Do not shoot steel BBs at hard objects or water. They will ricochet! Remember to wear safety glasses. In fact, 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.


If you like the black rifle look and want to shoot semiauto long guns, then add this pellet/BB repeater to your gun collection.

The Winchester model MP4 CO2 rifle shoots whatever ammo you've got. Steel BBs and lead pellets aren't in short supply like firearm ammo -- and a lot cheaper, too! So, load up your rifle and commence to shootin'. Because this really delivers a lot of power downrange, the gun uses two (2) CO2 cartridges at a time.

Our tech department has done some velocity testing of the Winchester MP4. They got 550 fps with pellets and 450 fps with steel BBs. There were times when an occasional pellet would reach 600 fps.

Things I liked: Quite realistic. All options for the real M4 fit well except the pistol grip. Works well and at over 200 shots I have had no working problems. It is fun to shoot. And it has plenty of power.

Things I would have changed: I don't think I would change anything. Maybe adjustable open sights but, I bought after market sights. They look cooler.

What others should know: I have just sent the MP4 back to Daisey. I was getting at best 2.5" groups at 20'. Pyramid recommended I talk to Daisy and Daisy issues a shipping label to have it returned. It should be 1.5" groups at 33' at worst they said. Both Daisy and Pyramid were so easy to deal with. I was taken care of in about 10 minutes. All you out there must understand, most of these guns have been shipped 1/2 way around the world before you get them, you are going to get a bad one once in a while. It's how they make it good that counts. I will update my review after I get my gun back.

Things I liked: Just like the other reviewers stated, this rifle is too much fun to put down. Fires as fast as you can pull the trigger.

Things I would have changed: Nothing.

What others should know: Sometimes it will misfire as others have stated but if all you're doing is plinking or target shooting, just clear and continue the fun.

Things I liked: i like the power and accuracy and the possibilities to add all laser/flashlight, hand grip etc.

Things I would have changed: Well the magazine should be bigger.

What others should know: Um. The barrer screws are bit loose so i suggest to tighten them to make it a bit more balanced.
