Colt Automatic Rifle Ares Shrike 5. The lineup of SIG rifles fulfills many different roles including personal defense weapon, close quarter battle, tactical, and patrol. When you want to remove the gas valve, you simply depress a small button and turn the gas valve counterclockwise, and the piston and valve come out for easy cleaning. This operating system reduces carbon fouling, excessive heat and unburned powder in the action, ensuring further improved reliability and function. The hammer is then captured by the disconnect and held in place. My Gen 1 model shot just great, as does this Gen 2.

My Gen 1 model shot just great, as does this Gen 2. I loaded up four round magazines with the Winchester ammo and fired them as fast as I could. Saudr cam pin passes into the bolt, which allows for locking and unlocking and is retained in the bolt by the firing pin. I want more stuff like this! Having to operate the rifle in this position indicates the rifle needs maintenance.

It incorporates locking lugs that lock the bolt into the barrel extension. Taking the pushrod and piston out for routine cleaning is quick and simple. A quick field wipe-down after firing rounds showed almost no fouling in the bolt group or barrel.

You can attach it as either a two-point or a single-point sling, and the hardware comes already on the sling. The gas travels through the port in the adjustable gas valve and drives the pushrod rearward. The lower assembly contains the fire control mechanism selectorbolt catch, magazine well, magazine release, pistol grip, sling attachment points, and butt stock assembly.


When I did receive it, I noted that the quad-rail handguard was the same as that found on the Gen 1 model, as was the MagPul MOE 6-position telescoping butt stock. I did change it to position 2 and 51 that my empty brass was sailing farther away from the gun—more gas was skg released into the pushrod system.

The has a four position gas regulator, allowing the user to choose the amount of gas ssig to the piston. xauer

Review: Sig Sauer Model Gen 2 Piston-Driven AR –

Some piston-driven ARs suffer from excessive wear in 561 buffer tube from the bolt carrier tilting. A quick rundown on the Sig Gen 2 model is in order: Keeping Its Cool Compared to direct gas impingement ARs, the stayed very clean and cool during testing.

I immediately broke the gun sif and took out the bolt carrier group, and it was cool to the touch and pretty clean. I never had any functioning problems, and all brass was thrown into a nice little pile. The rifle is hammer-fired and has a two-stage trigger mechanism in the SIG Marksman, while all others have a military specification single-stage trigger. For my accuracy testing, I did my shooting at yards with a cheap Bushnell 3x-9x 40mm scope.

This gun looks pretty much like most higher-end ARs, albeit with a piston-driven operating system. Position 3 Suppressed is for firing with a sound suppressor and is a partial cutoff of the gas system, still allowing for the cycling of the weapon.

The adjustable gas valve adjusts the amount of gas flowing into the action of the gun. In this position, a larger volume of gas is released against the push rod.

The nice thing with an adjustable gas piston system is that if you have weak siig or ammo that is too hot, or if the gun gets dirty, you can simply adjust the gas system so the gun will run better under those conditions. With three attachment points, you can put the sling where it works best for you.

I was getting consistent 3-inch groups with these two loads. This innovative operating system reduces chamber debris gas residue and carbonand allows the rifle to run cleaner and cooler.

A quick glance at the is in order. Short-stroke pistonrotating bolt. Basically, the SIG has four setting options the 7. The upper receiver is a flat top, and it has a quad-rail forearm for mounting accessories.

It is quicker to change from one gas position to another simply by turning the gas valve by hand.
