  1. Great BANG for the buck
    Mated a 10.5 inch complete upper with an Aero lower and the fit/finish is phenomenal for the price. A couple of machining dings but the overall value is killer!

You get:

You need to get separately:

Installation difficulty:

The suppliers for CNA have brought some super value, overstock complete uppers to the table that we just had to grab! These are made with American key components (like the BCG, Barrel and upper forging).

That's right ladies and gentlemen, these INCLUDE a head spaced bolt carrier group AND charging handle for about the price you normally see for just a barreled upper.

Drop in ready, just bring your own lower, mags, and ammo.
