Does this upper include a BCG or charging handle?
No — the BCG and charging handle are sold separately as an add-on.
Why a 20″ barrel instead of 16″?
The longer 20″ barrel with rifle-length gas gives you a higher velocity, softer-shooting platform better suited to a fixed-stock DMR or precision-style build.
Will this fit my AR-15 lower?
Yes, it’s a standard mil-spec AR-15 upper and drops onto any mil-spec lower receiver.
What’s the barrel finish?
Phosphate coated, a durable mil-spec finish that’s more corrosion-resistant than bare steel.
Is this upper fully assembled?
Yes, the upper itself is fully assembled — only the BCG and charging handle need to be added to complete it.
Is there a longer barrel option?
Yes, see the linked 24″ version above if you want even more reach.

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.

Could not be more impressed fired about 150 round not a miss , great piece of equipment.

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.
Michael D Van Alstyne (verified owner) –
Very good upper for the $. Was light for a 20 inch set up. I was impressed enough that I justified buying another one.
Al K Parker –
Good product

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.
