On one of my cheap air rifles, Crossman TR 77, I have a UTG Leapers 4-16x44 that's working good! No problems at all. My other, a Crossman Fire, not so well. The CenterPoint scope that came with the rifle was junk! I mounted a CVLife 6-24x50 that lasted about 500 rounds and it fell apart. I have a Hawke Frontier 30SF 2.5x15 that I was planning on trying. I contacted Hawke and they said this scope should be good to go, the reticle is etched. You guys agree?
