Reddit reviews UTG Super Slim Fixed A2 Rear Sight

Pics of sight in link

Hey guys, quick question for those of you more experienced with AR-15 irons than I am. I just put together a super cheap, very basic AR for a trainer rifle and decided on the UTG Super Slim rear sight for the build. I didn't notice it when putting the sight on the rifle and zeroing (wasn't looking for it either) but the rear sight has some play, with a ball detent on one side. This causes the gap to be larger between one side of the rear hood and the body than on the other. There is a hole in the sight hood that does correspond to a hole in the body of the mount that looks like it may be a pin hole. When aligning these holes by pressure on the rear of the sight, it does sit flush on both sides. Is this normal, and is it possible I've lost the pin? In pictures of the sight I've found online I can't tell if there is a pin there or not. Do any of you have this sight? And is a slight amount of play in this area normal? Thanks in advance.


Edit: Sadly this didn't even occur to me...a pin here would prevent windage adjustments entirely so I doubt there's anything wrong. Derp. Still would like hear what you all have to say. Feeling kinda dumb.


Edit 2: Was wrong about the windage adjustment prevention. I really appreciate all the help!

Saw this recommended over on gundeals if you're looking for a permanent one and not a BUIS.

This and this will only set you back about $50.00 and should be compatible with your gas block mounting rail.

This was the rear sight I was planning to go with if I got a pinned front sight upper since I saw no need for a folding rear sight.

You can go cheaper yet, but they start looking a little sketchy IMO.

Edit: also, the kit you linked has the EPT trigger which is supposedly a good improvement over standard mil-spec. I was just reading a review today that put it on par with the ALG QMS trigger.
