    This upper is going to be for them wild hogs, to fill em up with lead. It’s much nicer in person, than in pictures. Changed out the flash hider for a nicer comp, couldn’t be happier. Daytona Tac. If you read this, I love you guys.

    The upper is amazing. Not the best quality but definitely good if you are just beginning to get into ar15s. My steel case ammo went through the upper fine. I would advice you to lube up the BCG if you purchase a brand new one.

    The only problem I had is after about 50 consecutive rounds the upper is blazing hot. (Which is typical) it just seemed a little above the average temperature.

    Very good upper for the $. Was light for a 20 inch set up. I was impressed enough that I justified buying another one.

    Just received 20″ 1:8. Great price. government style profile barrel, I had to adjust the foregrip to align with receiver, Adjust gastube, “Very minor” adjustments. But I am well satisfied with the product, shipping time(in current situation we are in), and communication. I will definitely give Day-Tac 5-Star rating. The Great State of Florida should be proud of Day-Tac, being a native Floridian living in Washington state, I’m proud of the way Florida has been handling the current advents and for Day-Tac’s support of my freedom and 2nd Amendment RIGHT! Thankyou!

    I bought one because of all the good reviews. My experience however is that when I mated the upper to the lower it was so sloppy and wiggled so bad there was no way I was even gonna try to shoot this. So I took the barrel off and put it on a bear creek upper and the slop went away. Maybe I just got a bad on but its trash on its mil spec tolerances. I just hope that the barrel is of better quality.
