I'm sure I don't shooter nearly as many rounds through my AR's as some of you guys do, as my focus is pistol. I do use Toolcraft C-158's as my go to's for most of my builds. Numerous rifles with several thousand rounds each, none with problems.

We've heard before that very few folks make their bolt's in-house, instead sourcing from vendors. We've also heard from sources on here about different manufacturers using substandard vendors.

I'll continue to buy Toolcraft's until I have a bad experience or an given reliable data on specific failures.
