Things I liked: Excellent quality with regards to fit and finish. very easy to install.
Things I would have changed: It's just too tall. And obstructs the breech. I hate to give it such a low rating ,but it could use some refinement.
What others should know: I had to return it. The mounting position is way too tall . My neck isn't that long and i'm 5'9".
Things I liked: Love this product.Been using it on all my multi-pumps for many years. Literally the "life Blood" of your Air gun.
Things I would have changed: A larger bottle would be a welcomed addition .
What others should know: Use it as recommended and your pumpers will give you many years of good service.
