So far so good. Got about 2000 pellets through it so far. Installed a scope stop, that solved the scope sliding problem. This is my first experience with a mag springer gun and it has taken me a while to get the hang of it. But overall I find the gun to be as accurate as I am! Seems to shoot the cheap pellets better than the pricey ones. It does, sometimes, have the annoying problem of shifting point of impact on me from one shooting session to another. It groups well but it may have as much as 3 in difference in point of impact. All screws are tight, scope is tight etc. Kind of annoying, since it doesn't happen everytime. Also, at what point does the piston and chamber need to be cleaned and lubed? And, are there any after market parts available, such as a seal kit, spring upgrade and better trigger. Anyone have plans for a simple spring compressor for disassembly? Sorry for the long post! catch ya'll later!
