Why is it such an issue to have the actual physical dimensions (length and diameter) taken for this item and posted in inches with the product discription? There are literally dozens of older model air rifles that these pistons could fit.
OD is .96 inches, ID is .78 inches, and Length is 5.62 inches
What is the diameter and length of the metal piston?
OD is 24.4mm, ID is 18.75mm, and the Length is 142.78mm
Will this piston fit and work in a 1982 UMA/MILBRO Model 61 .177?
Most likely it will not fit. This item fits RWS Diana 25 and 25DS air rifles.
