Thread: Review of the Holosun HS503GU Circle Dot (Black)

Quick Update.
I really like this sight. New ones should be back stock in another couple of weeks according to Ken.
I will get another one to have a play with on my AR-15s that's for sure.
The one on my 930 SPX is not going to be taken off.

So I put another 150 birdshot, 50 buck shot and 20 odd slugs through it today.
Not a single problem as you may have guessed.

I have never shot a lot of slugs over the years but after today I have a new respect for them after shooting a number of fist sized groups at 50 meters.
They are surprisingly accurate.
