Can someone explain the difference between these complete AR 9 Uppers? Descriptions are the same but there’s a $10 price difference.
5165451063 Gen 4 8" 9 mm $369
51655104656 Gen 4 8" 9 mm $379
Thanks in advance.

The only real difference I can see is the thread pitch. We are getting away from the 1/2x36 thread pitch for our 9mm platforms as much as possible right now, that might be why one is priced a few dollars higher.
That makes sense. Thanks Josh! I didn’t note this difference in the details.
Not a problem. That detail, and the design of the rail system are usually the answer for these types of comparison questions.
