Verified Purchase

Things I liked: Seems to be a much better seal than the factory o.e.m. although I have not installed as of yet. The original seal has a pit that I discovered when tuning the rifle. When the seal totally fails, I plan to replace. Still averaging 914 fps on the chronograph shooting 7.4 grain pellet so not there yet.

Things I would have changed: Should be a better shipping method as the shipping nearly 3/4 cost of the product. USPS should be much cheaper I would think.

Things I liked: I bought this piston seal for my GAMO WHISPER FUSION,.177,Very good quality,you can use this seal in some crosman air rifle ,like my crosman nitro venom dusk.22,is the same piston seal.but is better than the original crosman piston seal.I think that PA should use USPS for shipping just smaller things like this piston seal.

Things I would have changed: NADA

Things I liked: Softer than factory seal, available from Pyramyd Air

Things I would have changed: does the job as stated!

What others should know: This seal fit my Gamo Whisper Fusion IGT perfectly! Looks like my seal was damaged at the factory, had a split in the side which dropped the power down, haven't been able to crony it since the tune because its been raining here, I'll post up the numbers as soon as I'm able.

  • Johnny from USA asked:

    Hello. Will this item fit the Gamo Silent Cat 1250 fps, .177 cal pellet rifle? I ask this question because I am not sure if the Gamo Silent Cat falls under the Gamo Whisper category which the listing shows that this item fits. Thanks.

    • Alex from USA asked:

      How good would this fit a AA TX200?

    • bret from USA asked:
