This is what you want for accuracy. Little known, JP bolt is what standard headspacing for AR10 barrels are set off of. It does weight more, but it allows you to shoot heavier bullets at higher velocities

Quality is obvious

by APO, Verified Owner from CA, United States Written on November 8, 2025
Excellent buffer. Used to replace a young mfg carrier for my dpms ar10 that never seemed to be right. Much smoother operation and it just looks good contrasted against the black rifle.

JP LMOS BCG

by Quickcooper61, Verified Owner from CA, United States Written on October 30, 2025
As always JP's stuff is flawless in quality, design and function. Highly recommend the LMOS system. Speeds up cyclic rate by a noticeable amount and after turning the gas system it definitely softened the recoil a decent amount.

As advertised!

by S Rozar, Verified Owner from TN, United States Written on December 3, 2024
Very pleased. Very smooth no slop. I used this in my 22 Creedmoor build along with a custom barrel. Cycles great. I also reload. Brass looks great!

exceptional finish.

by tester1, Verified Owner from AL, United States Written on October 13, 2024
Was the recommend bolt for precision. I can see why. Don't recall anything this finely machined. With the one piece seal and seal run this smooth, it literally glides in and out of lockup. Haven't gauged anything other than headspace, but there is no discernable runout between the bolt and the carrier.
Pros:
  • seeming perfection
Cons:
  • obviously made with black magick
Would recommend: Yes

Works flawlessly

by PT, Verified Owner from CA, United States Written on May 23, 2022
I used this BCG for my 6.5 Creemoor build. Installation was a snap and work flawlessly. This is used in conjunction with the JP silent captured buffer spring. Recoil is very mild and smooth. Build quality and finish are excellent.
Pros:
  • Excellent finish
  • Excellent build quality
  • Easy Insallation
Cons:
  • None
Would recommend: Yes

JP Low Mass BCG

by Ray, Verified Owner from OH, United States Written on February 21, 2022
Great piece of kit. Super smooth and reliable. The coating is perfect and uniform, this has been 100% reliable for me. This really took my .308 to the next level. It cut down on recoil quite a bit. The adjustable buffer can be added but I didn't, this works perfectly fine without it.

The most buttery bolt there is

by Rich, Verified Owner from NC, United States Written on October 18, 2021
Yes, its very expensive, but without a doubt it is the smoothest bolt carrier I have ever felt. It runs great in my Aero M5 build. It cleans pretty easily if your into that kinda thing. JP really is a step above most. The quality control is amazing, they are quite helpful with questions and other help. Its a pricey bolt but I certainly don't feel I overpaid. The quality is all there.

Second lightest carrier i could find

by Aaron Green, Verified Owner from WA, United States Written on April 14, 2021
When building for light weight the only carrier I found that was lighter than this one is from V Seven however in todays stocking crisis I couldn't find one. I emailed JP Enterprises and ask about ship times they recommended coming to Optics Planet as they had orders in already being filled. The carrier shipped way faster than the expected ship date (2 months faster). The part numbers are a little confusing when trying to order the complete BCG with bolt and firing pin so pay attention. That being I said I reached out to support via chat and as always the representative was very knowledgeable and made sure I ordered exactly what I was looking for.
