Faux Acog

I got the scope off eBay and it's not bad overall. But the bdc is clocked a little off. It's not straight up at 12 o'clock. Is it possible for me to open it up and adjust the prism? It needs to be rotated clockwise, maybe a couple degrees. Looking for first hand experience so I don't dive in and break something

You are going to release the nitrogen fill at the very least.

I was under the impression that the knock off acogs did not have nitrogen or tritium. There was no mention of nitrogen in the description.

I guess it's not a worry then. If on the other hand it does, then you risk fogging.

If this is going on an actual firearm, I wouldn't expect it to hold zero or maintain functionality very well.

Why don't you consider a Primary Arms fixed magnification prism scope? Same concept as an ACOG and would actually be reliable.

https://www.primaryarms.com/primary-...cqb-m2-reticle

They make them from 1x through 5x I believe.

Knock-offs also support a pretty scummy industry in general. Don't buy fakes.

Probably filled with wuhan flu coughs from child laborers.

^^ This. My thought is to either get a legit ACOG, or if that's too pricey, get something like a Vortex or Primary Arms prism scope. I really want an ACOG, but I didn't want to spend ACOG money for the real deal. I would, however, spend $300ish, and for that I got the Primary Arms Prism 3X, and for that I got a prism scope with pretty good glass that at least has an adjustable diopter, which to my knowledge the ACOG does not.

There is a great article talking about the torture test of the PA scope:

https://www.tactical-life.com/gear/p...t-prism-scope/

This guy literally destroyed the scope, but he wanted to see just what it would take to do it. That scope will withstand just about everything but a direct hit from a rifle - certainly anything reasonable.

I hear the input, I know there are many way better scopes out there. Believe me, I know. But I'm just looking for some hands on technical acog info if anybody has it.

You do not have an ACOG, therefore, ACOG help will do you no good. No one in their right mind would crack open an ACOG at home. They would send it in for repair.

I would not try to take it apart. Shoot it till it fails and then move forward. Opening it up likely will not end well.
