Looks and feels like an M4 firearm. Shoots either BBs or pellets, so you can use whatever ammo you've got on hand. Since it's a multi-pump, you can pump it up to 10 times to get higher velocities or less if you'd like to do some easy all-day shooting.

Get extra clips (same ones used by the Crosman 760 Pumpmaster) and load up so you don't have to interrupt your range time with a lot of reloading.

When you shoot steel BBs, do not shoot at hard objects or water. The BBs will ricochet! No matter what ammo you're using, remember to wear safety glasses. Everyone in the vicinity of the range should wear safety glasses, even if they're not shooting. Remember to remove all pets from the range before you start shooting.

Things I liked:Built SOLID. It may be plastic, but there are no creaks, squeaks, etc. Smooth pumping action. Comfortable to hold and shoot. Lightweight enough to make it easy to hold on target. No recoil means you can concentrate on nailing your target with ease. Standard picatinny rails mean you can really customize this gun easily.
Things I would have changed:For the cost, nothing whatsoever. This is a solid shooter right out of the box.
What others should know:I picked up the factory re-manufactured unit from this site and with only a minor adjustment to windage and elevation (1 adjustment to each) I was knocking over cigarette packs at 50 feet. The first thing that struck me about this gun when I unpacked it were the sights. As stated above, the gun is plastic, but it is solid. The sights are beefy and solid as well. They maintain accuracy and will not budge from zero, yet are easy to adjust. The safety is 100% manual. Set it back on after each shot.

Things I liked:Repeating action. Peep and post sights. Accuracy. Lightweight. It looks pretty sharp. The sight adjuster and clip fit in the fake magazine.
Things I would have changed:The trigger is awful. Make it auto-indexing. It needs more power. I wish they had built this on the 2100 power plant instead of the 760. The clacking during pumping is pretty obnoxious.
What others should know:This little rifle is an excellent first airgun for a smaller, newer shooter. The adjustable stock ensures that it will fit the smallest shooters and be adjusted to fit as they grow. The peep sights are a bit crude, but they provide an excellent sight picture. It will let you use bb's or pellets, and can easily be scoped. It is very light, and mine has been very accurate for the price. I get groups of 1-3/4" at 25 yards for 10 shots.

      The refurbished models may have some scratches, dings and nicks on them, but they are guaranteed to work. No, it has a lot of plastic.
