yes, I have a 311a double barrel 20ga and the left barrel is a full choke and the right barrel is modified. I also have a Springfield 511 double barrel and the chokes are the same on it. If you look at the end of the barrel you can tell one of them is slightly smaller and that is your full choke, that would be the left barrel and the right barrel is modified. I hope that helps. Of course, if they are improved and open there will also be a difference in the measurements. Just take it to a gunsmith and ask him to check. If he has the gauges, it will take him less than a minute and he probably won't even charge you for it.
Mic the ID of the muzzle compared to the ID of the unchoked bore. Most of these guns will be Full/Modified or Full/Full. sales@countrygunsmith.net
