JP LMOS Carrier:
A low mass carrier provides the most significant improvement to felt recoil after the addition of a compensator. Our LMOS™ carriers remove much of the reciprocating mass out of the rifle's cycling. This translates into less felt recoil and less movement of the rifle. That means dramatically faster sight recovery and follow-up shots.
This carrier group includes our proprietary bolt design, the JP EnhancedBolt™. Superior in every way to a standard Mil-spec bolt, it's manufactured from SAE 9310, providing drastically extended lifespan with design improvements that ensure superior function.
The EnhancedBolt™ is compatible with any AR-15 platform using a Mil-spec bolt carrier and sub-components.
Package includes carrier, bolt assembly, cam pin, firing pin, firing pin retainer pin and instruction sheet.
Not for use in .308 AR-type rifles.
Features (bolt carrier):
Weight: 8.8 oz.
JP Silent Captured Spring:
|GEN 2 Silent Captured Spring (patented) for AR-15-type rifles
Includes spacer to allow for installation in both carbine- and rifle-length buffer tubes.
The JPSCS2-15 will not function with older Primary Weapon Systems (PWS) bolt carriers. The design of the carrier will prevent the rifle from cycling.
Competition Series Compensator
Let's face it, comps are easy to make. Perfecting them is the hard part.
Our original Recoil Eliminator will always be the benchmark for compensator performance. Every new comp design we develop strives to measure up while keeping a slimmer profile.
Tweaked over multiple iterations, our Competition Compensator lineup comes within striking distance. With ports tuned to match the RE Series as close as possible, these comps shoot flat and hold neutral. For the hungry competitor, that means getting back on target cracking followup shots as fast as possible.
This compensator meets and maximizes the potential allowed by the 1" x 3" dimensional rule, making it SOF/Tactical/USPSA Limited legal and optimal.
Package includes compensator, crush washer and instruction sheet.
