can you jug choke a single shot barrel that is modify choke?

I have a H&R single shot 12 gauge with mod choke that I really wish was full, is it possible to get the barrel jug choked or any other way to gain full choke?

You can send the barrel to Sumtoy and he can most likely do whatever you want. A lot of members on here have sent him barrels off their single shots to have chokes installed.
