Helpful Positive Review Holosun Green Dot by machinist419, Verified Owner, July 1, 2025
Great cheap dot for a PCC! I even went out to 100 yards and shot steel with it. It’s definitely a fun little dot!

Sighted in at 50 yards with 10 rounds. Brightness is good and clarity is great. Gold is easy on the eyes but no compromise to the effectiveness.

I purchased this as optic for my low budget build and it’s great optic. I like that it sits a little higher than sig Romeo 5.
