Has AF ever changed the barrel mounting position??
Just received a used barrel that has delrin bushings (didn’t know this when I purchased it but I didn’t specifically ask either).
I dropped the barrel in my TSS frame and snugged up the set screws as best I could. Then I opened the breech… barrel is sticking out an inch too far to the rear. I’m not worried about solving the problem, just curious.
Could be a fluke but i’m wondering if there was ever a design change that would explain this.

Normally with those delrin bushings the setscrew are snugged up against the barrel OD. The bushings are just slidefit. You can move the barrel forward as much as you like. I usually put it as far backward so that it still cocks.

Very interesting!!
Slug that barrel and see if it has a choke
now I feel better about my purchase… 😳
Old AF barrels with delrin bushing can SUCK ASS.
They changed to LW barrels
Delrin bushing often were held in with 1 set screw back in the day.
That’s good enough for me. This one would definitely conserve air. It’s back far enough to prevent cocking the gun at all….. 0 air used, 0 air wasted.
Next question. Are the delrin bushings simply snug to the barrel? I don’t recall seeing a set screw as with the AL bushings. I can imagine a scenario where the barrel was pressed into the gun (sliding in the bushings) if the right (yet still unhealthy) forces were applied.
I’m going to take it back out and make sure I didn’t flub it and make all this up.
Thats news to me.
I do know some guys would move their barrel back in an attempt to preserve air at the breech.

My .22 barrel had delrin bushings, no setscrew. The slid off with moderate pressure. Its a superb barrel but I made aluminum bushings for it.
I think the bushings were drilled after installed. The screw dimples were machined in.
