Description
Ratings (3)

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 JPBC-2A Low Mass carriers that reduce felt recoil and increase bolt speeds slightly for enhanced rapid fire handling, or the standard JPBC-2A 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 carriers feature JP’s super-hard QPQ finish for maximum wear resistance and minimal friction. Extractor, firing pin, and all other components are included.

Excellent product (09/07/2015)

To begin with, I already own the black version that I run in my carbine. I purchased the stainless version initially simply because of the looks; it matched the stainless barrel I was using at the time in my 6.8 build. The stainless is mirror-finished and extremely smooth. It takes lubrication very well, to the point that a function check feels like the carrier is riding on ball bearings. I highly recommend this unit to anyone who wants a lightweight carrier to go with an adjustable gas block and low-mass buffer / silent captured spring.

Since it *is* stainless, I don't recommend it for any real-life SD/LE scenarios. Not that I think a small bit of stainless would be that much of a problem, but if you're operating at that level you're going to want every advantage you can get...which is why JP also sells the black version. For a hunting, benchrest, or run-and-gun competition rifle, its a worthy investment. Buy with confidence.

Super Smooth (09/10/2015)

I use this BCG on my first build. I basically have a JP gassed AR15, BCG, JP Silent Capture Buffer and JP Adj Gas Block. My First build is more for precision but I can quickly change it to competition when the time comes. Smooth operation of the BCG due to its light weight, and you barely feel anything shot to shot.

Perfect for a comp gun (30/04/2012)

These things are slick. This bolt carrier coupled with an adjustable gas block is perfect for dialing in a rifle. Very easy to clean and amazing fit and finish, JP knows what they are doing!!
