When putting this upper on a lower receiver, would that make the rifle a SBR?

Matt, member, from CA, United States, asked on April 18, 2024

Is the muzzle device properly timed before it's pinned and welded? Don't want it to have a loud ringing.

A
Answered by Zach, member, from IA, United States, on March 11, 2025

Optics planet gets it directly from DD so unless Daniel Defense goofed it should be timed properly.
