"It's a transfer port Jim but not as we know it"
My take on a good transfer port is one that gets the air through it as fast as possible.
So has anybody tried a transfer port with a taper, not with the taper decreasing from the comp tube to the breech
which will restrict the flow of air but opening out to aid the air flow?

My experience is that it would be better without that massive chamfer , replace it with a small polished radius.

Always looking for any cheap, interesting, knackered "project" guns. Thanks, JB.
I have tried a few things the most complex was a take on the convergent divergent nozzle they use in gas turbine engines, I couldn't feel any change over standard, and it didn.t make any more power.
Is that what all the smoke was ?
What happened to the zero transfer port? Nick, we're you not tinkering with that a few months back.. I know bigtoe had a toe in..can't remember who else there was... Anyway.. what was the conclusion?

I recently reamed out a black transfer port on a Steyr leaving the exit hole untouched ,it made no difference to power what so ever.
Set rifle up with standard black port then swapped it for the reamed and polished one, nothing
I have often wondered if a 77 comp tube would take a Steyr port ?
