Others MK II .177 Reseal Success

[Hylander]

Second time redoing an Airgun.
This is my MK II .177
Received the reseal kit from Henry Ford today.
Excellent guy to do business with.
Already had the pistol apart and ready.
Found a writeup on Pyramyd that was very helpful. Anyways, no leaks, function & fires great.
Now I have a nice MK II .22 and .177

I did the same thing with a number of pistols...I love the Mark I and Mark II pistols. I got my parts from Mike Baker. I only use urethane seals.

The older versions with the hammer spring adjustment screw, I like the best. I "tuned" a Mark II to shoot H&N Plinking pellets (the cheapest pellets I can find) to shoot very well in a Mark II. I did one test where I turned that screw in 1/8 turn increments and watched the groups tighten up, widen again, and then tighten up again at a higher velocity. So cool. Just be careful because that screw is really soft metal and the slot can easily can bent out of shape. I worked on the sides of that screw while I had the gun apart and got it moving with pliers before I used a screwdriver on the slot.
