Yep..... I've used a 6X24 Vortex Crossfire on three rifles and used it for more than a year. I've shot well over 500 rounds with it on a 270, about 250 rounds on an '06 and over 300 on a 22-250. It has functioned perfectly. It holds zero with absolutely no issues. It hasn't been "babied" at the range or in the field...
I purchased the scope on a special SWFA sale for just $99 dollars and I don't believe I've purchased a scope in that power range that I've liked so much, even those at considerably more money.
The glass is surprisingly bright and clear although not quite to the high optic level of their much more expensive Diamondback or Viper lines. My Vortex scope has been used often in extreme weather conditions (very warm to very cold to warm again) without fogging or failure.
When the almost unmatchable Vortex lifetime, fully transferable (even to subsequent owners without a receipt), no questions asked warranty is included in the equation they become irresistible, IMHO....
I'd have to add that the 6-24 scope has limited usage in a typical varmint hunting environment (too much power and an inadequate FOV for moving critters). A 2-7, 3-9 or possibly a 4-12 Vortex Crossfire would be an excellent "best-bang-for-the-buck" scope, IMHO.....
You've gotta check them out, hands on, to truly appreciate Vortex's high quality for the price...
I did and I was convinced!!
