Bump for a good gun and the modification that needs done on these has already been done. It took me a lot of years to figure out if you shorten the length of pull on the BPS mag 10 it makes them a dream to shoot.
The BPS is a fantastic shotgun, been hunting them my entire adult life. I have three in 10ga and have not shortened LOP on any of the nine BPS i own and all have run flawlessly. Why is this a "modification that NEEDS done"? In all my years i have never heard of BPS's needing shortened and personally that kills a sale for me.
