Great company

by -

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

by -

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.

Durability tested

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.

Discounted 403B quality

by -

Purchased 2 of these 403B when they were discounted. Found both to have a lot of led washout and reflections inside the tube that make them very hard to use. Reducing the brightness doesn't eliminate the issue. Have always been satisfied with other 403B. Not sure why this batch had these quality issues. No matter what, you get what you pay for. Won't buy any more of the discounted lower quality units again.
