JP Low Mass Complete Bolt Carrier Group for AR-15/M-4 Rifles and Carbines

This is the ultimate Complete Bolt Carrier Group for your AR-15. It includes the JP Low Mass Carrier, JP Enhanced Bolt with Carrier Completion Group parts (Firing Pin, Cam Pin, Firing Pin Retaining Pin). Very Slick, Black QPQ Finish on Carrier and Bolt made of 9310 steel with Chromium Nitride finish. The best in the industry.

The JP Low Mass Carrier is 2.3 ounces lighter than the JP Full Mass Carrier to reduce the movement of the gun during cycling and speed up recovery time. Works best with standard weight or Low Mass buffers and an adjustable gas block for full effect. An adjustable gas block is an important component of a Low Mass Operating System to allow the shooter to tune down the gas for reliable function at the optimal speed. The bore of the JP stainless carrier has a roller burnished finish for frictionless operation with no chance of peeling chrome as in standard mil-spec carriers. The exterior bearing surfaces are hand polished using a Quench-Polish-Quench (QPQ) process to yield incredibly hard and lubricious bearing surfaces. Finish is black. When properly lubricated, this system is designed to make your rifle feel like it is cycling on ball bearings. This carrier features a 100% increase in bearing surface for smoother operation and improved alignment and lower wear in the upper receiver. No forward assist serrations, but does have the dust cover notch. The JP

Enhanced Bolt is made to the highest standards in the industry for materials and workmanship for high accuracy and the longest service life possible. Bolt is made of 9310 steel which has 10 times the life expectancy of the typical 158 carpenter steel. Has been engineered to add material in critical areas to further increase strength. Includes JP enhanced gas ring which is a smoother, one piece gas ring for a better gas seal with lower friction. This will feel super smooth and easy to move the bolt right out of the box while improving the gas seal, unlike many with tight, high friction gas rings which must be kept unaligned. Bolt finish is Chromium Nitride for durability and lubricity. This is hands down the best designed and highest quality bolt carrier group on the market.
