OUT OF STOCK
Due to a family emergency we have had some delays in our production process.
With the same function as our standard M1A adjustable gas plug this version is a shorter length made for use with a suppressor. By adjusting the volume of gas in the cylinder it changes the speed of the op-rod and controls the harmonic vibration of the barrel. Our Adjustable gas system allows the operator to fine-tune the amount of pressure in your SOCOM M1As Gas system. Made to fit most suppressed rifles.
INSTRUCTIONS:
READ THIS FIRST: Unload firearm before making any adjustments! You will notice that the setscrew in the Gas Plug may be very tight and will not easily turn by hand. Once installed in the rifle it will become much easier. The setscrew comes at a factory set position, air will easily blow through it. The rifle WILL NOT FUNCTION at this position. Use it as a starting point, then screw in as necessary until rifle begins to function.
Installation: Remove existing gas plug, and replace with your new adjustable gas plug. Start with setscrew at the factory preset position. Turning the screw about ¼ turn at a time, tighten screw, and fire until the rifle functions reliably with your particular load. If the adjusting screws seems to loosen , install the hollow locking setscrew and tighten against the original screw locking it in place. Locating your Rifle’s sweet spot requires some trial and error. Once rifle is functioning properly, try turning the setscrew 1/8 of a turn at a time and fire a few rounds. Repeat until best group is found. Some shooters like to scribe a small line on the setscrew itself, and use it as a marker for identifying plug position (i.e. 3 o clock).
*Since handloading operations are beyond our control, we disclaim all liability for any damages which may result.

Quick delivery. Functioned as described on my SOCOM2 and reduced backblast to my face with suppressor attached. Note that the allen wrench didn't seem to fit, but it really does. You just get a 'feel' that it is slipping as you turn the adjustment, but after closer, well lit inspection, it was turning like is should. Highly recommend if you suppress an M1A series rifle.

SOCOM II with suppressor...well, if you want the suppressor to fit, you need this gas plug. Not to mention that it's adjustable! MUST HAVE. I've got these on my other M1A's and my M1 Garand. Any rifle that uses an op-rod.

I had to change out the gas plug on my Socom 16 because of the suppressor I added.

The Gas Plug was easy to install. I would recommend you have the Gas Cylinder wrench. Required about 10 rounds to dial in the setting.

Replaces stock Gas Plug with no issues. The Schuster Adjustable Gas Plug for the M1A Socom allows for adjustment of the gas driving the operating rod and bolt rearward. Works great to help with blow-back when using a suppressor and reduces wear and tear on operating rod system.
I Highly recommend using this product.

Installed and followed directions supplied with the gas plug. Worked perfectly! Very impressed and I am glad I purchased this product. Great job!

This is the only gas cylinder plug that is truly short enough to allow use of a suppressor on a Fulton Armory threaded gas cylinder lock. Other "short plugs" are still too long and protrude beyond the lock threads. Fit is perfect. I hope to get out and shoot this weekend. Customer support was GREAT. Answered my email question immediatelly.

Only problem was the provided Allen wrench was slightly to small for the adjustable plug. It fit the set screw perfectly, but would wiggle and slip without turning the plug. After a few shots everything warmed up and got loose enough that the plug would turn. Once the adjuster started moving the process of dialing it in was simple and fun.
