Eliminated 6.5 CM primer punctures by using this bolt.

So I had a faxon complete BCG, was using it with a faxon match barrel chambered in 6.5creedmor. Had an issue with punching primers, so after some research decided I needed a high pressure bolt. Once installed my BCG failed the stand test, but I took it out regardless and found it short stroking. I changed out the gas rings on the bolt and it cycled flawlessly. If considering this bolt, I highly recommend sourcing new gas rings as the ones included do not seal properly to cycle.

This bolt uses a smaller firing pin hole than what's usually used in 308 style bolts in semi-autos. I no longer see any primer cratering on my cartridges. The finish and machining on this bolt is also top notch.

I replaced my Aero bolt with this JP's and what an improvement. My previous loads, shoot nicer my primers aren't deformer after shooting any longer, much better performance, my groups have also improved. Thanks JP's

Built a new creedmoor ar10 with Criterion barrel and they suggested to use JP . Pricey I thought but was worth every penny . It’s shines working and I would tell anyone that they should not be worried of the higher prices . Buy once – cry once

Dropped right in to my PSA M110-A1 bcg. Will be my main bolt and will keep the PSA one for backup. No additional gas tweaking or weight adjustments. Added the Pof roller cam pin and this thing is like butter.
