Uppers

Uppers

All upper receivers not chambered in 5.56x45 or .223 Remington come with one (1) caliber specific magazine. Capacity may vary depending on your State's laws.

When ordering an upper reciever unit please keep the following in mind: All complete uppers sold on-line come fully assembled, headspaced and test-fired. While each upper is made to mil-spec standards for dimensions and tolerances, uppers may fit differently on various lowers. Some may fit tighter than other, some may fit looser. Some may require minor fitting based on tolerance stacking. Each upper comes with a lifetime warranty and a 60 Day Satisfaction Guaranty. Please see our Warranty page for details.
