A note from Toolcraft
Toolcraft carriers are made from the best materials that can be purchased in the market today. Regardless of the coating you choose, the carrier that it protects is made the right way, with no compromise of standards using materials that are Made in the USA. There is the basic 8620 steel, a better grade of Gun Quality 8620 steel, an even better grade of Aircraft Quality 8620 steel, but then there is the best Aircraft Quality 8620 steel that is proprietary to Toolcraft only and no one else. These high standards of materials set us apart from the rest.
While some manufacturers have compromised the Mil-Spec standards of machining just to add to their profits, Toolcraft has stayed loyal to the Mil-Spec machining standards since the beginning.
All Toolcraft carriers are post-heat treat machined to remove any distortion that has occurred during the heat treat process. We first grind the outside rails that are in contact with the upper after heat treat. Next, we machine the inside bore where the bolt is doing the work. This ensures the gas rings are not damaged and that the weapon cycles and charges smoothly. These standards are not just met, but we exceed them on every operation during the machining processes and this effort gives our carriers a superior finish with no machining lines.
Toolcraft machines each carrier to last for thousands of rounds and that is why we can offer with confidence a Lifetime Warranty on our products. These standards have given each consumer the confidence that when they use a Toolcraft bolt carrier group in their weapon, it will do what it was created to do, round after round for years to come.
Toolcraft products carry a lifetime warranty.
Simply put...Should any of our products fail, return it to us for a brand new replacement.
