I have the 20 ga br550 and I like them a lot. 29" barrels, teague chokes, steel capable. I changed out the wood recoil pad/extension and put on standard rubber. It brought the balance just a fraction back to just ahead of the hinge pin. I didn't want to change the screw hole placement in the buttstock in case I want to put the wood pad back on. The hole spacing is metric so you're limited on the pad choice. I used the Gazalan 1/2" solid recoil pad with a 3 1/4 hole spacing. That gave me a 14 11/16 LOP. The oveall fit of the stock is pretty close to the 20 ga. Parker Repro so with the exception of cast(I need a little more off) it fits pretty good. I also have the case frame, I like it better.
