Hi,
There are several places that offer a recoil reduction system. All vent gases in such a way to reduce "felt" recoil and to some degree muzzle jump. The fine tuning that the boss system from browning offers may not be part of their systems. Williams Gunsite in Michigan offers a system similar to what you are talking about for a few dollars more, so 125 doesn't seem bad. If you have a front site it will be moved in the process and relocated so if you want a change it might be a good time to do so as well.
