Things I liked:Excellent gun. Light weight to carry. Much lighter than most guns in its class. It IS a rifled barrel, not smoothbore according to Crosman's 2011 catalog entry (www.crosman.com/pdf/Crosman-2011-Catalog.pdf).
The gun is a solid beginner's rifle. Would recommend for any age group. Easy pumping, very lightweight, accurate shooting. Granted, i haven't mounted the scope. Open sights are probably what most starter shooters should concern themselves with anyway. Considering this rifle is currently listed as only $10 higher than most 760 variants, and the 664gt comes with safety glasses, paper targets, a scope, a tin of 2 types of ammo (100 BBs + 100 pellets)... it makes for a great starter kit and a great gift for giving any new shooter, too!
Oh, I recommend getting the Daisy zinc-coated BBs. If you wanna shoot BBs thru a rifled-bore barrel, that is.
Bought 2 of these, plus a Remington Airmaster 77. I am not ashamed at all to bring the 664Gts out alongside that Remmy or my two Stoegers (x20 & x10 .22 cals). Things I would have changed:Wouldn't change anything about the gun itself. PA needs to update their listing for it, tho. It IS a rifled barrel. Unlike what some previous reviewer stated, it is NOT a 760 variant. The powerplant is slightly stronger (664GT = 680FPS = BBs/645FPS = pellets... vs... the pumpmaster 760s: 625 =BB/600=pellets). What others should know:Be sure to get Pellgunoil for your pumpers. The two 664GTs I purchased were ok from the start, but the Remington 77 was dry as a bone when first opened. The oil made it so the gun held air when it wasn't doing so at the start.
this gun must be one of the best kept secrets goin on in airgunning right now. What a gem! And coming as a kit, with all those extras (ammo, glasses, targets, scope!), is just a pile of cherries on top to an already bargain priced rifle!
Things I liked:Nice heft to this rifle. Pumping is not hard at all. Doesn't need more than 5-7 pumps for general target practice, so a person won't wear themselves out too fast from multiple shots taken. Accurate! Wish the front sight was true iron and not the fiber optic. It's too big for what it's trying to do. Things I would have changed:The silver barrel shroud (surrounding the true inner rifled barrel) is not attached to the inner barrel. That makes it so the rear sight can move around. This is NOT a defect. It is a flaw in the guns original design.
Another design flaw is the fiber optic front sight. Sighting in on a target down field is like centering a tea saucer on to a dinner plate.
I learned how to shoot on open sights, as I feel everyone should. But that was years ago, and fiber optic is now the norm for it. If you're going to shoot further than 15yrds, then you'll pobably wanna scope the gun. What others should know:The silver shroud needs to be anchored or you'll never be able to target anything using open sights. What i did to correct this is loosen the screws on the receiver and shimmied some metal tape on to the shroud itself. The tape acts as a shim, making it so the silver shroud has zero movement/play whatsoever. Rock solid, and the aluminum tape is as sticky as duct tape, but without the cloth/fiber part.
Also, if you buy a remanufactured model (as did I), be sure to oil the gun right away with Pellgunoil. I don't know how long this gun sat around before I bought it, but the pump arm had no resistance the 1st time I tried to pump it. Oiling it, giving it an hour to sit, and then trying it again fixed it up right away.
Great price for an excellent gun. Recommend!
