  • AR-15/ 308 AR ENHANCED GAS RINGS J P ENTERPRISES
    $9.99

    Item Code: #453217907

    Availability: In stock

    After testing numerous minute grind callouts, the final JP Enhanced Gas Rings spec is the perfect balance of a solid gas seal with a very low-friction relationship between rings and bolt carrier. Reducing the resistance between these components directly results in an overall increase in the rifle's reliability while the rings utilize the cycling action itself to scrape the walls of the carrier, helping shed fowling with every shot. The JPEGR-308 utilizes a one-piece design similar to the Mcfarland rings. Unlike the Mcfarland rings, though, our precision-ground gas rings are engineered to precisely suit DPMS-patterned carrier group components such as our own JP EnhancedBolt™.

  • AR-15/M16 DICTATOR ADJUSTABLE GAS BLOCKS PATRIOT ORDNANCE FACTORY
    $169.99

    Item Code: #453217907

    Availability: In stock

    This 9 position adjustable DI gas block provides the ultimate range of adjustability and versatility. The addition of a suppressor typically increases the level of back pressure within the rifle system. This increase will prematurely wear parts and increase the amount of gas/carbon introduced into the chamber. With the Dictator, you can now control that rate of fire, gas flow and ultimately the reliability of your system. The Dictator is a low profile gas block, fitting nicely under rail systems with a picatinny rail channel of ½” or greater. Adjusting the gas system is easy, the front of the gas block has a dial that accepts a flat screwdriver, 3/32” hex wrench and dictation tool included in the Dictator gas block kit. The Dictator features a straight gas tube, but why? The advantage of a straight gas tube is that it eliminates the heat buildup that exists at the bent portion of a standard gas tube. This feature is extremely important for select-fire and/or suppressed rifles which are subject to very high heat levels. By reducing the built up heat, you now have a more reliable, longer lasting gas system. Each Dictator gas block kit comes complete with the applicable length gas tube. The 2 lengths currently available are carbine and mid-length. This gas block is setup for barrels manufactured for a .750 gas block.
