may also be employed in conjunction with a drawn reciprocation dingle arm, to reduce sinusoidal repleneration
The roller-breech as used on BSA SuperStars and some Gamos is a safer method of getting direct-loading, but I think it still has some efficiency issues because of the length of the transfer port. This design could be worked on to give a shorter TP with some imagination, but it might be a little more complex. Sliding breech is cheap, works well and apart from the finger-chopping potential, does the job extremely well.

The system that the hatsan torpedo uses looks good

allows direct-to-barrel loading but none of the beartrap issues. Maybe a bit lighter too, as it doesn't need a separate compression cylinder

I have been studying the pictures and thought, no, they CAN'T have made it with the barrel sliding back and forth with all the slop that would imply, yet it cannot be a sleeve as that would mean about 10ccs of dead space between the transfer port and the breech... so you are telling me IT IS a sliding BARREL like a flippin Crosman M1 BB gun? Oh very dear me. First Webley-style trap-doors, now this.Only problem is that it is not a fixed barrel

Always looking for any cheap, interesting, knackered "project" guns. Thanks, JB.

Busted! you're right of courseOnly problem is that it is not a fixed barrel
The amount of "slop" introduced would depend on the engineering standards,
but it seems such a simple system, it can't be that difficult to get right?
Surely it's much more difficult to make an accurate break barrel, where the slightest "slop"
in the pivot translates to huge inaccuracy?

Modern, well made break barrels are better imo. Direct to barrel, shorter TP, faster to reload and just as accurate.
