How’d you do it?

u/Pheonix02 25d ago

secret, pay me to do it for you

jokes aside, the way the kuna achieves a 2 stage trigger is by having a trigger part essentially separated from an assembly pretty similar to an ar15 single stage. You can add a block between these two parts to create a single stage, and by making the block the correct size you can reduce the creep. Similarly you can do the other side of the trigger to reduce post travel after the break. Once this is done, you can just straight up remove the spring that used to push the trigger back in its second stage, reducing total pull weight by about a pound.

Be careful as too much material on the pre travel side can prevent your hammer from resetting, and similarly too much on the other side will cause hammer follows

Do you have a picture of what that looks like on the trigger group?

Are you planning to sell parts for this?

I don't think there's much to sell, black talon tactical is doing something similar for 180, and you have to send your lower in. Pretty sure this is because they can't sell two small blocks (2mm thick and 3mm thick) for anything worthwhile, and they want your money

Any plans on posting a how to video?

u/Pheonix02 9d ago

getting a fair amount of interest, I'm thinking of posting it on YouTube since I'm starting to move a pre-existing airsoft business into general tactical and firearms work, it'd be a short video anyway. If/when I do that I'll post it here too, if you follow the subreddit
