Below are the chronograph results for 7.4 gr pellets for the last few days.
The first 2 shots are high and then the muzzle velocity drops a lot.

Piston seal or breech seal needs help or replacement.

Try feeding the piston seal a bit of silicone oil. If that doesn't do it your spring could be broken but it sounds more like a dry piston seal.

Earl, I have a cleaning kit that is marked "B2" and it contains a leather piston seal that "looks" very much like the one in the Tech Force 6 video. I don't have a B2 so don't really have any use for the piston seal. If you can confirm that a B2 piston seal (leather) will fit the TF 6 I may be able to mail it to you?
Kit looks similar to this one but piston and breech seals are leather, it contains a main-spring, and here is no trigger sear.

I think I got it from Pyramyd Air but can no longer find the kits on their sight.

lefteyeshot is sending me the seals and a spring.
He has 2 QB6 guns that are the same as my Tech Force 6 and he has taken them apart.
He is going to "walk me thru" installing them on the phone.
Thanks for all the help.
I will post the results.

I put the new seals in the Tech Force 6 today.
The gun shoots good and consistent now.
566 fps with 7.4 grain pellets.
446 fps with 10.3 grain pellets.
I am a happy old man.
Thank you lefteyeshot for the new seals and spring !!!
