Have A .25 regulated Flex in for a tune!

Customer complain of poor shot count and accuracy. 

here are my findings:

1. The hammer spring is way to strong for a reg that is set at 130b. I think this spring is used on non reg .30 and up

here is the new shorter spring to give the hammer a free floating effect like all FX hammer, the results are 64 shots with 12FPS ES from 220b to 130 fill shooting kings at 900fps and vary quiet. before tune she was getting around 30 shots with high ES and sounded like 3 cannon going off in a row.



2. the bottle threaded adapter to main reg chamber air tube is unable to fully thread and bottom out. the results is a bottle that can flex up or down while pressurize and touch the shroud, I place a shim so that all 3 parts can be tightened down and centered.to give proper clearance with the shroud and bottle.

more review later.

Ernest,
My Flex did need some adjustment of the HS when I got it. Travis sent me one of the shorter springs, but I was able to get it tuned with just the pre-load adjuster. According to my gauges I have my reg set at approx, 2050lbs. When filling the bottle to 3600psi I can get 72 shots at 808fps (King Heavies) with a ES of 10fps.

Maybe I can do even better if the shorter spring is able to work. The one he sent with my gun is approx 3" long with a wire diameter of approx .064". Is that the size of the one you used? Is it able to "free float" when un-cocked? Thus reducing hammer bounce? Mine is much quieter once I adjusted it, but if I could eliminate the hammer bounce by allowing the hammer and spring to free float when relaxed that should even better the efficiency.

Is the gun you got an "older" one with the JDS Airman regulator? Or one of the newer ones with the Regulator Travis had put together? If the reg is one of the JDS Airman ones you can make the gun perform a LOT better. Take the piston in that reg and throw it out, it's JUNK. Replace it with one of the Ninja pistons and the reg recovery will be 100 times better and it will no longer have the creep that the JDS reg has. I shared some information with Travis about the reg's and since my gun he is no longer using the OVERPRICED JDS Airman regs.

Not sure what you mean about the reg bottoming out, and not fully threading. My reg to block is perfect, there is no "adapter. I have the bottle, the reg and the block. No play in it and my bottle is a good 1/8" away from the shroud so no touching there at all.

One additional thing you may want to check on the .25 is the magazine. With mine the King Hvy's were too big diameter. I used a sanding wheel and enlarged the inner diameter of the magazine case. Now the mag rotates freely with pellets in it. Prior to doing this the pellets would "rub" on the inner wall as it rotated. I think this was slightly deforming my pellets. All fixed now. I routinely get nickel sized groups off a sand bag at 50yds.

BTB thanks for the inputs"


Yes, the hammer is free floating about 3/8"----its 3" OAL wire size .062, with this spring I can go up to 950fps with 25g

yes the reg has a creep and must be the older one, it will shoot about 8 fps faster when it stop creeping--I say around 10b.

on the photo is the threaded block labeled in red. when this block is bottom tight it will force the shroud so high that you cant screw the breech/barrel on.so you have to back it off till the flat side of the block is squre with shroud--now you got a wobbly bottle.

Ernest,
Now I see what you are talking about. My block/tube (as far as I know) is fully seated, and does not interfere with the shroud at all. In fact like I mentioned the bottle is 1/8" away from shroud and the block itself is about 1/16" below the shroud. Maybe the threads were cut just a tad father on the one you have.

If I have read correctly "all" of the Flex rifles are designed with the hammer spring "free floating". I remember Travis saying that in an uncocked state there is like 1/2" free play. I never removed me hammer spring, but he was saying that the spring rides on 2 "guide" rods allowing the gap and also to stop and twisting of the spring when cocking.

Anyway here is a link to the post I did when I got my gun and "fixed" the regulator.

Here is the difference in the sealing part of the Ninja Piston (on right) vs the JDS Airman Junk. Overnight mne would sometimes climb 200psi (14bar)



For about $12 you can do wonders for the reg's performance.
