Standard Armament can adapt a latch to fit any gun application or platform. We do however offer standand latches to fit most applications. They are:
Standard Coating: Standard Armament’s standard coating is a Solid Film Lubricant per SAE AS5272, MIL-L-46010 and MIL-PRF-46010. The lubricant is applied to components and baked at Standard Armament’s facility. The resulting surface has good friction and wear characteristics.
Optional Coating Electroless nickel-Teflon: Electroless nickel PTFE coating combines the self lubrication properties of PTFE with the high wear resistant hardness of Electroless nickel. The key properties of Electroless nickel-PTFE are:
Cerakote: Cerakote is a coating that is often used on firearms. This coating provides a high performance surface and is available in a variety of colors.
Optional pre-coating process of Passivation: Prior to having the coating applied the completed components are chemically processed (Passivation per AMS QQ-P-35) to remove contamination near the surface of the component. The contamination near the surface is often a starting point for oxidation. After Passivation is completed, the components have their finish coating applied.
When the ammunition box is located below the height of the weapon, the ammunition will often download when the receiver is opened. To prevent this Standard Armament has developed a ratcheting device (Pawl Assembly) that allows the ammunition to only flow toward the weapon. The gunner can override the Pawl with one finger to download ammunition. Shown is a Pawl for a 7.62mm chute, Pawl Assemblies are available for all calibers of feed chutes.
Standard Armaments small caliber chutes, 5.56mm, 7.62mm and certain .50 Cal/12.7mm, have optional Pin and Plate reinforced links available. The reinforced link is used in applications where additional stress is being applied to the chute. One application is when the ammunition path uses a booster motor. During the start/stop function, timing differences may cause the ammunition to be pushed into the chute faster than the weapon is pulling the ammunition out of the chute. The buildup of ammunition in the chute will cause an increased in internal pressures. The Pin and Plate reinforced link provides a heavier duty connector to withstand the increased pressures. The Pin and Plate reinforced links have less flexibility than the standard link, but can be used to increase stiffness of the chute as desired.
Standard Armament has provided composite feed chutes for over 30 years. Some chutes have used hard composites to replace cast or machined parts others use more flexible composites to replace flexible components. As with our other products our Plastic/Composite Chute designs are driven be specific customer needs. Recently we have designed chutes in different calibers to use composite frames for an alternative design option.
