FX fx impact m4 first 10 shots are slow

[brandanbooth]

Fx Airguns has released a fix for slow first shots.
There is 5 new pieces: not conical plenum neck (with just 1 oring inside), a delrin ring/insert that go inside that plenum neck and complete new valve housing and oring.
For the M3 the warranty only cover the plenum neck and delrin ring/insert, while for the M4 all the 5 pieces are replaced.
Cannot put photo because the dealer cannot allow.

I wonder if it's the plenum neck feed hole causing it I seen some guy drill it out to 2mm that he said fixed it

The plenum neck is the only issue, all other parts are not relevant.

It has been proven for so long. Mubhaur his part fixes the issue without replacing 5 parts.
