My son has an older Chimunk Rifle and he lost the steel front sight off of it this spring (whacking brush as he rode his snowmobile). Keystone bought out the Chipmunk maker so I emailed them regarding replacement parts. They were very quick to respond with ordering info and prices. A quick call to them and $10 got me a new steel sight and screw mailed out very quickly. I was so pleased that I didn't have to settle for a plastic sight and that they were so prompt. I'll lok tite this one on.
