Briley's are expensive, especially as their tubes are almost double the cost.
The gun is choked M/F, I could leave them alone, or open them up. But opening them seems to cost even more than tubes. I'm not worried about recouping the tube costs, was just wondering if the guns sale price would be less. Guess it depends on the buyer, I was looking for one that already had tubes
In terms of re-sale price, its likely to be a wash.
The purists among us will be scandalized that the gun has been altered in any way, and either refuse to bid on it or offer only lowball bids. The shooters/hunters among us who understand the value of changeable choke tubes will eagerly bid and offer some premium over guns that dont have screw in choke tubes.
Ive had a number of my SxS Spanish guns that came with fixed chokes altered to screw in chokes. I use Briley if the barrels are so thin that thin wall chokes are needed (and have paid $450 for the installation and five, lead/bismuth, choke tubes). If the barrel walls are thick enough for regular choke tubes I have had the work done at Colonial Arms, (and have paid $155 for the installation, plus about $25 per choke tube).
Your gun, your call :-)
