Adams Arms "P" Series- 300BLK LIFECOAT Left Handed Coated Carrier Piston Kit
These are in stock but are now shipping with Black Lifecoated Left Hand Carriers. The Gold were a small test batch that sold out and will not return. The Lifecoat is a PVD Nitride finish and is superb for lubricity, hardness and corrosion resistance.
ADAMS ARMS PROPRIETARY "LIFECOAT" FALLS UNDER THE CATEGORY OF MELONITE NITRIDE FINISH BUT IS A MORE ADVANCED MULTI-STEP PROCESS USING PVD INSTEAD OF LIQUID NITRIDE.
This finishing process provides a surface hardening condition that protects against corrosion and wear better than hard chrome or nickel plating. While liquid nitriding is a surface modification technology, Physical Vapor Deposition (PVD) coating involves the deposition of thin (2-10 microns; 0.0001”–0.0004”) proprietary films (i.e. TiN, CrN, Ti(C,N)) on the surface of components. VooDoo Innovations (VDI) has trademarked the term LifeCoat. The term is used to describe a multitude of coating processes that best fit the application of the specific AR15 part. Since each part serves a different purpose, it has different applicable needs for surface protection, lubricity, hardness and color. Some coatings are “Line of Sight” coatings and can only coat outside dimensions of a part. While other coatings are baths and therefore have the ability to coat blind holes as well as other internal cavities. All coating processes have an intended purpose. Some coating processes offer superior lubricity, but may not be hard enough to hold up over long periods of time on point-to-point contact surfaces. VDI has taken their years of experience in the world of Mechanics, Engineering and Firearms’ Technology to apply these processes to their best intended application. Having the ability to offer specific materials, machining techniques, coatings and apply them to the purpose of the part is what allows them to offer Life-Time Warranties on the parts produced. Many variables come into play when applying various coatings; from heat and surface preparation to friction on mating contact points.
This system will work with .223/5.56 x 45 mm NATO.
- Patented One-Piece Bolt Carrier
- P Series Micro Block - Adjustable (5 Settings - 100%/74%/53%/32%/11%)
- Bolt Spring
- Drive Rod with Bushing and Spring
- Installation Instruction Card
The Adams Arms Piston System:
- 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.
- Has a Lifetime Warranty.
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.
Micro Gas Blocks should have the set screws torqued to 87 in-lbs
