The tool craft bolt I received was awesome and was in my hands in less than 3 days .
The fit,finish is super slick and gas keys are properly staked so no worries there ! Plus the Toolcraft warranty is awesome but I doubt I’ll need it !

The reviews are right -- this BCG looks, feels, and works great. A few hundred flawless rounds so far with mild wear patterns and no change in functionality.

Beautiful black nitride finish. No tool marks. Looks to be as good as it gets with an unbeatable price, free and fast 3 day shipping. I'll be buying from Toms again.

I'm impressed. Toolcraft's finishing is much better than the PSA BCG's I own. There are no tooling marks and the nitride is a beautiful dark black. Quality and workmanship shows. It doesn't have the dull phosphate look if that's what you prefer, but it's functionally superior. 9310 bolt steel takes advantage of the latest technology. Their warranty is a bonus for sure. Tom's shipping was fast too.

I'm doing an AR build using a PSA lower and PSA M4 upper and I bought this Toolcraft BCG from Toms. You can't beat the price and a lifetime no questions asked warranty from Toolcraft, what more can you ask for!
