High-Performance, B/C Groups In Choice Of Full- Or Low-Mass Configuration

Precision-machined, stainless bolt-and-carrier group features JP’s enhanced bolt made of high-grade 9310 steel for a significantly longer life expectancy than standard mil-spec bolts. Set is available with choice of a JPBC-3A, JPBC-3SPA, JPBC-2A-6.5G, and JPBC-3A-6.5G Low Mass carriers that reduce felt recoil and increase bolt speeds slightly for enhanced rapid fire handling, or the standard JPBC-2A and JPBC-2A-6.5G Full Mass carriers that replicates the normal carrier weight and is preferred for duty rifles or any time absolute reliability is required. Standard weight carrier features a 100% increase in bearing surface for smoother cycling and reduced wear on the inside of the receiver. Both the JPBC-2A, JPBC-3A, JPBC-2A-6.5G, and JPBC-3A-6.5G carriers feature JP’s super-hard QPQ finish for maximum wear resistance and minimal friction, while the JPBC-3SPA and JPBC-3SPA-6.5G comes in a polished stainless finish. Extractor, firing pin, and all other components are included.

Best AR Bolt I Have Used (16/12/2013)

I have used high quality Mil-Spec bolts and various NP3 bolts for AR builds and this one is by far the best. The fit and finish is amazing and the carrier cleans up very quickly. This bolt functions perfectly and does seem to smooth up the operation of the rifle. It is expensize but well worth it. Will be exclusively using this bolt for future builds.

BEST BOLT CARRIER GROUP OUT THERE (27/04/2016)

I used JP's bolt carrier group in 3 upper builds over the past year. It is expensive but worth every penny. It headspaced perfectly with 3 top barrels. It glides through the upper receiver with practically no resistance. The machining and finish are at a level not seen in any BCG out there. All surfaces are polished to a mirror finish. Performance cannot be matched. I am picky as can be when spending my hard earned dollars on expensive parts. Spend the money. You will not be disappointed. I am about to buy JP BCG number 4.

This IS the carrier you are looking for. (02/10/2016)

I currently run 2 different JP bolt carriers in my 4 AR's (building my 5th now which will have the full mass), and all get the JP enhanced bolt.

Why do I love them? For starters JP Enterprises has been around a long time and had set the standard for quality BCG's and other products. The quality is immediately apparent when you open the package and look at it. The high polish stainless looks like a mirror, you can see the effort that goes into each one. One of mine is coated in TiN, one Microslick, with TiN bolts on both (I also run an entirely Microslick setup on one). I tried a RCA titanium bolt carrier for the immense weight savings and it is really picky and constantly gives me problems. Unless you are building a race gun shooting mouse fart loads just go Full Mass and make your life easier. Pair that with the JP/Syrac Adjusable gas block (only one on the market that is click-adjustable WITH a detent to lock your setting in place) and you will be grinning every time you shoot your AR. I know I am.

THANKS BROWNWLLS AND JP ENTERPRISES!

Top of the Line (25/07/2017)

Excellent product I have been running it in my Colt LE6940 the last several years. No issues and as far as I am concerned it is the perfect.

Nice. (11/08/2018)

Recommend using with Geissele buffer/buffer spring and ALG advanced combat trigger for a smooth, durable, and RELIABLE set-up.
