i recently purchased a new omer T20M 110cm gun. It came with an omer AISI630 stainless steel shaft size 6.5mm. I'm going spearing away saturday and sunday this weekend and they don't have shafts there for my gun. Today i bought a spring steel rife euro shaft size 9/32 X 60 this isint the same size diameter as the omer AISI630 6.5mm is it? It seems like it might be slightly thicker. Does anyone know if omer or some one else makes a 6.5 mm springsteel shaft.? The notches on the riffe shaft are also the little fins and the omer bands have a unique metal piece that goes into the original shafts imbedded non protruding notches and it doesn't seem like it would work very well with the riffe shaft because there would be a very small metal on metal surface area with the omer band notches. I can exchange or return it tommorrow morning before i leave for my trip but i need to know soon. not sure if the dive shop has the right one tho. I'm also afraid that using a wrong size shaft might screw somthing in the gun.
The Riffe Euro shafts are 6.75mm shafts, which are a bit bigger than the stock shaft, but still pretty quick. They are also a ton more resistant to bending compared to the stock OMER shafts.

With the stock 18mm bands, you'll have enough power to use the Riffe shafts. The notches work fine with the stock articulated wishbones too :D

If you feel uncomfortable, then try to find something else. Personally, I'd say use the Euro Shaft & happy hunting! :)
turns out they mis-labeld my euroshaft. it is 6.75 mm. I noticed riffe also makes a shaft called Small Hawaiian Single barb which is only 6.35mm. Is this compatable with my gun? Does it come in the length for a 110cm gun? I think i would rather have this one cuz it might shoot faster than the 6.75 euroshaft but still very durable b/c it's springsteel
Slings on T20 ( omer power 18 ) are wicked and they defenetely have the power needed for your thicker shaft.
If the riffe shaft fits the trigger mech nicely, the shaft should be fine.
