Im building a high speed ssg setup myself. It is based around the ultra high speed warhead.
So it was interesting for me to follow this thread. Thx for all info.
One thing that stood out by absense is air leak on bucking. It was mentioned but a really good fix was not there. There is the dental flos fix and the teflon tape fix. Both are a bit sketchy cos it doesnt last.
What I did to fix leak from bucking is I superglued the last 3 mm of the bucking to the barrel (The side where the bb exits).
The bucking lasts long enough to switch out with a New one whenever i need it removed and the glue comes of the barrel very easy.
Normally I shot 1.7j with 0.30gr and 1.12j with 0.40. Now I shoot (had to rejust the adjustable springguide) 1.7j 0.30 and 1.63j with 0.40gr.
The 0.07 loss is imo escaping from the nozzle between bucking or cylinder head.
It a bit of a spartan method but I can recommend it highly
