Things I liked: I like the weight of this rifle, and the fact it is an adult sized rifle. The accuracy is outstanding with this .177 rifle. After breaking in the barrel, it now consistently shoots 10 shot groups of .75" or less at 25 yards.
Things I would have changed: To anyone who has one of these, the most obvious thing that's bad about this rifle is the trigger. It's terrible. Mine had no adjustability for travel and the pull is a mile long. But I'm used to it now. GAMO, if your going to sell these guns with scopes mounted, chuck your brand and put a real BSA scope on them. The crosshairs started to spin after 150 rounds or so. Chucked that thing and replaced it with a Center Point. All is good now.
What others should know: I was lucky to get an exceptional rifle. I bought a tin of Crossman Field Hunting pellets for break-in. After 350 rounds, the rifle started to shoot very consistent groups out to 40 yards with the aforementioned pellets. The PBA pellets shoot well out to 25 yards, but the groups open up greatly as the range increases. Clean that barrel as soon as you get the rifle. Mine was gunked up terribly. If you don't have JB bore cleaner, get some. I've been using JB for 30 years on everything from pellet rifles to M2 .50 cal machine guns, nothing works better. Use it properly and you'll generally increase your accuracy up to 50% with any firearm.
