Things I liked: Everything ! This will fit into many of my guns for that wonderful NP feel
Things I would have changed: Maybe the part number to be stamped or etched into part , the ink one wears off in seconds .
What others should know: If you havnt tryed NP or other gas piston guns you should give it a shot ! I'll only use my old spring guns , anything new better be NP
Things I liked: This nitro piston has my Titan .22 shooting the way I had hoped it would when I bought it. Whether the original piston was defective from the beginning or whether the Titan came with a weaker piston, this new one is considerably more powerful. It also appears to be consistent, which is critical to accuracy.
Things I would have changed: Nothing.
What others should know: I have read other post that decry the price of this replacement nitro piston. I agree it is not cheap, but this is something one must consider from the beginning. For my Titan, I am now working to determine what pellet will work best. So far it appears Benjamin .22 hollow points are a good choice; perhaps they will be the best choice.
Things I liked: looks of good quality
Things I would have changed: I would give the mechanical properties in mm: body D/L:19./150 ...ram D/L :10.\ 110 ......Length of stroke ??105......Total length 263.....Initial strength ??? pounds
What others should know: The price is too high @ $50....should be $30/35 at the most
Can I use this to mod crosman tr77 nps
If your TR77 is an NPS then it should already have this same spring in it. I see you're from Canada, in that case I assume you want to bump power, if so you no doubt have a long piston which needs to be either cut down to 150mm OAL or buy the 15mm piston which in is ~$36CA. Check the airgunforum.ca for info. It is possible your gun also has a weaker spring, but the piston length is more important. Once apart you can see what parts you have. This springs # starts with BT9, the lower strength one starts BT5, which is inked on the spring.
Can I use this to convert a Benjamin B5M22PX to nitro? If so, do I need any other items and what velocities should I expect?
You likely have the same deal as the post above, so no doubt a long piston, and maybe the weaker spring. It's also possible the piston has a hole in it, which I forgot to mention above. So you really need to open it up to see what parts it has, then decide how to deal with it. Once all the power limiting parts are fixed you should break 750fps with 14.3gr pellets, even as high as 800 is possible but rare.
It worsk in a Crosman Fury NP 4.5?
It should be the exact same spring you gun came with. You can check with Crosman using your actual model # to confirm, or take your gun apart and check the # on the spring.
