They rock !! I posted about 6 weeks ago. I took one too many pins out while trying to reposition the pin retainer clip and hammer pieces fell out. I put it all in a box and shipped it back to the factory. They not only put it all back together for no charge - they also added my +1 mag extension for me. If that wasn't enough - they did not charge me to ship it back !! I wish they made cars ! What great customer service !
