This AR-15 lower parts kit uses high quality American made parts to ensure performance in your AR15. If you are looking for a lower parts kit to use with an after market drop in trigger, this is exactly what you need. Why Choose DoubleStar Lower Parts Kits instead of the Other Guys; DoubleStar uses only the best parts to make their lower parts kits. An advantage to the kit is the use of coiled steel spring pins instead of the standard split roll pins. Not only are they easier to install, but they also flex outward once installed giving them less chance to work their way out. As a bonus, DoubleStar includes an additional takedown detent and spring in case one flies away during installation never to be seen again. All parts are American Made. The real question is why would you choose anything else?
