There’s a problem with Direct Impingement. Its dirty. It builds up carbon and fouls your internals. But what if we told you that there was a way to avoid this in your next build or even upgrade a current one! Adams Arms has been making quality piston kits for years and now we are bringing them to you! We are even throwing in a free barrel!
The system is self cleaning and sends gasses and carbon away from the operator
.625 Micro Piston Kit with FREE 14.5″ Barrel
Adams revolutionary Retro-Fit Piston System is designed to convert your standard direct impingement rifle to a clean, cool, reliable system without extensive modifications. Their patented piston system is a drop-in system that works on any mil-spec AR-15 and is compatible with most standard AR-15 parts. Adams kits have been treated by various coating applications to increase Durability, Lubricity, and Longevity, and come with a Lifetime Warranty.
The Adams Arms Retro-Fit Piston Drive System uses the same gas port on the barrel to work the action the inverted piston. Instead of directing the gases into the receiver, they go into a gas plug and drive rod sleeve invented by Adams Arms. The gases are contained inside the drive rod sleeve and push the bolt carrier rearward using the gas pressure to cycle the action.
Adams Arms proprietary operating systems mechanically actuate the bolt carrier external of the receiver. This keeps the internal receiver and all the critical moving parts clean and free from heat and carbon build up.
Here are some of the main differences when using the Adams Arms Operating System:
This system will work with .223/5.56 x 45 mm NATO.
Kit includes:
- Patented One-Piece Bolt Carrier
- .625″ Micro Gas Block (Non-Adjustable)
- Bolt Spring
- Drive Rod with Bushing and Spring
- Installation Instruction Card
- 14.5″ Ultra Lite VooDoo Barrel
- A short stroke free floating piston system.
- Is Self-Cleaning.
- Carbon and gases are expelled forward, away from operator.
- Corrosive resistant coating processes.
- Harmonics are not transferred into the barrel.
- Doesn’t vent directly to atmospheric pressure; this eliminates flash signature and super sonic crack which is optimal for night vision and suppresses fire.
To select the correct length kit, use the following measurements:
- Carbine: 7.866″ from barrel extension to shoulder
- Mid: 9.866″ from barrel extension to shoulder
We recommend using a standard barrel nut or barrel nut with similar measurements for proper fit and function of the kit. Many aftermarket proprietary barrel nuts do not offer the clearance for the drive rod or proper seating of the spring and bushing.
