| I was just reading up on the JP BCG. They state their enhanced bolt uses Chromium Nitride. Is this a coating or similar to other nitriding like their QPQ carrier that is a metal treatment? Also I think I remember their bolt used to be Nickel Boron. When did it switch? What is the current consensus on the JP FMOS BCG for overall performance compared to the mil spec options like BCM? Thanks |
| Is their choice of sae 9310 steel a good choice for a bolt compared to mil Spec? Is the FMOS BCG a suitable choice for a range and had defense type weapon or is it more of a niche higher end type item? Would you trust it as your only BCG if your life was on the line? Is the bolt coating in danger of flaking off at some point? Thanks |

S7 is superior to both, but is fragile and particular during heat treat. IE if it is done with a fraction of error, the bolt will crack, break, or fail miserably. |
