Need a second opinion on a CC SA20 upper receiver I have. There seems to be an extra slot in the Pic rail (14 total), some material removed where the charging handle meets the upper, different lettering in the rail slots, and a chamfer at the very front of the rail.
Personally, I like the modifications, but what type of CC upper is this? Def not a standard SA upper.
