FX Wildcat MK1 .22 Hammer Springer Adjuster Mod

[Paio]

It was not holding on the position even with thread lockers. I increased thread length (added 5mm in my case) to be flush with the block with initial velocity around 780fps. Had a groove made and inserted an o'ring to act as a locknut. It is working well. JSB 18.13 optimal velocity after adjustment is 860fps.

WOW, that is great work. I need one for my MKII. I've tried all but red thread lock and they all come loose with shooting.

Clever!

Nice you may want to market that I think you could make a killing. I’ll take 1 for my streamline.

My thoughts exactly. I've seen a few different ways of keeping it in place but this way is definitely a winner. Put me down for one if it works with my MKII. This is something that FX should have done a long time ago.

Shouldn’t it only be the nut? Won’t that interfere with the hammer weight?

Since I am not in the USA it makes a bit harder to help my fellow airgunners. Also, I have no access to other airguns other than mines. Hopefully the pictures I am sharing can help the community when sourcing from a local machinist. The issue with this adjuster was the spec M16 X1 which is not easy to find the proper tools. We had to make a nut in a lathe to use it later to calibrate the thread's adjuster.

I didn't understand the question. However, this mod does not interfere with the hammer in anyway.

Must be how the 12 ft lbs ones are set up. No hammer weight.

Your right about the thread size being oddball. So guys have modded this to make stops....

Ahhhhh. Gotcha. I just know that won’t work in mine. Ok. I get it.
