What is the Difference?

One of the most common eye catching differences between high quality and discount parts its is the overall "fit and finish." You do not have to be a seasoned professional to quickly see the difference when side by side. Excellent fit and finish is an important consideration when assembling the parts and the functionality after installation. To be able to truly trust your build, you want to know the parts slid nicely into place and fit properly without having to be forced or altered. 

As we select a quality lower parts kit, we also pay some mind to the materials used to create the components. We look for detents that shouldn't corrode. We also look for high-quality springs (made form spring steel), good roll pins, and smooth, crisp triggers.
