"Great sight so far! Great sight picture, comes with a rubber cover, an allen key for the sight, a lifetime warranty, and thread seal.

I'm just gonna list some pros and cons to make this quick

Real sight
Comes with thread seal
Comes with an allen key
Comes with lifetime warranty
Feels extremely durable
Battery lasts 1000 hours according to the desc
Sight has 11 brightness settings.
Generic T1 sight so like 99% of mounts fit.

Red dot is a bit blurry
The brightness adjustment is extremely tight and takes some force.

Overall this is a great sight for the price (89.99 at time of writing). I would buy this over literally any crappy airsoft spec sight, even if you just play on weekends or whatever occasion.

"Great micro dot for the price!
This is a real steel sight, so I knew it was gonna be fine for my GBB.
I have this mounted on a Zenitco B19 on a GHK AKM for reference.

Solid build, I've smacked this thing against concrete walls, dropped it in the mud, and put it through hell, zero has held.
Doesn't wiggle when attached, once its on, it's going nowhere.

Maybe its just mine, but on the windage knob, it says turn clockwise to move the dot left, but it actually moves right.
On bright days outside, even on 11, the highest setting, it's sometimes very hard to see the dot when aiming at brighter colored objects, like a light grey building.

Overall very good and very inexpensive, would recommend.

"The Primary Arms red dot optic is an excellent optic, for only $89 your pretty much getting the best T1 clone on the market. Its a significant upgrade over the Avengers T1($50)
