Canadian National Arms Complete M-LOK Upper (300 BLK)

In stock
As low as CA$557.17

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 a barreled upper.

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