Cyma Metal Hop-Up Chamber for AK Replicas

Solid chamber, much better than the stock plastic one. However, it's better to buy a separate rubber as the one included in the set is of average quality.

Great chamber for a reasonable price, I recommend it

I bought it to replace the plastic chamber in my AKSU. The chamber sealed much better, the feeding issues disappeared. If someone has a plastic chamber in their Double Bell replica, they should replace it with this budget one from CYMA. The chamber comes complete with a hop-up rubber.

If you have a plastic hop-up, you should buy this chamber right away, better sealing and durability

As it's a CYMA, the chamber fits perfectly in the CYMA. :) Comes with a hop-up rubber in the set.

More solid than the stock and locks the barrel better, I recommend it!

Sealed and most importantly, it has a metal slider

Saves the day
