Perfect Fit
This was a perfect fit. Some users complained it was not flush. Mine sits flush and works as advertised.

Great part!
Wanted a retro selector without the tick mark. It's exactly what it is. Finish was good and install was easy. Best of all, it works as it should. Buy it.
parts that work
No need to spend more, this part works. I will buy again.
junk
As mentioned in other reviews these are regular selectors that have had the tick on the off side roughly ground off. They took too much off, the opposite side sits below the level of the receiver. I've done this operation myself with a hand file and there is no reason to take so much material off. The machining in the detent pocket is also sloppy and rough, which makes these about as smooth to operate as roller skates on gravel. I bought two and tried them both with the same results, both are garbage.

It works. However, the finish is not high-quality paint/coating or parkerizing - base metal shines through. It appears as though a tick-mark selector was modified using a belt sander so it is scratched, 'sunken' in the receiver and not radiused. There are machining marks on the 'switch' side too. That side is positioned well off (credit card thickness) the receiver. Lastly, while the selector snaps positively in both fire and safe, it is very stiff between positions. I attribute that to the 'channel' width/depth between positions. The comparison selector in the photos is a standard Geissele. The finish/machining is identical on the three Brownell's selectors I received.
Just Like I Remember!
I built a AR just like the M16 I first qualified with in basic training! Just semi-automatic and with much tighter tolerances. My weapon back then rattled like a loose fender.

NO Tick Nope
As others have mentioned... Shaved too shallow for correct fitting on right side. And refinish was spotty.
No good
Rough grounded off tick mark. Like others noted, too much material taken off.
