STALKER MWS Kraken TDC Hop-Up Chamber for Tokyo Marui MWS

Video coming soon
Photos will be updated soon

One-piece aluminum hop-up chamber featuring a high-quality stainless steel hop-up adjustment wheel, compatible with a Kraken dual-fin bucking, ensuring the bucking remains perfectly aligned inside the chamber.
The hop-up chamber can also use any other GBB bucking on the market. It includes a Stalker Dual-Fin U-Hop bucking and 4 aluminum nubs, allowing you to set up the hop-up for BBs ranging from 0.20 g to 0.48 g.

This hop-up set incorporates a stainless steel adjustment wheel with a click system, preventing the hop-up from shifting automatically due to MWS recoil.
The adjustment wheel is regulated using a HEX tool.


FIRST COMPATIBLE TDC KIT IN THE WORLD

With the Top Wheel Set, available separately for the STALKER MWS Kraken Hop-Up Kit, you can convert this chamber into a TDC chamber, allowing hop-up adjustment via a removable wheel located on the top of the MWS receiver.

Note: the TDC Top Wheel kit is not included and is sold separately.

  • 1x Stalker Kraken Aluminum Hop-Up Chamber (one-piece)

  • 1x Kraken 60 Shore Dual Fin U-Hop Bucking

  • 1x Aluminum Recoil Stopper

Compatibility

Quick to arrive, quick to disappoint
Color: Black
Where do I start. Well. The only thing going for this divider was the fast shipping and affordability. But please be careful with the latter. This is exactly the type of product that teaches you that you get what you pay for. The assembly was ridiculous and lacking a lot of information and the tolerances to several of the pole pieces were incorrect. It is also very flimsy when assembled and I do not recommend buying this unless you absolutely need an urgent room divider. Best to save your money and get something sturdier.

Easy to assemble
Color: Grey, Color: Grey
Staying in a flex bedroom for few nights and got it to get some more coverage, super fast and easy to assemble, no tools or muscles needed, just pay attention to the ends of the bars : 2 vertical bottoms were marked, 4 horizontal ends are different to be easily attached to vertical frame; very lightweight but sturdy, nice shade of gray, the room still feels bright snd spacious; matches the description
