Very well built…Worth the money!

by Dan McConnell, from PA, United States Written on January 5, 2025
Was surprised at the quality for the price. OP was great, fast shipping, fair price. Had a cracked scope cover(cheap) but that wasn’t their fault…Pull the trigger on this one, it’s a great family of scopes. Made in Philippines too, not China.
Pros:
  • Decent glass, good build quality, top shelf warranty
Cons:
  • None
Best Used for:
  • Hunting, Target/Range shooting
