WTB 12ga semi auto with interchangeable chokes for son

[RSK]

Looking for a duck/upland gun for my son's birthday. Started him off with my Rem 870 with a short stock and barrel but this year he asked for a semi-auto for his birthday Tried to go to look at the gun shops and just couldn't stand in line. Looking for a 28" barrel 3" chamber. Benelli, Berreta, Remington, etc.

Do have Spey and single hand gear that I could trade into the mix from some pretty nice makers.
Burkheimer, Tibor, Hardy Perfect Spey, GLoomis, etc. if that is something you are interested in.

If you have something you no longer use let me know what you have.
Looking for something local to Sac.

Thanks
Russell
