I just bought a Stevens 311 20 gauge and I can't figure out what the chokes are. It's an older 311 chambered for 2 3/4" shells and the barrels are 26". The only makings on the barrels are "SX A J".
The A and J have a circle around them. Any information would be appreciated!

  DO YOU HAVE A MEASURE. I WOULD THINK THE CHOKES WOULD BE MOD AND I/C. ONLY WAY TO TELL IS TO MEASURE.
  
  I WOULD RATHER BE DUCK HUNTING.

  As Duckhunter said,a 311 20 ga. with 26" barrels should be choked imp. cyl. in thr right barrel (front trigger)and Mod. in the left barrel (rear trigger).The only way to be positive is to use a choke guage. www.brownells.com has them.Not expensive.

  Save your money on a choke gage. A 20 gauge has a .615 Bore size
  Improved cylinder has a .010 restiction or would check around .605
  Modified has a .015 restriction or would check around .600
  Full has a .035 restiction and would check around .580
  get yourself some calipers and check it up. If you do not have any, visit any gunsmith and they will check it for you.
