5 of 5 Wonderful Upper/Great Shipping and Service! September 26, 2020
Reviewer: Shooterrex from People's Republic of MD United States  
AR-15 Part sent this splendid upper wonderfully wrapped/ packaged and with bolt carrier and charge handle installed.  It arrived quickly to boot! This is an absolutely beautiful and highly effective upper assembly and it's worth every penny! My first 3 shot group went into 1/2" at 50 yards using bulk Federal ammo and a cheap red dot sight. I was amazed! It is lighter than what I'd call "target grade" but shoots as well or better than any "target grade" out there- truly impressive! Thank you AR-15 Part and Wilson Arms!

Reviewer: Anonymous Person from Miles, MT United States  
I was told that your company was great to deal with and products were reasonably priced.. That is an understatement, the order was placed on a Thursday and arrived at my door the following Tuesday and was exactly what I wanted. Well packaged in beautiful condition. I highly recommend you to anyone interested in hunting and shooting. The parts assembled perfectly and it shoots even better than I expected. In fact my son who already owns several AR firearms was so impressed with the 200 yard group that he ordered one exactly like it.. so refreshing to deal with a company that is what they claim. Thanks for your service.

5 of 5 Well worth the cost May 31, 2019
Reviewer: Dan S from Fairless Hills, PA United States  
I built an AR a few years ago and was never satisfied with the accuracy. Last year I upgraded to a heavy barrel from BCA and was even more disappointed in the accuracy. I upgraded the trigger to try to help but it didn't do much if anything. Tried heavier ammo for the 1:7 twist barrel, slight improvement, but still not real good, close to 2-3 moa.  Installed this upper and using the same 68gr ammo I used before I was stacking shots at 50 yards (was raining and was more or less trying to sight in quick). The previous barrel/upper combo couldn't come close to doing that, even at 25 yards. Happy with this upper and the service I got from the website.
