You have a standard FSB? And want to keep it? Do you have carbine length gas with standard 7" handguards? If so 7" two-piece drop on rails should work but be careful that SIG truly is standard length and uses a standard delta ring and end cap mount.

If you want to replace the FSB there is more to deal with.

Pins or set screws? If pins, they must be driven out (watch out for tapered pins).

Pins. I pulled the stock handguards off and measured them they are 6 5/8'' long I've found 6 7/8'' 7'' and 7.2'' not 6 5/8''
