This bolt works amazingly - JP Enterprises High Pressure Enhanced Bolt Assembly

I have these on several MSR 10's. And any and all issues I've had are immediately rectified. No more extractor marks, no more ejector marks and the firing pin and bolt are high pressure rated. Do not misconstrue this to mean you can run overloaded ammo. I predominately run max loads after a ladder test if possible. And pertinent to cartridge and firearm MAY progress a bit over that, but not as a rule. I put this one in a 45 Raptor as it is recommended on may forums. And it was on sale.i have them in my 6.5 Creedmoor (BCA) and 308 (Also BCA) which both had bolt issues. These work and I highly recommend them!
