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.

PCC

"Considering getting into an AR9?  Here’s some things to consider: 1) A PCC can broaden the scope of your training.  There are many ranges that don’t allow rifles but will allow handgun cartridges.  A PCC also allows you to train on steel much closer than you would with a traditional 5.56 or variant. 2) A shoulder-fired 9mm is a great rifle the whole family can enjoy.  There’s virtually no recoil and they’re much quieter than a traditional AR (even unsuppressed). 3) They’re relatively cheap to run. 4) PCC’s make great home-defense options.  Not saying there’s anything wrong with a 5.56 for home defense.  Just consider your environment, shot ranges, and round performance of possible misses (5.56 compared to 9mm through drywall, studs, and other building materials).  Noise may be another consideration.  If you run suppressed then either platform is no problem, however open muzzle indoors?  The 9mm is less likely to deafen someone. 5) They do not run as dirty.  Since a PCC is a blowback system, you won’t get the same carbon buildup as with a direct gas rifle. 6) There’s nothing more fun about shooting a 9mm from your shoulder."
