    I didn’t see any increase in fps with this new valve—596 fps with 20 pumps. I could get 718 fps from the OEM valve with twenty pumps; although, 20 pumps was hard on the seals. I might try substituting back in the original hammer spring and/or valve port but, so far, not impressed with this ‘upgrade.’ However, it was easy to install. Not sure why I need the included frame screw.

    Solid buy

    Good product. As advertised. Put mine on a 1322 with a 14" barrel and a Buck Rail suppressor. The combo works well. Haven't had a chance to chrony the pellets yet but the power increase is significantly noticeable and improved the accuracy of my 1322 carbine. The suggestion to stay between 15 and 20 pumps is pretty reliable. If you are trying to get more power out of your 13xx this definitely works well. I definitely recommend you upgrade your barrel length to make use of the extra power and put a suppressor/moderator on the barrel because that extra power makes an even bigger bark than stock. Thumbs up on this product.
