EOTech 512


The 512 has a large to house the AA batteries. Longer battery life than the others. Easy to turn on and off. The magnifier is great. Easy to remove by hand.

Eotech 512 and magnifier


Great optic and magnifier. But primary arms customer service is excellent. I always check on their website first for my firearm needs.

Eotech purchase


Hands down the best service from an online retailler I have ever had.

Excellent deal


This is one of the greatest deals available for a holographic sight.

Excellent Value


The sight came with a 3X magnifier and mount ($60 rebate as well) making it an excellent value. Fast shipping as usual with Primary Arms, LLC....

Great customer service



The product and the service provided by primary arms.com exceeded my expectations. I was very pleased with My overall experience

Great deal


Can't believe I got both for such a low price! I only wish it was back in stock

Great Deal!


PA charges the same amount for the EOTech 512 as most other retailers but they also include a 3x Magnifier and mount for free! Best deal on these optics on the internet.
