Grey Ghost Precision Complete Upper 6.5mm Creedmoor 32.5in 22in Contour 1-10 5/8x24 M-LOK Black. 5 Creedmoor Upper is one of our most popular uppers. The weather resistant and light weight 6.5 Creedmoor caliber really shines in the CQB arena without a doubt. It really is amazing how a 6.5 upper can perform shooting this caliber out of a 22 inch barrel. Not only does the versatility of the 6.5 Creedmoor make it a great ELR round but it also lends itself very well to the rest of our .22 long mid length and coyote barrels that are on the market. The 22 inch length will give you enough extra room to mount a 22 inch barrel if you so desire. Due to the light weight of the 6.5 Creedmoor most shooters find the extra length to be a great weight savings as well. We highly recommend pairing any of our 6.5 Upper Receivers with one of our 22 inch barrels for the ultimate in flexibility and versatility.
