I zero for slugs at 50y. Except for short distance, if the dot is near the target, birdshot will hit. Hold slightly above target for close, just like you would with a rifle's mechanical offset.

Same here. Zero slugs @ 50 yards and birdshot is near perfect.

Its been years since I bought my MKA 1919 and the first thing I did was remove the plastic front sight tower, the carry handle and the factory chokes.  Tossed them in a box and never saw them again.  Replaced the chokes with Carlson extended chokes.

If they have notches, maybe they use the same "code" as Browning.

 I have Briley extended ported chokes from IC, LM, mod and a ported Carlson IM choke for long and tight shots when there are no shoot plates, spinners, BS, & heavy plates. The Carlson choke really holds a tight pattern. I have shot my slugs thru all of these with no change in POI. I use IC & LM the majority of shots. I have the mid barrel T & N comp. Not sure if the ported choke helps, but they look good.

What pattern choke tube does the MKA use?

Then what may I ask?

 

Have you barrel re-threaded for win chokes. Win-choke will screw in but its loose and sloppy until it bottoms out.

 

We had some of our breacher chokes threaded for the match 21mm pattern but if you plan on shooting a lot of 3-gun have it reamed and rethreaded.

Remington ProBore chokes are the opposite - more notches means tighter.
