LE6943CK
Great lightweight upper thanks to the short barrel and monolithic design. Flip-down sights are very convenient when using red dots and optics. Metal quad rails are comfortable to tightly grasp and hold; no sharp edges or corners. Barrel profile slims down to 0.61" after the front sight. Still plenty of shoulder meat for muzzle devices and silencers.
