Chasing the perfect Hi-Capa trigger break – my little experiment with the Begadi Pit Viper

Part 1:
I’ve always been a sucker for a really crisp trigger. Minimal take up, a well defined wall and a clean break with as little creep as possible.
I recently got myself a Begadi Army Armament Pit Viper and while I’m pretty impressed with the gun overall, I wasn’t entirely happy with the trigger.
The hammer hook measured about 1.5 mm in depth, which seemed excessive to me. The trigger wasn’t terrible by airsoft standards, but there was definitely some noticeable creep before the hammer dropped.
So I started playing around with the hammer and sear geometry to see what I could improve.
Rather than shortening the hooks or messing with the actual engagement surfaces, I decided to try something different. I cut two tiny strips of brass and glued them onto the hammer just below the hook, essentially acting as a stop for the sear.
This reduced the effective engagement from roughly 1.5 mm to 1.0 mm without changing the geometry of the contact surfaces themselves.
And honestly, the difference is pretty remarkable.
The creep is virtually gone. There’s a nice, defined wall and the trigger breaks incredibly cleanly now. It’s actually pretty close to what I was hoping to achieve.
I find it fascinating how such a tiny change in geometry can make such a noticeable difference in trigger feel.
Obviously, this is still experimental. I have no idea how well the glued brass pieces will hold up over time, and I still need to make sure the reduced engagement doesn’t cause any reliability issues or hammer follow.
The last picture shows the modification under magnification.
I’m curious if anyone here has experimented with Hi Capa hammer and sear geometry. I’d love to hear about your experiences, especially if you’ve managed to get a genuinely crisp, almost match grade trigger out of one of these things.

Akriva type 56-1

Simply changed to rs furniture and did a light weathering job. By far the most realistic airsoft gun I've ever picked up.

Does anyone know how I can get this?

Does anyone know of a way to get the Wii tech hardened steel hammer? I tried Wii tech but it seems they don’t ship here to the US

Not going for any super specific look. It’s fun to play with and looks cool to me which is what matters. Feel free to ask about any of the attachments or parts!

VFC mp7 tapp adapter short stroke / misfeeds

Hey my fellow silly war nerds. Picked up a VFC mp7 and got a tapp adapter as I will be playing in colder temps. Ran it this weekend and had mixed results. Set the npas to allow for about 1.3 - 1.4 joules and what seemed like enough kick for the bolt to operate fine. Most shots were good to go. But occasionally and sometimes many shots in a row would not feed or be significantly weaker with a weaker blowback sound. I observed that the bolt only retracted about a half inch when misfeeding, the nozzle didn’t leave the hopup resulting in not new bb in the chamber. From what I’ve researched and can feel, the nozzle return spring is quite weak. Anyone have a similar issue, if it is the return spring where can I pick up a strong one that’s in stock? The gun is properly lubed and would always fire, just sometimes not with a bb or with a lower audible and physical blowback.

Thanks for the help (video shows no issues, just normal operation on dry fire )
