I will quickly run thru what I thought about it . Staking is good, maybe a bit overkill as it split the steel upon staking again no big deal to me but i know a few people that would throw a fit . finish is as adequate as any bcg. Firing pin standard all. Now the bolt no mpi stamping which they claim that it is , so that usually mean its random batch testing at best . Worth the $129 ? I would say yes since they are on back order most everywhere. The test will come when we start running it . One thing I did notice is every split in the gas rings were lined up and not turned to keep gas from leaking thru. Not that big of deal to fix but almost certain to cause a problem .
