Well this is probably nothing worth posting but I have formed an opinion so I might as well share it with the world. I have a Turbo tuned Gamo,Viper that has become a real tack driver. I had been using a Leaper's 5th Gen 3-9x40AO scope on it. And I really didnt have any gripe's about it accept for the slightly crooked crosshair at the top of reticle and the close eye relief.I had baught my Dad a Centerpoint 4-16x40AO for his Target shotgun(Turkey shootin) and it is by all accounts almost identical to a Leaper's scope,but after really lookin at it I realized the eye relief is much more to my liking and the crosshairs are straight LOL. Seriously the Centerpoint has a better turret system IMO they have a extra lock ring that locks it by finger instead of having to carry that 1/8 allen wrench round with ya,it also has the allen screw to reset 0 with if needed. Best of all the Centerpoint are a little cheaper, Their 4-16x40 is $69 at wally world and the Leaper's 3-9x40 is a bit more. Both have Emerald coated lense's and flip up scope cover's,both are green and red illuminated,which I think people rarely use anyway. The Leaper's does come with a sun shade,but then the Centerpoint comes with a darn good set of scope rings (for weaver mounts) The Centerpoint has 100% warranty against fog,waterproof and shockproof as does Leaper's. Also the Centerpoint is designed by Crosman airguns so it is tested with some of the harshest recoiling airguns. To summarize, both scopes are very worthy of any airgun or firearm for that matter,but the fact is after really scoping out both brands I have baught another Centerpoint to use on my Viper,cause Dad wasn't givin his up. I guess this sound like a review but I just wanted to point out a few things as I'm sure some of you are deciding What scope your gonna put on that new airgun ya just got. And I have owned many,many scope's from $100 NC Star's to $600 Bushnell,Elite's,Nikon,Monarch to $1000 Swarvoski and I have gathered some input along the way. I will say that the technology now day's has allowed the smaller companies with more economic priced scope's to really narrow the gap in quality between the cheap and ridiculously priced scope's. But I just see the Centerpoint a slightly better value,with that said I have never even looked thru a BSA airgun scope that may compare in price. Some people sware by them but I was never impressed by thier non-airgun scope's so I just wouldn't buy one. Either way ya go you are gonna like the optic's you get per dollar,both are a good value and from what I can tell in all power's and size's.AKJC1977
