Primary Arms ROCKS! Check out their Labor Day Sale.
Ordered a Vortex Viper 1-4 with added flipcap covers for $9.50 each, but the rear was out of stock. So told them to send it when it is in stock and bill me. After I finalized the order, I checked my email and they are having a Labor Day sale with a coupon code for a free Dewey cleaning adapter. So I emailed them to see if I can use the coupon after the fact.
Garrett at PA not only added the Dewey adapter but also sent the flipcap for FREE!
I've bought from them 6 times now and all transactions are perfect. They got the best customer service ever. Thanks PA!
