Anti Drag Hammer
One of the biggest design flaws in the AF rifle is hammer chatter.
Everytime the rifle is fired, the hammer is released under the load of the hammer spring, by the hammer release.
The hammer release, under spring pressure stays in contact with the hammer through it’s travel creating drag and chatter.
The hammer is constantly rotating in the cocking/firing sequence.
This makes up for inconsistent hammer strikes.
Here is a stock AF hammer. Notice the chatter marks from the hammer release dragging along the hammer’s surface.
Here is a new hammer that I am experimenting with, the hammer cannot rotate and chatter is greatly reduced. The hammer release has minimum contact with the hammer.
This hammer also smooths overall feel of the action and seems to improve locktime.
Still experimenting, will post some velocity strings soon.
Thanks, Tony

You got it James…the hammer release will ride in the groove keeping the hammer from rotating.
Of coarse there are many other ways of doing this. I am trying to keep the hammer weight there without going too long in hammer length.
Rabbits, that is a 70 gram hammer that I like to use with the standard tanks.
The Condors need a little more weight.
I was wondering how it keeps from rotating also? maybe it really only rotates when you take the hammer in and out? Maybe the sear riding in the groove keeps it from rotating like you said?
Did you polish the sear also?
Is there enough material to make the “waisted” portion a smaller diameter so the sear part can’t hit it at all?
Another possible solution my Dad is tryng is he made some Delrin inserts to take up the space on the inside of the hammer so it rides right on the mirror polished barrel. He did this to take out the hammer slop. He also polished the stock hammer steel part you see the chatter marks on as well as polishing the sear part that rides on it…he needs to do some testing but he said it has WAY smoother cocking and firing cycle.
Very Cool Anthony! looking forward to see if it fixes the chatter? definitely a source of inconsistancy.
Jim.
I hate those shiny fancy inside parts. They are so great, but you have to take the gun apart to show them off. 😛
Looks pretty good. One thing, it seems like if the hammer wants to spin, and you have that channel carved out in there, it’ll spin until it hits the edge of that groove, and just grind all the way down that. Am I looking at it the wrong way?
very nice mate .i take it that hammer s for a condor or is it for any off the gunpower range 😀

Great idea and some nice work Tony. Have you considered a waisted hammer like Jim spoke on? I know when i polished the inside of my frame where the hammer rides i gained 15fps from that alone. Not giant but says alot about the friction going on during the hammer release.
