TX200 Transfer port

Tue Aug 07, 2018 8:02 am

Hi there i was stripping and cleaning a tx200 mk3 that i bought second hand its a 0.177 and was just wondering what is the normal size for the transfer port, having also got a Walther LGU that really needs opening to 3.2mm so was a bit shocked to find the tx was almost 4mm.
Thank you Graham.

It's not only the diameter but the length too that plays an important role.

My HC shows a TP of 3,75 x 9,80 / stroke length 86 mm giving a SCR (static compression ratio) of 390.
My LGU has a TP of 3,20 x 6,00 / stroke length 85 mm giving a SCR of 865.

Both excellent guns in .177 but the LGU (11,3 fpe / JSB Exact Express 4,52) shoots better and more precise as the HC is FAC (14,3 fpe / JSB Exact Heavy 4,52).
Live is a journey - not a destination.
