I shoot a lot of 3 gun and I see many competitors use JP. Some swear its the only thing that holds up in the MGM Iron Man where you are shooting 1,000+ rounds for the day. Not true, not everyone has JP as their bolts and are doing just fine.

I saw this on brownells. Looks pretty similar -$100 in cost over the JP.
Im not convinced that you dont need to oil/lubricate plus you just wipe off carbon.
