reduces reciprocating Mass To soften recoil
Lightweight, stainless steel bolt carrier has significantly lower reciprocating mass than a standard carrier for softer recoil impulse on competition rifles. Helps limit felt recoil to get you back on target for fast follow-up shots. Lightening cuts reduce weight without sacrificing strength, and the forward assist serrations have been omitted for competition use. Extra-wide carrier rails have extra bearing surface to improve bolt alignment and reduce wear. Comes with carrier key installed and staked, and features a dust cover notch. JpBc-3 is available with bright polished finish or black QPQ finish, a five-step process that produces an exceptionally hard, wear-resistant surface with natural lubricity. JpBc-4sp comes in bright polished. For best performance and to minimize impact wear, use JPBC-3 styles only in rifles with JP LowMass Recoil Buffer, Speed Hammer, and Reduced-Power Spring Kit, all available separately. a b SPECS: 416 stainless steel. JPBC-3 – Black QPQ or bright polished (SP) finish. Fits AR-15. JPBC-4SP – Bright polished finish. Fits JP LRP-07 and DPMS LR-308 platforms and requires JP or DPMS subcomponents only, including firing pin, cam pin, firing pin retainer, bolt assembly. Both styles are recommended for competition rifles only. #452-000-039EN JpBc-3 Black Low-Mass Bolt carrier, 2E194C29 � � � � � � � � � � � � � � � � � � � � � � � � $ 214.99 #452-000-156EN JpBc-3sp Low-Mass Bolt carrier, 2E194J29� � � � � � � � � � � � � � � � � � � � � � � � � 214.99 #452-000-157EN JpBc-4sp Low-Mass .308 Bolt carrier, 2E231L43 � � � � � � � � � � � � � � � � � 256.99

JP ENTERPRISES AR-15/M16/AR-STYLE .308 ENHANCEDBOLT™ BOLT ASSEMBLY
Designed For extra-Long service Life
Complete bolt assembly is precision machined from an ultra-strong steel alloy to last up to 10 times longer than a standard carbon steel bolt, minimizing the risk of bolt failure during a critical engagement. SAE 9310 steel has a tough, ductile inner core highly resistant to stress fracturing, with a hard outer surface that resists galling and wear, to ensure a service life of up to 60,000 rounds. This is the same steel used in the transmission gears of Formula 1 race cars, so it’s ideal for high-impact, high-heat applications like sustained full-auto fire. Meticulously machined radiuses on all 90-degree corners on the locking lugs help distribute impact force evenly and further reduce risk of premature wear and cracking. Fully supported extractor face and precise extractor engagement further ensure smooth, reliable cycling. JpBc Bolt completion Group adds to the EnhandeBolt a firing pin, cam pin, and firing pin retaining pin. High pressure (Hp) .308 JpBc has a reduced-diameter firing pin hole and a matched .062" low-mass firing pin to help eliminate primer flow and risk of pierced primers, allowing a broader choice of SAAMI/NATO spec ammunition. Does not allow use of “overloaded” ammunition that produces pressure exceeding SAAMI specifications. a b SPECS: SAE 9310 nickel-chromium-molybdenum steel, hard NickelBoron (.223 & 6.5 models) or black Magnesium Phosphate (.308 models) finish. Fully assembled with extractor, gas rings, ejector, pins, and springs installed. .223 fits AR-15/M16 and clones. Fully compatible with any milspec bolt carrier. 6.5 Grendel fits rifles with a mil-spec bolt carrier and 6.5 Grendel sub-components. .308 fits JP LRP-07 and DPMS LR-308 rifles only. 9mm fits 9mm-chambered rifles with standard .223 hammer; do not use a dedicated 9mm hammer. #452-000-111EN .223 enhancedBolt, 2E107D14 � � � � � $ 118.99 452-000-163EN .223/5.56 Bolt completion Group, 2E124L29� � � � � � � � � � � � � � � � � � � � � � � � � 137.99 Outstanding performance; Models For A variety Of chamberings

upgraded Design For increased Durability & Dependability
Updated design of the standard AR-15 bolt features a fully supported breech face and a dual-spring extractor system for extra strength and reliability to handle the 6.8 Remington SPC cartridge. Machined from an extremely hard steel alloy normally used in high-stress/heat applications like race car transmissions, then shot-peened and x-rayed for flaws before plating with a nickelboron (NiB) coating. NiB coating significantly reduces friction coefficient, so the bolt is less likely to be hung up by fouling, and wearresistance is greatly enhanced. Super-slick surface makes cleanup easy because carbon and gunk have a hard time sticking to it. a b SPECS: Ultra-hard steel alloy, nickel-boron plated, silver finish.
