thanks for the break down

You're welcome komrad.

First of all, thank you Comrade alakdan for this excellent tutorial.

I will be disassembling my AK74U next month, upgrading some parts and adding a Madbull tight barrel, and this is where I would like to ask a question...

Your breakdown goes as far as removing the inner barrel with the hop-up attached, but how difficult is it to detach barrel from the hop-up and then reattach a new one?

I'd appreciate any advise,

Milgeek

You should not have a problem removing the barrel out the Hop upunit and replacing it with a TB if you still struggel follow this below link it is the same as the RK02
hope this helps Gavin
Airsoft Barracks

Many thanks Gavin...

That looks fairly straight forward. I'll post up how I get on with this.

Cheers!

here is a tip when putting the gearbox back in a kalash RK0 aeg, put the gear box back tighten the lever screw , but do not put the grip on yet , I found it very difficult to put back the spacer that keeps the hopup unit against the gearbox and seal . by doing this you are able to alin the and fit the hopup against the gearbox and then you can put the grip back. hope you understand what i am getting to

Hooyah! up for this thread. very helpful. Thanks.
