I do not like the breech tool provided with my new Black Diamond. What is the best alternative. I did not have the foresight to use a quick removal scope mount, which compounds the problem. What do you use??

I use the breech wrench they sell for the black diamond. After removing the striker assembly, you put this wrench in through the breech end. Its essentially a long tube that fits over the 209 adapter like a socket wrench, and a bolt that goes thru the rear of the tube that you use for leverage. When the bolt rotates around to where it is close to the scope, you just slide it and torque from the opposite end. When you have removed the adapter, the same tool fits on the breech plug. It works well. The only probs I have had is when I took too many shots with T7 and didn' t lube the breech plug good enough...
