Things I liked:Accurate, powerful and nice looking. Things I would have changed:Nothing really. What others should know:The gun has a lot of oil in it, so it always diesels and would detonate every so often. Also, accuracy suffered after about 100 shots. This was remedied by cleaning the barrel which was very, very dirty. I used my .22 rimfire cleaning kit, but I was told to not use any petroleum based solvents or oil. I'm told to only use slicone chamber oil on spring piston airguns. The cleaning brought back the accuracy and the detonations have stopped. All is good for now.
Things I liked:This is an updated review. I like the accuracy of this gun even more now that I have found the right pellet. Things I would have changed:Nothing What others should know:After reading reviews of the Avenger and other Mendoza rifles, Ilearned that these guns prefer fatter .22 pellets. That's why when you watch Paul's video review you'll notice that he gets higher velocities with the heavier pellet. The heavier pellet in his test had a better seal in the barrel. Based on one of the recommendations I tried the RWS 14.2 grain Super-H-Point pellet. The barrel stopped smoking with the RWS pellets and groups became much more accurate and consistent. I don't have a chrony, but I wouldn't be surprised if velocities increased. If you're experiencing a lot of dieseling, detonations or more than one "flier" in 20 shots, then try the Super-H-Point or other "fat" .22 pellets.
Things I liked:Easy to intall, looks good and greatly improved my accuracy. Things I would have changed:Offer a smaller hole. What others should know:My eyes struggled with the stock iron sights on my Avenger 1100, but I didn't want the bulk and complexity of a scope. The Beeman aperature was the perfect solution. Shooting is very accurate and now I can see the target!
