PRIMO customer service
ADDAX is number one in California!! I emailed them because I did not get my order but found out the reason is some items I ordered were on back order. They emailed back right away and answered any and every question I had. I will definitely be buying more from them…..just waiting for the new gas piston uppers, in the mean while, I told them about a current GPU upper I had with loose fitting to my lowers (long story) but they told me I can drop it off and they will replace it with another upper assembly for a low cost to me…..now that’s service you can’t beat or find in many dealers these days….keep up the good work and service guys.
