Hi,at the moment this is on hold,the adapters have 12mm-1.25 thread not 1/2" unf,the supplier can't supply the silencers so pretty much a no go,i can buy the nearly complete guns,no breech,barrel or pump head due to power levels,no fac etc,but again not enough interest to purchase 10 minimum and be stuck with loads of spares i cant sell,hth cheers Mark.
