kBob,
Here you go: I've included a pic which shows the C02 mounted in the magazine along with the provided hex key to tighten it into place. The magazine holds 18 BBs in a spring loaded slot on the front of it. SA only just like the gun it is modeled after. Sights are basic 1911, black, matt, front...black, matt 'u' channel in the rear. Once again, just like the old Colt. I was able to consistently hit an upright 4x4 post at 60+ feet and there are plentiful YouTube videos of these guns doing very well at 10 and 15 yds with their smooth bore barrels. The Daisy Copperheads sell for 4.99 at Pyramyd Air for 1500 and the Excites for 14.99 a tin for a similar amount. I don't have a chronograph but I have watched the videos and mid to high 300's for the lighter steel shot and 300-320 for the lead Excite shot can be expected. All in all, you should get yourself one of these. You will not be disappointed in the amount of fun per dollar. ;o)
regards!
