I have three or four of them on rifles and have never experienced a single problem with them. Just to punish them (and me) I put one on my White Rifle and was shooting 460 grain conicals with 90 grains of Triple Seven 2f powder. Lets just say if a cheap scope was going to fail, that should have sent it on its way. The scope preformed flawless.

The glass is good, the cross hairs I really don't care for, but can live with it. My understanding is they are made for shotguns and muzzleloaders. The ProDiamond reticle identifies a turkey's vital zone at 40 yards and a deer's vital zone at 75 yards. Still, their parallax setting is set at 50 yards. Makes a perfect scope for where I hunt. Also they are easy to focus.

Semisane got me started on these things. He was talking one up and so I bought one just to destroy it. Well I am still shooting that scope. I have been so impressed I put them on other rifles and keep a spare one around should a rifle need a fast scope change.

Now don't get me wrong. Some of my rifles have Bushnell 3200, Nikon Omega, Nikon Pro Sports, Bushnell Dusk to Dawns, so I do shoot some high end scopes, but these Simmons are a cheap easy scope and fun to have on a rifle at my range.
