Gamo BSA ASI breech seal:
There are 3 sizes. The easiest way to determine which size is required is to measure the internal diameter of the seal and the breech opening, then note the location of the seal. Is it in the cylinder body or the barrel? The lists below are not comprehensive or complete. We recommend using the method above. These are not Gamo factory seals, which are of poor quality like all the other sellers are selling. High-quality NBR CNC-machined, engineered to last.
