Engineered for 5.56mm NATO, this AR-15 platform rifle features a 14.5″ pinned and welded barrel and a 12.5″ RIS III handguard, delivering unmatched performance for enthusiasts, competitors, and professionals. Its Flat Dark Earth (FDE) finish ensures a sleek, durable aesthetic.

Key Features

Precision Barrel and Gas System

The 14.5″ cold hammer-forged barrel, made from Chrome Moly Vanadium steel, features a 1:7 twist and a government profile. Chrome-lined and mil-spec heavy phosphate coated, it ensures durability and accuracy. The mid-length gas system, paired with a pinned low-profile gas block, optimizes reliability and reduces recoil, outperforming competitors like BCM or Aero Precision in smooth operation.

Advanced RIS III Handguard

The 12.5″ Daniel Defense RIS III handguard utilizes a patented 6-bolt bolt-up system and M-LOK mounting for lightweight accessory customization. CNC machined from 6061-T6 aluminum with an FDE finish, it provides superior strength and versatility compared to standard quad-rail systems found on rifles from Palmetto State Armory or Ruger.

Ambidextrous Controls and Enhanced Ergonomics

The proprietary lower receiver includes a flared magazine well and fully ambidextrous controls, catering to both left- and right-handed shooters. The Daniel Defense buttstock and pistol grip, featuring soft-touch overmolding, enhance comfort and control, surpassing basic polymer grips on entry-level ARs from brands like Smith & Wesson.

Reliable Bolt Carrier Group

The M16-profile bolt carrier group is mil-spec MP tested, chrome-lined, and properly staked for rugged dependability. This ensures consistent performance under demanding conditions, giving it an edge over less rigorously tested components in budget-friendly rifles.

Pinned and Welded Flash Suppressor

The extended Daniel Defense flash suppressor, made from 17-4 PH stainless steel with a salt bath nitride finish, is pinned and welded to meet compliance requirements while minimizing muzzle flash. This design offers better flash suppression than standard A2 flash hiders on competing models.
