Wondering if anyone has dealt with CAA Tactical? The first time I called to ask a question about the G3TUBE, specifically what buffer it used since I can't find the "G3T-REC" on their website as listed in the G3TUBE description. Seemed as if the CS rep on the phone didn't have any idea what I was talking about. Emailed them thinking maybe that would work, but the reply I received was "I know we have shotgun recoil reduction but not sure if I have seen the G3". Anyone know about the G3TUBE? Has anyone gotten an answer to any question asked of CAA?
