I just measured the main barrel at 680 mm and the pumping barrel at 500 mm (calculating from the image because I dismantled the gun only partially to measure only the main barrel), same as yours Pete. A actually get L=680 mm * 1039 Pix/1442 Pix (from number of pixels) = 489,95 mm.Now just referring back to the photo above with my gun and Tomislav's gun "side by side" I am surprised that no one noticed something rather significant. Tomislav's gun has a later version of the power regulator block, but it has the same length nose on the rear handle as my gun. That "long nose" lines up with the end tip of the passive line clip, whereas the front face on the gun that DG modified would be behind the clip (and it is for one of them, but the other one has had the clip cut off). So there are now three versions, long nose-flat regulator bulkhead, long nose-hollowed out regulator bulkhead and short nose-hollowed out regulator bulkhead, but maybe not the same bulkhead. I think Tomislav needs to measure his barrel lengths as the deeper revised bulkhead must take space away from the pumping barrel unless the gun is of a slightly different length, however the main barrel length will answer that question. Unless of course the regulator bulkhead is hollowed out at the back, but is not any thicker than the flat version and the combined gun photo seems to show this, in which case the barrels will still be the same length.
Pete here are both bullheads, your and mine, side by side. I would say they are same. Height to width ratio from the image is very close in both cases. Your gun is same as mine but your is nicer, in better condition, like a new.What is the thickness of the power regulator bulkhead as that determines everything else?
Here are some dimensions. Mine bulkhead is hollowed from the front side! I did not took out the bulkhead because it was very tight in 40 mm barrel. I could not remove it easily so I left it in place. 14.8 mm dimension might be slightly inaccurate!?I suppose we are both talking about the same Mirage. This is a photo of mine after I bought it.
I can not remember exactly but I think neither mine had the sealing O-ring on selector rode? It had not O-ring between two tubes. I did not check if there was O-ring that acts as gasket to seal the rear tube in handle. Maybe it is still there?
