Hello everyone,
it is not a novelty that the rapid prechamber in high power version is a bit 'insuffcent so I want to make a hypothesis:putting a quick fill and removing the valve from the cylinder thus allowing a faster inflow of air into the pre-chamber in the firing phase you could have advantages?. I don't know the caliber of the cylinder valve, I think the air passage is a little choked!.
Best regards.
if you mean valve chamber extension they work fairly good.giving around 30% better efficiency on reged High power.for example a .22 with19 inch barrel doing around 930 fps at 75 shots can go up 940 fps at 100 shots.full flow can just give raw high power and with no metering can give bad power curves and not so good shot to shot consistency
