Received in short time as per the usual with KM tactical. Excellent product! It was the final piece of a pistol build that meshed so perfectly it’s like it was made for it. Haha. I already have plans to buy two more for my next two builds.

Nickle boron, is the only bolt assembly I need.
It cleans up so easily, compared to the “other” bolt assemblies that come standard.
Well worth a few extra bucks they cost. You can’t go wrong.
I’ll need.to get one more soon enuf.
Thanks KMTACTICAL
