Daniel Defense Ambush Firearms A11 V680

The Daniel Defense Ambush Firearms A11 V680 is a semi-automatic tactical rifle chambered in 6.8mm Rem. SPC. Daniel Defense specializes in making M4-style carbines and accessories. The Ambush is one of two carbines Daniel Defense makes that’s chambered in 6.8 SPC.

What’s different about the Ambush, besides its cartridge, is its free-floating modular tube handguards as opposed to quad rails. The tube has a single Picatinny rail running along the top for easy mounting of optics or accessories. And it lacks vertical fore-grip.

It has a mid-length gas operating system, so propellant gases are caught in a tube near the muzzle, the tube guides it back to the bolt and then catches in another tube on the bolt. When the gas is caught, it drives the bolt back. This delays recoil until the projectile has left the bore. Mid-length means that the gas is caught after a medium distance in the barrel, so less pressure is used to push the bolt back (compared to the short length gas system).

Features include a chrome lined bore, a MagPul buttstock that’s lightweight and adjustable, a cold hammer forged barrel, so a machine carefully carved the grooves in the bore. This process produces accurate and durable rifling. And it has a sling swivel attachment points, so users can attach a combat sling, which allows them to sling it while carrying it at the ready.

The cartridge 6.8mm Rem. SPC is a newer cartridge and falls between 5.56mm and 7.62mm.

Daniel Defense recommends the Ambush for military, law enforcement or personal security.
