Special Operations Carbine

The Daniel Defense Custom M4A1 includes the core components and configuration never before available outside a custom shop.



The major components that make this a SOPMOD variant are the Daniel Defense RIS II FDE handguard and the B5 SOPMOD Coyote Tan stock assembly. Daniel Defense has also foregone the laser markings on the receiver, and used a standard GI ejection port cover and A2 grip.

Action: Direct Impingement

Caliber: 5.56

Length: 32.25"-35.8"

The Daniel Defense Custom M4A1 features a heavy, carbine length M4 barrel and a pinned and welded A2 flash hider to meet the legal 16-inch requirement.



The chrome bore and chamber on the hammer forged barrel will provide a long service life. The gas system includes the proper Mk12 gas block underneath the RIS II handguard.
