Allen head size

What is the Allen Wrench size for the Breech screw (that little one)inside the breech on a 1322??             Thanks Jeff

Jeff,
It is fifty thousandths of an inch (.050").
It is the smallest one in some sets and many sets don't even have it cause they only go down to 1/16".
Cheers

Fortunately, the steel breech kit comes with one.

Allen keys, Allen key sets - A MUST..!!

Not just for airguns. Everywhere you go, you seem to need Allen keys. About as common as screwdrivers nowadays...
