Home tune on LGU?

[Vernal]

It is shooting well, so I'll leave it and run it in some more in time for the bash

Very good thinking. While you are there, you might like to try my Nick G tuned LGU -very quick, no recoil, and pellet on pellet.

Hi Sunbeam,

I have the LGV (the break barrel version). I find it very smooth and accurate but note like you that it has some recoil. Some of this is or rather seems to be twist (torque from the spring?). Now it is out of warranty I intend to strip it polish the spring ends and remind to see if that helps.

I am also thinking of adding weight at the muzzle to see if that reduces any muzzle flip. This latter option is a cheap, easy and reversible way to see what happens which might be worth trying on your LGU?
Cheers Rich.

Pure physics dictates that you will always have recoil in a spring (or gas) piston powerplant. However, this can be reduced in many ways, by tweaking the internals and/or increasing weight and altering the weight distribution to give more favourable movement characteristics.

I've mentioned a few times on here of one particular LGV that starkly demonstrated the twist you mention. I also opined at the time that I believe this phenomenon to be more illustrated in guns with rotating pistons. In all fairness, that rifle shot beautifully. Very little perceived recoil and a very quiet action. Shooting at a 20 yards indoor club range with a high mag scope and the twisting effect was very prominent. Certainly not knocking it as it was accurate and forgiving to shoot. Making sure those spring ends are square and true, polished and with the addition of some polished steel washers, or Delrin items, will hopefully reduce this.

I have some nicely tuned guns,but I have tried Vernal's Lgu at the last Bash and it is the mildest fireing springer I have shot yet..

Just as an update on behalf of Sunbeam, he ended up getting a TX and sold the LGU, I seem to remember.

And yes, sir, your LGU has a most dignified demeanour.
