I can't seem to find anything searching on this forum, and nothing that make sense on google.

If you can help, it would be greatly appreciated. Thanks

OH and also, where does a hop up nub go? I heard they help for improving range

For future refrence, use the edit button instead of a new post. The nub goes inside the hop-up unit. It has a little cut-out section to put it into.

Just google Airsoft AK47 take down guide. You should be able to find some pretty quickly. AK47's are pretty easy to take apart, though. You shouldn't have much trouble doing it.

Google is your friend. It was the third or fourth link on google. Scroll down on the page a bit, you'll find the hop up disassembly.

Thanks, I feel retarded for having not found that when I went through looking on some different search engines.
