This is an improved hopup arm design optimized for SSX23 (it also works just fine on TM MK23) when using TDC hopup system. It's made out of solid CNC machined aluminum and is known to increase consistency of the SSX23 hopup chamber due to having no flex and larger concave contact area.

The design is based on the well known H-Arm by Hadron Designs and improves in several key areas:

it's made for a tighter fit for clone (non-TM) hopup chamber so it's always perfectly aligned and centered
nub contact surface to bucking has increased by 33% to allow bucking to apply hop more evenly
nub height has been increased by 50% to make sure that only the nub touches the bucking and the plate doesn't start deforming the rest of the bucking near nozzle
nub is better aligned to the SSX23 / MK23 barrel hopup window
start of the nub is rounded to gradually apply pressure to improve hop consistency

Compatibility

This CNC Hop arm will fully work with all these models:

SSX23 and SSX23 v2020
SSX303 (requires Mini Thumbscrew or shortening of original thumbscrew)
Tokyo Marui MK23
All clone MK23's like ASG, STTi, etc.

CNC precision hop arm delivers exceptional accuracy and consistency improvements for airsoft pistols. Customers praised easy installation and "laser" performance with various buckings. One customer noted over-hopping issues with heavier BBs, though most report it as a must-have upgrade that outperforms competitors.

Top stuff

Fits great in stti mk23. Works flawlesly with flamingo bucking and modify barrel

Great addition.

Fits great on SSX23, using it with 4UAD bucking.

Fantastisch

Sehr leicht einzubauen und hält was es verspricht. Hopup wird gleichmäßig belastet und BB‘s lassen sich super einstellen

Excelent quality

Presition increase with this piece. Makes ssx23 shoots lasers!

yes but i had to tweak..

i bought 2 of these and paired it with the new kid on the block bucking from 4uad (bought from them soon as they released) great match but for one thing i found it push a little towards the front of the bucking causing the opening to deform a little when the hop is added, so i took a dremel to it and had about 1mm off the nub, now it works great and push in the right place to match the quantum bucking, i also found they needed a little filling around the edge to allow the nub to move nice up n down with the tdc it was a little too tight in my tm and my asg, but im sure not everyone tunes there pew i found they work as is but i like to tune to get things right .
i then used the trigger upgraded springs which works great in all 3 of my mk23 (tm&asg) no hassles fitting them, now i dont have to tweak my own hammer springs. good thing tridos made these as i did ask another airsoft spring maker to make some 4 years ago and he wasnt interested so i had to tune my own... now its just buy from tridos simple....

Made with precision, but...

Sits perfectly in ASG and TM, but totally over hop even without the hop screw - 0.4g BB flying after 30 - 40 meters to heaven. May be too low gas output. I went back to hadron H arm v2.

Wahnsinnig geil...Maple leaf kann da einpacken

Great performance…

…as well as accuracy and consistency with the Flamingo bucking 50 version in an SSX23 and the 60 version in an SSX303, both with the upgraded hop arm and mini thumb screw - highly recommended !

A must have

In my opinion, it is better than the hadron hop arm. If you must have only 1 upgrade on a budget, it should be this one.

Perfection.

You need this. Seriously. Just buy a couple of them just in case. I did.

The best upgrade for your SSX303

This is the best upgrade you can do for your SSX303. I can't think of a better way to enhancing your consistency. It is dead easy to install - plug an play style.

Just great.

Very useful to keep the gun shooting straight. Ver good design.

Upgrading my asg mk23

Easy to instal and it makes the mk23 shoot more consistent (like i wanted) and giving tighter groupings.definitely a great inexpensive upgrade

That's just the point

Bb's fly like they should, straight, long, hard, after instaling it under Novritsch TDC sec. generation. Instal mini thumbscrew and you will get mini rocket in your pocket.

Fixed a problem with the original parts

When I first received my gun the hop seem to be lower on one side than the other. With this install and the X range bucking the issue is solved in the BBs fly straight.

Just WOW!

When I received my SSX23 it was shooting the best baseball curves ever, I had to bend my stock arm to make it shoot straight. A friend placed an order here at tridos so I decided to give it a go along with the thumbscrew, and DAMN! My SSX23 shoots laser beams at almost the same distance as my SSG96 and SSG24. This arm is the only upgrade you need to make your SSX23 a beast of a gun! Keep up the good work Tridos!

Problem solved

If your SSX303 isnt shooting straight then you need this Hop arm and the Mini Thumbscrew. Best way to solve this Problem!
My SSX303 is now better then ever 🎯

Amazingly good!

Already had the Hadron H-arm (gen 1) in my SSX23 but gave this one go and I have to say this outperforms the Hadron by a mile. I barely have any pressure at all applied from the TDC (SSX23 original) and it hops 0.40 gr BBs with ease. Fits perfectly and the results are insane. My SSX23 carbine is an absolute beast now!

Hi, I have a recent SSX303, I have used this upgrade on an ssx23 without issues but I read there could be some issues with the hop up stabilizer that comes with the SSX303. Any updates on that?

TRIDOS.DESIGN

The CNC plate itself doesn't have any problems but it's the stock hopup adjustment screw that is slightly longer and designed for the original hop plate. In some cases it can cause overhop with this CNC plate even with hop screw almost screwed out. To fix this you could replace the thumbscrew with our small one or slightly sand off a bit of material from the stock screw - worst case you can buy a replacement from Novritsch on the cheap.

Hello, I am debating on getting this for my ssx303. I am going to get the hop up stabilizer from novritsch that will have a hole in the hop up wheel. Will I have to get the mini thumbscrew? https://us.novritsch.com/product/ssx-303-hop-up-stabilizer-kit/

Thanks

I think last time we checked the arm worked fine with the stock hopup so I'm not 100% sure.

How does this install into the TM Mk23?

TRIDOS.DESIGN

It replaces the original metal hop arm but this upgrade requires TDC to be installed on your gun, if you haven't got one already. It will not work with stock hopup adjustment system.
