Is this check valve pump piston uncommon ? Seems to be something that should be a standard mod..

Half hour drive would be easy. It would be fun shooting indoors with springer guys.Funny you brought that up. I have had about 12 to 15 inquiries from readers on this forum that are about a half to 2 hours away. Several said they were coming. Not one has ever shown up. That's disappointing on many levels . But as they say, It is what it is.There is a lot of shared knowledge at our matches but I guess they are not interested.
This is exciting to hear! I'm also a fan of the new chassis, I didn't mean to imply I wasn't. When you get around to introducing something to increase power and shot count it will definitely be worth revisiting. In my experience so far, I'd want to see between 905 and 955 fps with the 40 gr Kings, for around 18 shots. I know most people are looking for 12 shots... but I regularly shoot PRS matches with 15 to 18 round stages. Nationals this year actually had a 20 round stage. In an extreme situation like that you could get by with a few shots off the reg (probably). But less than 15 will be leaving points on the floor too often.but even higher velocity , or number of shots per fill can be increased and even retrospectively on already sold models, it is just not in our power to introduce everything at once. The new stock is also backwards compatible with older M24s.
That chart says Michigan has a restriction, but I live there and there i no restrictions other than for big game hunting it must be above .35 cal.
@thomasair Oh that’s a nice discount. Thanks for sharing that information.It's 35%
Sorry if I place this in the wrong category the admin can delete it
it shoots very good, and the scope is good actually wasn't expecting to see chp 14g go 830- 845 fpsI’ve had one for years. Quite a fine piece in my opinion. Once you get your hold down it is very accurate. Little bit heavy but well worth the effort.Hope it works well for you.![]()
Dang thanks so much for the summary. I'll work with that approach. I'd definitely gotten the reg out of whack. I did read the CW / CCW rule on the site I got the new block from, at the moment I'm still with the stock reg that requires degassing, taking the tank apart, reg pulled out & adjust. I had no idea about the 1/16 turn increment, I'd watched some mod videos and 1/8 turn increment was the suggestion but I did 1/4 because I hadn't learned the "less is more" concept with airguns at that point lol. Learning that one the hard way now. But knowing me, I'll probably still want to degas & reduce the reg a little more before then like was suggested by SB237, just for learning purposes. If 1/16 turn is all that it takes for any kind of change, very good chance it's too wide open due to my guessing where it was at prior to disassembly.
The hammer spring, how would you measure the PSI it's set at? I could locate a tool that measures spring tension somewhere if need be, unless there's a different method to find where that PSI is at currently?
Last question for now...before I took it all apart, it was zeroed right around the middle of the elv/wnd turret adjustments' extents...good bit of leeway for adjusting in either direction. Now, it takes the windage being cranked all the way to the right-end stop before it's centered L/R with where boresight is. I took the back rail back off & re-seated it with no luck. Something got off somehow & not sure what's causing it. As an aside, does the POI change with the angle down that you're shooting? I'd have the zero set just right when level with the target around 40yds, but then go up to the second floor from the window in the house....and with crosshairs at the bull, hits about an inch below. I can't see a powder bullet having that kind of discrepancy, unless pellets are something else? Same distance, same POA, higher shot angle, lower POI. I can't figure it out.
I'm learning a ton from everyone on here and once I"m through the beginner screw-ups I know I'll have a much easier time with the fine-tuning & mods...I just hope to build a good foundation of know-how on the basics before I move forward, I'd really like to stick with this hobby, despite its sometimes budget-unfriendly nature HA! Thank you again.
Thank you for the clarification FirewalkerUnlike the Zelos, the M60 also has an air stripper/adapter combo at the end of the barrel. The Zelos has a 3-3/8" empty space inside the shroud creating a chamber to help tame the report.
