This MK2-12.5 Short Stroke Piston Rifle is chambered in 5.56 NATO.
Built on a 12.5" light weight contour 416R stainless steel barrel with a 1/2x28 thread pitch.
The MK2-12.5 runs a patented "Bleed Off" gas piston system. Built gas pressure within the block is reduced only to the amount required to drive/cycle the carrier. All remaining gas is bled out of the block allowing the system to run cleaner and noticeably cooler. This will reduce your weapons recoil and eliminate blow back while running suppressed. This block is fully adjustable up to 30 positions allowing you to fine tune your system unlike most systems which only allows 3-4 positions.
The carrier is coated in Titanium Nitride while the bolt is coated in Nitride. Titanium Nitride (TiN) coating is a wear resistant, inert, and reduces friction. Titanium Nitride also reduces galling between sliding components and improves overall life.
This pistol comes equipped with a Law Tactical GEN3 Folder. While the Folder does add cost, it gives you the ability to reduce the overall length while concealing during transportation.
Our pistols run a fully adjustable 45/90 degree short throw safety selector and an extended magazine release to give you that perfect feel. Our charging handle is fully Ambi giving you complete control from either side.
This rifle runs our TYPE-A PMC Two-Stage Trigger. Constructed from pre-hardened 4140 this trigger is coated in Nickel Teflon to fight against friction and to ensure lubricity. The PMC Two-Stage Trigger ships at 1 1/2 reset to 3 1/2 trigger pull.

Training – Physical Preparation

"This advice has less to do with the rifle and more to do with the operator.  Don’t forget the importance of breaking a sweat and elevating your heartrate every now and again.  You may be able to run your rifle like a demon on a static range, but if you have perpetual meat sweats and get winded after a flight of stairs, then don’t expect your shooting abilities to hold up when the time counts.  PT doesn’t have to be fancy and you don’t need to spend a fortune.  Start with an old duffel bag and fill it with enough sand to make it taxing to pick up off the ground.  Now take that bag and carry it for a distance.  Pick it up off the ground, load it to your shoulder, set it back down and repeat.  Take it a step further and heave it overhead for reps.  Search Youtube and you will find hundreds of movements to perform with just a simple sand-filled bag.  Bring it to the range and incorporate with live-fire drills…..that’s the pinnacle of fun.  Being in shape will do nothing but improve your shooting abilities."
