Hey Guys this is MIke Jr from Ottomanelli's,
Karl we at ottomanelli's wanted to follow up with your concerns with your Tavor. We are sorry that you had to drive up from a distance, we thought giving you some free ammo would have helped somewhat. However let me cover the issues at hand. First off the magazines are pinned with a rivet. For instance when an LWRC .308 REPR (roughly $3800 rifle) comes from the factory, all the magazine has is a rivet through it to make it 15 rounds NJ Compliant. So a magazine with a rivet is compliant per the manufactures. As far as the muzzle break in NJ semi auto rifles can have two evil features one on a Tavor the detachble mag and the barrel. As for the soldering issue it does not have to be visble, silver soldering is not visible on most factory rifles because it is done internally.
Please if you have any other issues, call us. We aim to please and want to make sure all our customers are happy.
