I'd like to add to the increasing good comments from other Calgunners here.
I recently purchased a complete lower from a friend of mine and had it sent down to Riflegear. And just yesterday I was able to pick it up.
I am very new to ARs and the staff here at Riflegear wear very helpful. They answered all questions I had politely and professionally. They showed me some of the in/outs of my AR (I brought in a complete upper I had) and some basic maintenance.
Chatting with them was very comfortable. The customers in the store were also very nice and polite. You can tell that others were feeling the same way.
So, before I left, I purchase 4 PMags and get the party started!
