusts from 10.75" to 14.5" length of pull, accommodating different body types and shooting positions more effectively than fixed-length alternatives.

Key Features

• 16" chrome moly vanadium barrel with 1:9 twist rate for optimal bullet stabilization
• Hard coat anodized aluminum receivers with Type III finish for enhanced durability
• 6-position collapsible stock adjusts for length of pull from 10.75" to 14.5"
• Standard AR-15 magazine compatibility accepts most 5.56/.223 magazines
• Flat-top receiver with full-length Picatinny rail for optics mounting
• A2-style flash hider reduces muzzle flash and protects crown threads
• Standard trigger group with approximately 6.5-pound pull weight

The DEF15 maintains consistent accuracy across temperature ranges and extended firing sessions. The chrome moly vanadium barrel construction handles rapid-fire strings without significant point-of-impact shift. Law enforcement agencies and competitive shooters report reliable function with both brass and steel-cased ammunition. The rifle cycles standard 55-grain ball ammunition as well as heavier 77-grain match loads.
