Product Description


  • Includes all components for a complete Bolt Carrier Group
  • JPBC-2 Full mass bolt carrier
  • JPEB-223 Enhanced Bolt (will work for 5.56)
  • Cam pin, firing pin and firing pin retention pin

This is considered the best bolt carrier group available on the market today. Strong-Side Tactical is an authorized Master Dealer with JP Enterprises.

Compatible with any standard Mil-Spec upper! This bolt carrier group is for any application where absolute reliability is the main criteria, the FMOS™ or Full Mass Operating System with 416 stainless steel special design carrier that includes forward assist serrations and a dust cover notch. The bore of the JP stainless carriers 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. When properly lubricated, both systems make your rifle feel like it was cycling on ball bearings.

The JPBC-2 bolt carriers provide a100% increase in bearing surface for smoother operation and improved alignment and lower wear in the upper receiver. Both are AR-15 semi auto configuration in the rear with the mil-spec longer cocking pad in the front for best reliability. This is hands-down the best designed and highest quality general purpose carrier on the market. Sold as carrier with installed key.

The latest edition JP EnhancedBolt™ is made from SAE 9310 high-grade steel. This material makes for an extremely hard surface with a tough, ductile core resistant to structural failure and a life expectancy far exceeding Mil-spec 8620-type bolts. SAE 9310 is the same type of steel used in the transmission gears of Formula One racecars, and the high-load application of a bolt assembly is ideal for this state-of-the-art material; the results of actual full-auto endurance torture tests prove it.

    Thes are by far the best BCG's I have used.
    I have them in 4 out of my 5 ARs. These are top quality in every aspect, from design and materials used to fit and finish. I you like to use all the best available parts in your AR, this is the unit for you. And Strongside Tactical ships lightning fast with the best prices I've found.

  3. Only the best 5 Star Review

    Posted by on 11th Apr 2014

    I bought this BCG for a custom build I did as a service/duty rifle. The finish is amazing and when coupled with the remainder of my build, I have experienced zero malfunctions. The BCG is grouped with a Larue Tactical buffer spring, Spikes Tactical T2 heavy buffer, Noveske Afghan 14.5" barrel and a Surefire SOCOM muzzle break. I have zero muzzle rise, decreased audible action noise, and complete confidence in my weapons system.

    Buy this BCG if quality and performance are your goals. BEWARE!!!!!! If you buy this BCG, you may not ever buy any other brand....this thing is incredible.

    I tend to be hesitant when it comes to ordering parts offline from websites I have never heard of but strong side tactical definitely delivered the best service possible! When it comes to the JP bolt carrier group, you get what you pay for! The quality of this bcg is something you have to see to believe. I will be running one in every gun I build here on out.

    Posted by on 23rd May 2013

    Lew not only was able to provide me with the best BCG but most of all the customer service is the best anyone could hope for. Presently, it is very difficult to find parts as everyone knows but Lew was able to provide me with basically all the upper components for my build in an unbelievable timeframe. Thanks Lew and Strongside is the best.
