4 of 5 Solid 450 bushmaster upper May 1, 2020
Reviewer: Rhett Lee  
Love the upper, functions perfectly, no problems (I’ve only had it for a few weeks and haven’t even put 100 rounds through mine yet but it’s exactly what you’re looking for if you want a 16 inch bushmaster

5 of 5 Shipping and Inspection November 18, 2019
Reviewer: Reid Z from Frisco, TX United States  
Shipping was very quick, however, I am local to the area if AR15part.com. Upon visual inspection, everything looks good. Coatings are uniform, barrel and handguard are tight, brake is properly clocked. Cleaned and oiled. Assembled to a lower, hand cycled rounds just fine. Plan to shoot in the next week or so and will peer-review with more actionable information.
