The owner's manual states this is an airsoft pistol. It is not!

You can extract more accuracy from your Aftermath Mayhem .45 BB pistol if you mount a laser, tactical flashlight, scope and/or dot sight. The accessory rail (under the barrel) is a great place for a laser and/or flashlight. Put a dot sight or scope on the top rail, and you're ready to drill some targets!

When shooting a BB gun, everyone in the vicinity should wear safety glasses. Never shoot at hard objects. Steel BBs easily ricochet, so everyone in the area must wear safety glasses. Remember to remove all pets before commencing to shoot.

Things I liked: Bought this pistol for my Son for Christmas. Real gun feel and very accurate. We Plan on an upcoming squirrel hunt. I am sure we will be eating squirrel stew.

Things I would have changed: It would be nice if it came with spare clip.

Things I liked: I like the all metal construction. Has a metal magazine nice weight feels like a real gun,power and accuracy is very good at 33 feet, easy to load Co2 cart and lots of shots per cart. For an all metal shooter the price is very fair.I also like the look of the gun.

Things I would have changed: As always a extra mag should come with the gun. Adjustable rear sight would be great.Trigger pull is very heavy and should be much lighter.

What others should know: If you like to plink soda cans and plastic army men this gun is perfact.

  • tim from USA asked:

    I bought this gun a few years back and I love it!Its accuracy was awesome.The barrel eventually became worn in an oval and it lost its accuracy. BUMMER! I got it out the other day and when I put the co2 in it it all leaked out very quickly.I would like to get this gun fixed but Im not sure where to do that.Is there somewhere I can send it to get it refurbished?Or can I buy a refurbished one somewhere because they quit making this gun?
