Good upper receiver - Geissele USASOC AR15/M4/M16 Upper Receiver Complete Group

Honestly haven’t shot this particular upper,however, this is not my first URG-I. Previous URG-I had Daniel defense barrel and a generic mil spec bcg.

Upon first inspection fit and finish seems fine. Bcg shows some tooling marks but the actual bearing surfaces of the carrier are flawless and these marks are even visible on the geissele website. Rail is aligned. Gas block aligned. No complaints about the assembly. However…

This upper was packaged horrendously. This isnt my first upper. This isn’t even my first upper from optics planet. But this is the first upper that has shipped in its original box only. The geissele box is the box it came in broadcasting to the world what was inside and coming to my door wet with rain.
