Centurion Arms’ battle-built and proven special purpose 5.56mm tack driver—a designated marksman’s dream machine!
Long-range peacekeeper! The sniper depicted here is fielding the exact rifle, uniform and support gear used by U.S. Navy SEAL’s on frontline duty in Iraq.
In today’s battlefield and on the streets of urban America, the role and type of traditional sniper rifles has changed drastically over the last several years. Whereas bolt-action 7.62×51 sniper systems dominated before, in today’s fast-paced engagements with a different type of enemy, the platform of the sniper rifle has taken two paths. Long-range precision sniper rifles have become large, specialized systems that are chambered in cartridges like .338 Lapua Magnum, or .50 BMG. To fill the role of providing highly accurate fire in shorter-range combat environments, the precision 5.56mm AR-15/M16 based system is becoming a dominant force in the hands of designated marksmen, an indigenous member of the small infantry unit. Considerations of collateral damage as well have shown a greater need for pinpoint accuracy, with a less-powerful round, at closer engagement ranges.
The 5.56mm precision rifle used by special operations snipers in both Iraq and Afghanistan is the MK 12 Mod 1 Special Purpose Rifle. It is a culmination of many years of development, and has proven a success in the field. The program itself grew out of developments at the Naval Special Warfare Center, Crane Division, for use by Navy SEALs. These guns are also in use by U.S. Army Special Operations soldiers. Limited numbers are reportedly in use within the USMC.
Centurion Arms’ MK 12K variant is geared towards law enforcement use. Its versatility allows for it to be re-configured from a sniper system to being suitable for entry work with an optics change to an Aimpoint Micro T1 optic from its normal magnified precision rifle optic.
The MK 12 system has several variations, but the heart of the system is that of an M16 with a free-floating 18-inch match barrel that utilizes the OPS Inc. suppressor and matching muzzle brake and alignment collar. They have been built at Crane with either fixed A1 or A2 stocks, and some have been field modified by being put on collapsible-stock lower receivers with SOPMOD stocks. They have utilized various mid-range variable scopes from Leupold, and the current NightForce 2.5-10X optic. The current rifles use a Knight’s Armament fore-end with backup sights and trigger. They are also fitted with Harris bipods. The Knights rail system allows for numerous laser, white light and night vision devices to be utilized.
The NightForce 2.5-10X scope is a near perfect optic for the MK 12 and how it is used in typical Sandbox deployments.

First things first! Check out this awesome looking trio of AR-15′s. A MEGA Arms AR-15 Pistol!?!?!? How cool is that? The AR-15 in the middle features MEGA’s new NiB Coated Monolithic Upper and NiB Coated Ambi Lower. The one on the bottom has MEGA’s Tubular Monolithic Upper. Pretty soon there will be another great option for a high end AR-15 as MEGA Arms will be selling these complete rifles starting in the second quarter of 2012.
The AWESOMENESS level of this next picture is off the charts! Check out the XS Products drum attached to the MEGA Arms MATEN .308 rifle below, the new 50 Round .308 Drum from XS Products. It’s machined to match the design of the MATEN Upper Receiver. That is one awesome looking rifle!
MEGA Arms will start producing a tubular version of their Monolithic Upper receiver this year and will offer it in NiB coating as well.

Special weapons that collapse, slide or fold to jump small—then fight big!

When Russia and Germany created the earliest parachute troops, one of the problems faced was getting the paratroopers to the ground along with their weapons. Jumping with weapons created an array of difficulties. Most military rifles of the time were long and were likely to catch on the parachute lines or otherwise impede the jumper. Weapons also offered the possibility of injuring the jumper should the barrel or stock impact vital organs during a hard landing.
Because of these and other considerations, early German paratroops jumped with just a pistol and grenades while their rifles and SMGs were dropped in a separate case. This became a problem, however, when they encountered resistance upon landing because they had to fight their way to the drop case and extract their weapons. Later, jumping with an MP38 or MP40 SMG gave the paratrooper more range and firepower but still not as much as a rifle. The MP43/44, generally considered the first effective assault rifle, gave the German Fallschirmjager a more effective weapon, but it came too late in the war to use on major jumps.
This HK93A3 collapsible-stock rifle has a Zeiss 1.5-6X scope on a quick-detach HK clamp mount.
Other World War II airborne troops tried other solutions. Japanese paratroopers had the Type 2 Paratroop rifle that could be broken into two sections. U.S. paratroops experimented with jumping with just a handgun and fighting knife and retrieving their rifles from drop containers in the German manner. However, later they jumped with Thompson SMGs or Garand rifles. A special jump case would include a disassembled Garand. After mid-1942, a special M1A1 carbine with side-folding stock was available, although some airborne troops continued to jump with the Garand for more range, or the Thompson for more firepower. Once the Sten gun was introduced, it became the primary jump weapon for British airborne troops.
Korea’s Daewoo K1A1 has been used by ROK special ops units who appreciate the compactness with stock collapsed. Shown is the 19-inch barreled civilian K1.
