PISTON SYSTEM INFORMATION

Adams Arms is committed to building the highest quality parts and accessories available for the AR15/M16 platform rifle.

All of our parts are built with high quality domestic 440 stainless steels built in the U.S. by U.S. workers.

We stand by our quality with a lifetime guarantee.

Q. What is required to maintain and clean the Adams Arms Piston System?
A. The Adams Arms Retro-Fit Piston System keeps the hot burning gases from entering the receiver. This means the normal time and energy exerted on cleaning your AR15/M16 will be drastically reduced. To clean our system, simply wipe off the parts with a dry, clean towel.

The areas of the system that see the most dirt is the front of the gas block and the back of the plug and drive rod sleeve. These parts may require some scrubbing with a nylon cleaning brush or old toothbrush and some cleaning solvent.

To access the drive rod for cleaning, simply press the detent button and turn the gas plug knob to the 9 o’clock position. Then remove the drive rod and gas plug. Wipe the outside off with a dry, clean towel and spot clean with your choice of solvent and a nylon brush as needed.

If you find an area that has a heavy build up of carbon which will not come off with solvent, use a knife, pick, or some type of scraping tool to remove the heavy spots. Due to our meloniting process the parts are virtually scratch proof and shouldn’t show any wear.

Once cleaned, replace system and continue shooting. Oiling the piston system is not necessary; however, if you choose to do so, apply only a thin coat over the moving parts.
