Faux Acog

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 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

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-arms-slx-3x32mm-gen-iii-prism-scope-with-acss-556-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.

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.

^^ 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/primary-arms-compact-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 bought a cheap ass monstrum prism scope a few years ago. It’s not a acog clone but it looks like it uses the same technology. I was using it and I noticed the image moved around when it was on a rifle and I was dry firing it. I ended up getting it replaced under warranty and the didn’t want the old one back. I took it apart and the adhesive cementing the prisms to the prism block had let go over one of the prisms. I ended up using epoxy to hold the prisms back in place. In taking everything apart in noticed I had managed to mess up the orientation of the reticle. The reticle was in a holder in front of the prism block. It is really easy to adjust on this scope. There are two holes to rotate the reticle. I ended up staking the reticle ring with epoxy.

I wouldn’t be surprised if the way to adjust it exactly the same as this scope. To adjust only the reticle you’d have to remove the four Allen screws. There was a sealant holding the rear of the housing to the rest of the scope. Once it breaks free you can see the inside of the scope. The prism block is right there. The two holes will allow you to rotate the reticle in the holder. I’ll find a picture
