    Level 10 Springs - Gold Starts ~200 fps, Red Starts ~330 fps

    I've got an X-Valve with Level 10 and a Classic Valve with Level 10. Both Level 10s are newer production, purchased new this year - X-Valve from Tuna, Level 10 for Classic Valve from AGD.

    The gold springs in both valves start shooting around 200 fps. By the time I get them up to 280 fps, they're not quite as gentle on paint as I would like. However, the red springs in both valves don't start shooting reliably until about 330 fps, so I can't use them as they are.

    Is this normal nowadays? The four Level 10s I had in various markers in the mid- to late-2000s-ish would usually start shooting with the red spring around 250 fps. These older ones came with all the extra carriers and three springs - gold, red, gray.

    I'll try cutting a red spring later a 1/4 coil or so at a time, but I wanted to hear what others are experiencing.

    Both markers are otherwise healthy, to spec, and all AGD.

    Use a #0 carrier... and the red spring with a rung cut off

    I’ll give it a shot. That doesn’t give you bolt stick issues? I recall lots of bolt stick issues whenever I tried to run smaller than necessary carriers.

    I have #0 in literally ALL of my mags

    No dice. Tried 1, 0.5, and 0 carriers in both markers with two red springs cut 1/4 coil at a time to -1 and -1.5 coils. The issue remains.

    One other detail with the Classic with gold spring I noticed at the field on Saturday and confirmed today - the Classic limits out at about 265 fps. The slightest increase after that results in about 320 fps.

    So:
    1. I can’t run red springs in either marker, even when clipped up to -1.5 coils. This is about 1/2 coil longer than the gold spring.
    2. I can’t get to 280 fps with the Classic even with the gold spring - replaced reg seat, reg piston (anticipating a leak with the old one when switching to Level 10), and thoroughly cleaned and re-greased reg spring pack.

    That said, I don’t know the spring constants between the gold and red springs. If the red is higher, do I need to clip the red shorter than the gold?

    Again, I never had to clip the red springs 15-ish years ago. Have the specs changed?

    have you checked your regulator pistons?

    Replaced the Classic reg piston with a new one from AGD when I installed the Level 10. I tried the old one for comparison; it does the same thing.

    I have not replaced the X-Valve reg piston.

    In search of a Classic regulator spring pack assembly. The one in this marker appears to be an old design or non-AGD. It's got loosely packed disc washers and a large flange on one end. I'm guessing between the 265 fps and 320 fps points described above, it just becomes a solid metal mass - no "springiness" left. I've contacted Tuna and Jake. Any other individuals I should contact?

    For the X-Valve, I decided to just discard the existing o-rings, thoroughly clean everything, install new o-rings, oil the o-rings, and re-grease the regulator springs. Everything seemed to assemble/move much easier; i.e., not as tight of o-ring fits. It seems to now be shooting "mostly" reliably around 275 fps, and fully reliably in the 290-300 fps range, so that's more in line with what I'm used to.

    For closure, I'll try to remember to post on the Classic with both gold and red springs after I install the new regulator spring pack assembly.

    Classic regulator spring pack assembly arrived today. Classic problems resolved. Gold spring starts shooting around 200 fps, the red spring starts shooting around 250 fps, and I can tune velocity from 200 to over 300 fps. It no longer jumps from 265-ish to 330-ish.

    For reference, here are the old and new Classic spring pack assemblies - old is left/bottom, new is right/top. Sorry for the poor picture orientations. Also, I should have flipped the new one 180 degrees in all of the pictures, so the common end between the two were oriented the same.





    As for the X-Valve, I believe the reason I can't get the red spring to start shooting at 250 fps is because I'm getting some pretty bad first shot drop off. If the velocity with the gold spring (using the simulated rapid fire technique) is set at 265-280 fps, my first shot (without using rapid fire technique) varies quite a between two "groups". Sometimes it's 240-255 fps. Other times it's 205-220 fps. I think the former would be acceptable given the recharge rate, dump chamber cooling, etc. However, the latter seems excessive.

    Apply these same spreads to the red spring, and I think it would explain why it won't start shooting around 250 fps. As previously posted, I've changed all o-rings, cleaned and lubed multiple times, and played with the torque on the field strip screw (wrench tight seems to be best).

    I'm going to try swapping on/offs when time permits to see if the problem follows the on/off or stays with the valve. Any other ideas?

    Thanks,
    Nathan
