Milspec is a nice start. Having the certainty it was individually tested is reassuring for some. If it was a duty gun, sure.
Sport and hunting, it's a premium service that only guarantees they have a documented reason to reject one. Batch testing of a few for the lot produced is standard on most guns, cars, cameras, you name it. Only electronics ever get run in to make sure, because you have to ring the circuits. Nobody individually tests, MPI's and xrays every spindle, hub bearing part, crank, rod, and piston on your car. Lots more people get killed from user error, not parts failure, tens of thousands more than a gun failure.
For those pushing milspec, please cite the tests your personal carry handgun passed - barrel, MPI? Slide or cylinder, xrayed? What package of tests handchecked off in original blue ink did you get attesting it was made to what official standard?
By the way, isn't a nitrided ion bond bolt supposed to be better than parkerized? Barrel too? Milspec is a compiled list of how things were done 20 years ago. It won't be the same after the Improved Carbine comes out. All those "milspec" M4geries will be substandard.
Please, I messed with Army gear for 22 years, milspec isn't the end all be all. It's why the Army now prefers to buy off the shelf, and we are better off for it. Ask the troops wearing Danner mountain boots and softshell jackets in Multicam if they would like to go back to milspec issue stuff.
Not so much.
