This product was probabally the best thing that I could buy for my gun. I have it mounted onto the roof of my regular cab ford f-150 and it works great. I installed a kill switch before the momentary hidden lock release so it's even more secure. The lock works perfect every time and a theif couldnt access the rifle at all without a blow torch! only complaint is that the barrel rattles in the barrel lock-up when going over big bumps, hasn't affected accuracy yet but I found that putting a tube sock over the barrel helps a lot. Pipe insulation might work too. Overall an excellent product if you need a vechicle gun lock!
