Alliance Hobby is open and operating during the COVID pandemic.I already worked from home to begin with, so this is old hat to me.Having said that, business is actually BUSIER than usual.I am trudging through orders as quickly as I can. Email me with questions.
The flat man pack is a flat top vale and piston kit... "The idea is that by giving the gun a larger air reservoir, you can do more work per pump, resulting in the same shot velocity with FEWER pumps. Or, increase velocity with the same number of pumps over OEM."The PPPP uses a standard valve that has been reworked... "high performance aluminum valve (with an enlarged chamber to supply more air per shot), The valves are generally safe up to 20 pumps. Enjoy that extra velocity boost, if you want to take the time to pump that much."
I placed an order in May 2021 and haven't received it. I sent several e-mails requesting the status of my order but no replies.Fortunately he hasn't billed my credit card.My personal advice would shop somewhere else.
Update. This guy will not refund my money or reply to my emails. Stay away! 100 bucks down the shitter.
