The title says it all. This bolt is dimensionally correct (verified with calipers), but the enhanced gas ring is dimensionally smaller than the standard diameter of the normal three gas rings. It slides loosely in the BC. No bueno! I had to replace the rings to get it to work. So for the price, I could have orfered a complete BCG by another manufacturer. Instead of having to enhance the "enhanced" bolt with standard parts.

Just fyi, fellas, JP’s smaller diameter gas rings are, in-fact by design. It spooked me too when I first got my JP LMOS, & I even replaced ‘em when I saw it wouldn’t hold up to the ‘stand test’ & the bolt dropped straight inside the carrier. But upon READING the literature that was provided (at least w/the LMOS) it says specifically, “it will not hold its weight upon standing the BCG vertically on the bolt face, which IS by design..” This is all part of JP’s proprietary engineering & uniquely smooth operating internal products. My LMOS system runs smooth as silk & I couldn’t be happier.

I'm sure the bolt will be fine but you would think that if you spent this kind of money on a premium bolt that they would have their act together. The one-piece "enhanced" gas ring was too loose and wouldn't even hold the weight of the carrier. Swapped it out for standard mil-spec rings, good to go.
