Brownells has paired the Daniel Defense Stripped M4A1 Upper Receiver with the ever-popular LAW Tactical Folding Stock Adapter! The Daniel Defense upper is finished in the Desert Dark Color they are known for and we have added the option of either a black or flat dark earth folding stock adapter.

The Daniel Defense M4A1 SOCOM Block II Upper Receiver has been designed for those looking to match the specs and performance on the M4A1 SOCOM Block II carbines used by troops during Operations Iraqi Freedom and Enduring Freedom. The Daniel Defense M4A1 SOCOM Block II Upper Receiver features a quad-rail handguard equipped with a Picatinny-compatible rail sections. The barrel is cold hammer forged from mil-spec chrome-moly vanadium steel and features a SOCOM, heavy profile, with a chrome-lined interior, matching military-style barrels with the same construction. The gas block is a Daniel Defense pinned low profile block, the same as the current generation provided to SOCOM.

  • Made from 7075-T6 aluminum
  • Barrel length: 14.5 inches
  • Twist rate: 1:7
  • Does not include BCG, charging handle or flash hider

The Daniel Defense M4A1 SOCOM Block II Upper Receiver features a flat dark earth anodized finish. Available with black or flat dark earth LAW Tactical Folder.

Law Tactical's steel adapter enables installation of a folding stock on any AR-15 to create a smaller-profile rifle for easy deployment from a vehicle or transport in non-permissive environments. Works with standard gas impingement OR gas piston system. Accepts A2, mil-spec M4-style, and commercial carbine receiver extension tube and almost any stock that fits them. Compatible with all standard bolt carrier groups, including full-auto and .308 size. Single-button operation for quick folding and unfolding and steel locking latch keeps stock securely in place when extended. Gen3-M has a lowered hinge to avoid interference when charging the weapon, and a setscrew keeps the adapter securely affixed to the receiver. Hinge tension is adjustable so you can choose how stiff the folding mechanism is. Includes special bolt carrier extension (no tools to install/remove). Current version utilizes standard buffer retaining pin and spring. Stock adapters feature a DLC coating, except for the Olive Drab Green which has a Cerakote finish.

Will only work with compatible Centerfire and Mil-Spec carriers, or compatible AR 9mm Bolts.

SPECS: Machined 4140 steel, DLC finish, matte black. Adds 1.3" (3.4cm) to length of pull. 8.5 oz. (241g) wt. Do not fire rifle with stock folded.
