I started with the cheap Argos 6-24 gen 1. It got me to 1,000 yards no problem. I doesn't have a zero stop and the glass is not great. But it works. I now have 2 Helos Gen 2s. One is on a 22LR and the other is on the 243. The glass is better than the Agros, it has a nice zero stop. Pretty good amount of travel. I took the 22 to 600 yards. The 243 has been to a mile. I do not beat on them too bad but they have both been to matches, the 22 mostly. They work really good, the cost is pretty easy to justify. Lots of people on here will yell about buyng chinese shit, that part is up to you.
