DoubleStar uses high quality American made parts to ensure performance in your AR15. Why Choose DoubleStar Parts instead of the Other Guys; DoubleStar uses only the best parts to make their lower parts. Lesser Parts use metal injected molded or improper steel to cut costs. The lesser part will wear at an extremely high rate and need replacing sooner. DoubleStar parts are made to last for the lifetime of the weapon.
