will this work with PSA AR 15 freedom classic lower flat dark earth?
Bruce R on Jul 5, 2018
BEST ANSWER: Bruce I purchased this upper with the 7779346 lower and they work perfect.
What kind of sights will work with this upper? Can you put a red dot on it?
Mikie on Jul 12, 2018
BEST ANSWER: I put a Holosun red dot on it. It works great. Any red dot will work if it is high enough to 'co-witness' with normal AR sights. You can purchase a flip up sight for the rear.
What else would I need to make a complete gun if I bought this upper and the SKU: 7779346 lower?
Sandbed on Aug 13, 2018
BEST ANSWER: You would need a rear sight and maybe some type of optic. Other than that you're golden. It's a good set up and well worth it.
Finish on the barrel?
ALTON L on Jul 5, 2018
BEST ANSWER: It is nitride treated. It is not coated thus minor machining marks are visible. I would call it a semi gloss finish. Since the entire barrel is nitride treated the bore is also nitride. Nitride is more accurate and superior to chrome lined... for civilian use. I am a fan of nitride. Gears in heavy machinery are nitride treated for a reason, they are not chromed. It is worth doing some research on the subject. Be careful of opinion vs fact.

Good price for a good product
Good quality for the price, if you're looking for a decent upper for plinking, target practice, or home defense, this is nice for a entry level ar build.

Purchased this upper on Saturday, received Wednesday. Very impressed with the shipping time for this product. It arrived aassembled with all the parts. Clearances are tight with my Ruger lower and fit perfectly, headspacing seems good. I have not been to the range yet, but first tests with cycling rounds, etc. have been good.
