I have put 3 of these together in the past year. Each one shot 3 rounds almost touching at 50 yards with the flip up sights. Functioning has been flawless from the start. Thank you Moriarti

I love this upper, quickly became my favorite rifle to shoot.

Looks, feels and shoots amazing. Having lots of fun with this one! No issues after several hundred rounds. Shipping was fast (3 days) and quality is great. Arrived just as described. Thank you!
