Pretty sure some are true then again a good number are probably not. I was reading on a fishing site about a level wind reel a guy simply could not say enough bad about. I looked it up and for what it was selling for, I could not believe anything could be that bad so I got one. Just one sample but have three of them since. I doubt the bad mouther ever even had one!Too many Vortex horror stories for me.
I bought a Tasco Pronghorn years ago and put it on a 25-06. Recoil took it out, ring holding in the front glass stripped out. Had another Tasco World Class and put it on the 25-06 and it worked well for a long time. Also had a 4x Tasco I bought in Europe but don't remember what I had it on. Got to where I could afford better and got a better scope. Now how do I define better? Well in this case it looked better! Go figure. I got a new Vortex Crossfire 3-9x for a 243 several months ago but haven't had nice enough weather to go sight it in yet. Well did but rings I had it let the front bell and eye piece sit on the barrel and bolt. Recently got a new set of Vortex med rings and that problem is gone, just need to sight it in now!
