This is a must have upgrade for every AAP-01 as it's only a matter of time when the stock hammer will fail. Our CNC machined stainless steel hammer is more affordable and just as strong.

We include a special assistance jig with every unit - this ensures an extremely simple assembly procedure that we believe anyone can do. Even our clumsiest test subjects managed to do it.

Includes the following parts:

  • Part 45 - AAP-01 Firing Pin Lock (Stainless Steel)
  • Part 52 - AAP-01 Hammer (Stainless Steel)

Compatibility

✔ Compatible with AAP-01
✔ Compatible with AAP-01C

Should be compatible with most upgrades on the market but we can't guarantee 100% compatibility with every after market part.

Stainless steel replacement hammer highly praised for durability and easy installation. Customers said the included jig is "AMAZING" and makes replacement "a piece of cake." Installation videos and affordable pricing noted as major strengths. One customer reported compatibility issues with semi-auto mode, though most found it robust.

New Hammer for my AAP 01

Looks just like the original part but will last longer as it is made from stainless steel and not some mystery metal, the instalation jig makes it easier to fit and less to take apart, great job guys keep up the good work

Kickass!

This hammer kit is very nice, it’s nice to see a company besides cowcow making a replacement kit, and it just comes with the two parts that really matter in the kit, so you can save on costs. The tool they give you helps a ton too, I actually reused it to do a couple other friends guns for them. Really nice instruction video on their channel too. 10/10

Perfect installation and seems robust for the price!!!

Bought this as my old hammer from the AAP 01 snapped after a year and a half of use. The whole set up and installation was super easy as it was my first time going through this. Well done for coming up with this product and fingers crossed this set will last a while 🙏

Absolutely amazing!!!

My AAP-01 never worked 100% but after the hammer broke I thought I was done with it but this paired with the tdc hop made it feel like a whole different gun highly recommend and very easy install

Good design but qc

Install is easy but wouldn’t work in semi white the original Auto sear

Hi Julian! Sorry to hear that you're having some issue with it. We have around 7 different AAP-01's in the office and we've tested our hammers on each one of them and haven't been able to replicate this issue. That said, due to manufacturing tolerances, each pistol can be slightly different and it's possible that it could result in such malfuction. We're more than happy to provide a full refund in this case - let us know if you'd like to go that route!

With the provided tool and following the how to video on Tridos, I was able to get my AAP-01 working again. Cheers

Will this work on Marui spec G series hammer systems as well?

TRIDOS.DESIGN

Unfortunately, we haven't been able to test this yet. I believe some of the other sets sold for AAP-01 are compatible with Marui G series hammer units so it is possible it will work but we can't guarantee it.

Is the fire lock pin. Also steel/ss?

TRIDOS.DESIGN

Yes, it's also made from the same material as the hammer.

I think I will buy this product as my hammer broke and heard that the cowcow hammer damages the bolt on the aap01 but what makes this hammer way cheaper than the one that cowcow and action army sells?

TRIDOS.DESIGN

Unlike CowCow, we only include the hammer and fire pin lock which are the two main parts that are prone to failure. Material wise, our parts are just as strong. And unlike Action Army / CowCow, we don't charge 10x for the part just because we can. Paying 50-60€ for a hammer set is outragous in our opinion and in this case there is no reason they should be that expensive.
