Details
The evolution of the SPR comes home to Daniel Defense in the MK12. This firearm 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 DLC 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. The MK12 gas block is precision CNC machined from 416 stainless steel and Black Oxide Coated. The new independently ambi GRIP-N-RIP Charging Handle accommodates left- and right-handed shooters and is engineered for suppressed fire, with anti-gas features that redirect gas flow upward and away from the face and operator. The 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. The MK12 was designed from the ground up to be a precision rifle, therefore it required certain refinements. We equipped it with the Geissele SSA 2-Stage Trigger to give the marksman an advantage delivering precise fire to the target.

Awesome buildGot last upper from midway for my roomate. Built his preban lower from essential arms with a custom polished mil spec trigger group . Shoots sub 1/2” groups with a nice vortex 1-6 with just the 55gr ball so far once ammo is back we will test with some of that nice mark 262 but ball is shooting great. I thought he should have went fixed stock but the dd collapsible is very solid. The grip is very comfortable. I still think a2 stock on this bad boy though. Running the stock bcg with guiselle braided spring feels awesome. Stock a2 dd flash hider is better in all ways than cheap a2 one. Awesome looking barrel thick and impressive finish. The balance is front heavy but very light overall. A nice lightweight ar optic would be better than heavy vortex. Maybe an acog 4x. Sweet rig either way...

Fantastic ProductWow! Owning this MK12 Is the best gun purchase I have ever made. Got on the range with my Red Dot and 3x Magnifier and was in perfect zero immediately. Love the ease and smoothness of the trigger and balance.
Thank you Daniel Defense for building such a precision rifle. More than worth every dollar I paid.Posted on
