More Alfa adventures! I was trying to see where the Alfa falls off its regulator. It never did. After a 200 bar fill from my Nomad II it finally vented on the 120th shot (FX chronographed it at 400 fps) with Crosman Premier 7.4gr Wad Cutters. There was no telltale vertical stringing of shots on the 10m target like my Bandit or Marauder when they fell off. The Avg: was 424 fps with a STD Dev: of 16.7. I'm a target shooter and I'm trying to find the point that the group starts to open up. Maybe my methodology was wrong? Id' rather not shoot strings that long to verify when I could spend that time practicing. Everyone stay well!
I just received (PCP newbie) and filled (200 bar) my Alfa Proj and it dumped its air (vented out the barrel for 1-2 seconds) on the last shot. I probably got at least 80+ shots before this happened. Is this normal for a PCP gun? I paid the for 10 for $10 service so I'm thinking it shouldn't be a lemon. I love this community! Everyone stay well.
That is normal. You shot it below the pressure to seat the firing valve . Only shoot about 60 to 65 shots in a Alfa Proj and then refill.
Will this work with the Air Venturi G9 Hand Pump, or will an adaptor be needed? thanks.
You will need this adapter to connect to the G9. Air Venturi Male Quick-Disconnect, 1/8"... $9.95
How do I mount a dot sight on this? Rail looks close to 13mm.
The rail is 11 MM . You need a adapter like UTG New Gen Dovetail-to-Picatinny/Weaver Adapter,... or BKL 3/8" or 11mm Dovetail....
If you added the male quick disconnect to the gun would it work??? It looks like it has a cover of some sort over the fill probe...
You can just add this adapter to the fill probe that comes with the gun: Air Venturi Male Quick-Disconnect, 1/8"...
when should I stop filling the gun, to what psi?
According to the manual, max operating pressure is 200 bar (3000 PSI)
When I charge the gun, I can hear the air leaking from somewhere in the pistol. I checked and lubed the O ring where the reservoir attaches to the action and it contiues to leak. Any suggestions?
Try cocking the gun first
How do you fill the gun with the adaptor provided. Mine bleeds air and can't form a seal at the adaptor. Review the instructions and you will see a different adaptor.
Lee. You can use bees wax or clay to plug up the hole inside the fill adaptor. That's what I had to do to fix the leaky adaptor. I use the bleed valve on the pump or air tank instead of the one on the adaptor.
How many shots can you get on a full tank?
I have a din valve scuba tank. Do I need any special adapter to fill the Air Arms Alfa Proj PCP Pistol?
