Red dot was lost in shipping or was taken by a porch pirate but primary arms replaced it and sent me a new one free! Will definitely buy from here again. Have not used the red dot yet so my 5 stars are just for the company
Great red dot

Can not beat the value in a Holosun red dot. Have a few of these on my rifles and rifle caliber pistols. This is a great value in a basic red dot.
Bought this red dot specifically to get banged up at the tactical games. It went through the ringer and came out fine, can't beat the price for the quality and reliability.

This is my go to red dot optic… I have this optic on all my home defense rifles… easy.. light weight.. and the shake awake with 50,000 hours of battery life ensures it’s always ready.
