JP Enhanced Gas Ring for .308 AR
The JP Enhanced Gas Ring is a one piece, drop-in replacement for the standard factory set of 3 gas rings. Compatible with DPMS Pattern .308 AR rifles. Unlike the standard set of three gas rings that have gaps that must be kept out of alignment with one another to avoid gas leaking, the JP one piece gas ring has no alignment issues to worry about. Additionally, it has less friction inside the bolt carrier for smoother operation, yet has a superior gas seal. This is a simple and inexpensive upgrade that belong on every .308 AR Direct Impingement Gun. Installation is simple and can be done in a few minutes - just wind it on like a key chain.
As a replacement for traditional three-piece gas rings, 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™.
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 operational window while the edge of the rings
utilizes the cycling action itself to scrape the walls of the carrier,
helping shed fouling with every shot.
*The JPEGR-308 is not compatible with large-frame Armalite bolt assemblies.
