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: I love the M4 for its lightness and comfortable to shoot, easy to pump and sight in, and shoots real smooth with no recoil which makes it very accurate very happy with the M4177.

Things I liked: The adjustable stalk is nice.

Things I would have changed: Size and ease of use of pump mechanism is awkward and difficult

What others should know: BB autofeeder jams easily

      • David from USA:

        Because this rifle can go above the 495 FPS, you will need that special license Canada requires
