Things I liked:The equipment appears to be well made from stron material (braided hose) Things I would have changed:A longer hose would make the adapter easier to use. A bleed valve to remove pressure from the hose when finished should be added. What others should know:In this case I'm glad the hose is short. First time I used the adapter, I connected it to the gun and the tank, filled the gun, turned it off at the tank, started to lay the tank down to get a different grip on the tank to unscrew the adapter from the tank (slowly to bleed the hose), and the quick connect connector came off the gun nipple. Loud bang, hose whipped around but missed me, and I thought to myself that I was glad it didnt come off while the valve was still open and that I'm glad the hose is short. Don't know if it will happen again -I think the QD connector was firmly in place- but if it does fail again I will send it back. I have only used it the one time so far.
Things I liked:styling, weight, feel when mounted to shoulder Things I would have changed:the rifle didnt work - the gas piston was apparently not filled, or it leaked. I would have preferred that PA
had checked the product for function, especially since this one was to replace a first one (bought by my friend) that also didnt work.
