Things I liked: Mil-dot reticle, ease of adjusting "clicks", large 50mm opening for lots of light, illumination is somewhat neat as well.
Things I would have changed: Adjustment for parallax setting. No matter where I put my eye, there is always a blacked out area.
What others should know: This scope is good for the money and can take a beating. My rifle/ scope combo dropped off of my lawn furniture, striking the metal arm of the furniture before slamming onto the concrete porch. Besides a few scratches and taking about 10 shots to re-zero...this thing took a licking and still works great. Due to the heavy recoil from my Gamo CFX (Air Venturi model), the scope turrets loosen themselves after every 10-15 shots so keep the allen tool handy to retighten.
Things I liked: Gas piston versus metal spring, knowing that this is just an air rifle...but with 22 rimfire velocity, build quality, accuracy.
Things I would have changed: This is no kids gun, I am 5'11", 200 lbs. and of a stocky build. About 40-50 shots into it, this thing wears your arms out! The trigger also needed to be replaced...way too heavy from stock. I ordered from Charliedatuna.com and it took less than 5 minutes to install. A great upgrade and much needed if you want real accuracy.
What others should know: This is a heard hitting, accurate air rifle. I have tried numerous different pellet weights, shapes, etc... Mine tends to like the Gamo Magnums the best and will hit the center of the bullseye at 50 feet all day...as long as I lay off the coffee! I wanted pro-marksmanship for a lower price and I definately got it (after the trigger upgrade) with this rifle.
