    Umarex Komplete Hammer Spring Adjuster Mod

    I originally changed the hammer spring tension by putting a small slug between the hammer and spring. To change tension I would have to disassemble the gun, remove the hammer-spring assembly and try different thickness slugs. I decided to make an adjustable setup, and this is what I came up...

    Tuning General Operational and Math Question

    @AlanMcD Thank you for the detailed response. In the powder-burner pistol world, we call that a captive guide rod, not used for the same reason, obviously but the same principle involced in making them. Your explanations clear a lot of things up!

    Tuning General Operational and Math Question

    I made my own unit to use temporarily until the Inspire Precision unit gets here, hopefully by Friday. If you want to see some targets from a .22 Komplete, go here: https://www.gatewaytoairguns.org/GTA/index.php?topic=219436.20 They seem to shoot above their pay grade.

    Tuning General Operational and Math Question

    I'm running the complete with an air cartridge charged to 3000 psi; not the N2 cartridge. Also, being new to airguns, what exhaust port ( I plead ignorance)? I thought the barrel was the "exhaust port" after the pellet exited.

    Mine is the Umarex Komplete, and the other is the Diana Outlaw.

    Tuning General Operational and Math Question

    I am new to airguns; what is an SSG? Also the gun in question is the inexpensive, Komplete. It is regulated at 1800 psi, though I have no way to verify it. I am very happy with it and am just trying to learn different ways of tuning it for higher power. Right now I'm getting about 32 fpe...

    No, totally different manufacturers and different guns.

    Tuning General Operational and Math Question

    That's what has me puzzled. With the larger slug that I used in the hammer, I merely wasted air; the smaller slug kept about the same velocity, but I gained in number of shots. Does that mean that the plenum is too small and cannot provide enough air for the barrel length, basically emptying...

    Tuning General Operational and Math Question

    How does the barrel length affect the velocity. That is what has me confused. The example I sited has an 18" barrel doing ~85 fps more than my 23.6" barrel with about the same weight pellet. I did play with the hammer weight a little by adding a small slug under the hammer spring, which also...

    Tuning General Operational and Math Question

    I was just looking at different gun specs and came across a gun that has an 18" barrel, fill pressure of 3625 psi (regulator pressure not specified), and claims 985 fps and 35 fpe at the muzzle. I calculated that the pellet has to be 16 grains for this to happen. Now, my gun has a 23.6" barrel...

    Umarex Umarex Komplete; has anyone tried to disassemble one?

    If I am remembering this properly, I was getting 29 fpe with a 25.4 gn pellet at 720 fps muzzle velocity. I would like to push the velocity up a little for perhaps a little more range and effective kill energy. Looking forward to some pictures!!

    Thinking about purchasing this oil water separator....is it a good option? is there a better value i should consider?

    Mine isn't as elaborate but is a tuxing: https://www.amazon.com/dp/B0CT8MGGKC?ref=ppx_yo2ov_dt_b_fed_asin_title . Mine is a small Nuoge compressor (sold by many names, I'm told), and I added a pre-filter. Here is a picture of what I did. Mind you that I am only filling a 100 cc cartridge to...

    N/A Which of your airguns would you choose for a 60yd target for only one shot?

    What's the gun and model? Thank you.

    N/A Which of your airguns would you choose for a 60yd target for only one shot?

    @TitanRebel I would set up a bench at about 30 yds and throw a handful of mothballs under the shed. You won't have to wait very long for the skunk to leave. When the critter leaves, you could use just about any rifle at that distance to end his career.

    Umarex Umarex Komplete; has anyone tried to disassemble one?

    Curious if anyone has disassembled a Komplete? Are there any adjustments on the regulator? The only stated adjustment is the trigger pretravel. Any way to change the hammer spring? Just wondering if anyone has ventured into it; I may get curious enough to try.

    Filtering the Input vs. the Output of the Compressor!

    I have put a lot of this information into a .doc file including some from the thread that @Jfk742 linked to, but the file is too big to download. I like to keep good info where I can get my hands on it easily. Who said what and the links to the threads are in the .doc file. It's not...
