How To Choose The Best Red Dot For Kel Tec Sub 2000

Kel Tec Sub 2000 is an amazing gun. No denying that. But finding a good red dot for the gun is quite hard. After all, there are so many options to choose from. On top of that, a lot of red dots aren’t even compatible with the gun. So, here is my take on how you should approach the decision.

Build Quality

Make sure to take an optic that is built to last. There are cheap optics available on the market that are built like papers. Don’t fall for those honey traps. Make sure to take a red dot made out of metal. No plastic is allowed.


Kel Tec isn’t a heavy weapon. It’s quite light. To add in an optic on it is to add in weight. You don’t want to go overboard with that. Take an optic that is relatively lightweight and durable at the same time. Lighter weight allows you to explore magnifiers or NVD down the line as well.

Lens Quality

Lenses are the life of an optic. They are your second set of eyes. If they are not good, then you will have a very hard time using the optic. So, make sure to never skimp out on the lenses. Fully multi-coating glass lenses make a huge difference. Bigger than you think.


The biggest concern while buying an optic is always the budget. If the budget is too tight, you are then limited to choices. And when you have a high-budget, you have countless options. So, make sure to fix a budget in your mind. It will make your decision making easier.


Well, there you have it. The list you have been looking for. The best red dot for Kel Tec Sub 2000 with a little bit of heads up about how to switch it. It’s not an easy task, I know. But the task will majorly depend on you and what you want from your optics.

After all, I’m just a mere messenger who can show you the path. But you have to walk on that path yourself. If you can just identify one or two options from the list that suits your needs, then you can easily make the right decision.

With that said, that’s all for now. I will be back with more helpful guides in future. Till then, take care and stay out of trouble.
