Automag 68 classic, 88ci 3000psi crossfire compressed air tank, air america vigilante regulator, RT retro valve, a.n.s. venturi bolt, 10" dye stainless steel.
The sight is very durable. I've had multiple balls hit both the sides and the lens, without any affect on the sights performance. Also, once I set the proper zero, the sight required less tunning than the lesser ADCO models. The ability to change the brightness of the dot for high lighting, is also a plus.
The further the sight is adjusted upward, the more of the insides are exposed, which is expected, but in my case this made the sight tend to flop from side to side, nothing big, but this is not the case with the E-dot sight.
This is a great sight for the financially challenged, and is defiantly worth the money in performance. Again, it is very durable, and will last for quite a long time. If your willing to spend the extra scrill, I would go with the E-dot.
