JP | Ultra LMOS™ Bolt carrier
Small-Frame
7075 T6 Aluminum
Anodized
Includes titanium firing pin and JP Enhanced Gas Ring. Weight: 3.76 oz. with key installed
While JP introduced the original aluminum bolt carrier over a decade ago, JP finally discontinued it after several customers had difficulties with its rather strict maintenance needs and changed over to the stainless steel design. As it turns out, JP left a gaping hole in the market with some devoted customers hoarding the old parts or buying them up at steep prices. To meet all that pent-up demand, JP has gladly reintroduced a new-and-improved and easier to run ultra low mass carrier manufactured from aircraft-grade 7075-T6, the reborn JPBC-1.
Reengineered with lower maintenance requirements, the new JPBC-1 is the ultimate in improved reliability and performance, especially when combined with a high-efficiency JP muzzle brake, adjustable gas system and Silent Captured Spring. The end result is a carrier that leaves your .223 shooting like a rimfire .22.
The JPBC-1 checks in at 2.9 ounces less than our 416 LMOS™ carrier and 0.7 ounces less than even titanium carriers offered on the market today. Each unit comes as a complete kit including JP precision-ground, one-piece gas ring as well as a titanium firing pin. Run in concert, this gas ring ensures perfect bore-to-gas seal fitment in the JPBC-1 and minimized friction to enhance reliability when fouled while the titanium firing pin eliminates any possibility of slamfire at the higher bolt velocities.

Compatibility and Usage
Non-ferrous specialty carriers should be considered consumable rather than lifetime parts. The JPBC-1 yields a performance advantage for competition applications at a price. Your usage and maintenance will determine the duty life of your carrier.
The JPBC-1 is a competition/race gun part only and is not recommended for any duty/defense use where absolute reliability is required.
This carrier should also be run with an adjustable gas system to minimize stress on the entire bolt carrier assembly.
This carrier is not recommended for use with gas systems shorter than mid-length for longest service life. Use with carbine or shorter gas systems may result in gas erosion in the tail stock area and subsequent leakage and reduced service life.
To help avoid the instance of slamfires, this bolt carrier comes packaged with a titanium firing pin. We strong encourage use of a titanium firing pin with this carrier to ensure safety.
Not for use in .308 AR-type rifles.
