When purchasing Grey Birch Solutions or any other brand from eGoods365.com store, you can be sure that (a) you are purchasing from US based company with the most responsive and friendly customer service; (b) an authentic, not a counterfeit and not a refurbished product.

When Grey Birch Solutions designed their 10/22® pattern bolt assembly, they did so with three objectives. The first was to tighten and control head space to .002, which significantly improves accuracy and consistency of accuracy. The second was to improve the external coating, resulting in increased reliability and extended bolt life by resisting corrosion. And last but not least, making assembly and disassembly easier.
