Works well

The drum hole was a little tight and had to be worked in a bit with a punch. Other than that this is solid!

Nice kit, but the sight apertures are soooo tiny

Overall happy with this kit. Assembled in a Luth A1 and it went together pretty easy (that drum roll pin is a huge PITA though). Dunno if it's normal with A1s, but both sight apertures are incredibly tiny and hard to use. Unless you gotta be clone correct, or this is a factory goof, I'd throw an A2 aperture in there. OEM on these is Luth.

The one hole that isn't centered is because when you flip the sight, it moves on the screw. The hole is offset to make up for the movement.

A1 rear sight not centered, used an A2

One of the apertures for the rear sight is not centered. It didn't affect me as I was going to use an A2 rear sight. I highly recommend using an A2 rear sight, they're better. [PN: URPA2RSAP] Just a heads up, order some extra pins for the rear sight as well. I split the one during installation. It's the same pin that is used for the standard AR charging handle.
