I'm looking to get my first pcp. This gun will be solely for pest control. 35 yards max rabbits and chipmunks. I want a PCP because I am hesitant to mount my sightmark wraith nightvision scope on my break barrel. I'm leaning towards a umarex notos. For the price are there any other guns I should consider? I also plan on hand pumping as I plan to shoot less than 50 shots per year. Any advice for hand pumping? And as far as cleaning the barrel, do I need to use special cleaning solvents or flip the gun upside down when cleaning? I don't want to ruin anything.
