The First up is the Benjamin 137 total rebuild with a new Airgunsmith Piston

I love this little Benjamin, don't let anyone tell you they cant be modified. here are the numbers,[image]

This is a moderately modified valve, I have no doubt the Benjamin can hit over
500fps but this little thing would most likely fall apart in short order.
