This is a firearm — here's how it works
- Order online. Pay in full; we ship it from our warehouse into the shop.
- We receive it. The firearm ships to us (or your chosen FFL) — never to your door.
- DROS & the 10-day wait. California background check and the mandatory 10-day waiting period begin at the counter.
- Pick up & transfer. Bring valid ID and required documents; we complete the compliant transfer.
Description
The MK12 is constructed around an 18-inch Stainless Steel barrel with a chamber created during the Cold Hammer Forging process, which ensures the most precise alignment of the chamber to the bore possible. This, along with being salt bath nitride finished, equates to unprecedented accuracy and durability. The MK12 barrel is engineered with a rifle-length direct impingement gas system and utilizes the MK12 gas block, which is built to Crane Specifications for USSOCOM. Its gas block is precision CNC machined from 416 stainless steel and Black Oxide Coated. The rifle is fed with a M16 profile bolt carrier group and uses a Vltor Mod 4 charging handle for ease of operation. Its upper receiver is equipped with a free floating DDM4 Rail 12.0 quad rail for allowing your choice of optics and accessories and is finished off with a Daniel Defense Improved Flash Suppressor. It is equipped it with the Geissele SSA1 2-Stage Trigger to give the marksman an advantage delivering precise fire to the target. It is also furnished with a rugged and comfortable Daniel Defense Buttstock and Pistol grip.
