Does anyone know the size of the thread on the barrel and where I can buy an adapter for it?
If your looking for moderators for the barrel, thread size is 1/2 UNF . You might try the internet for moderators. P.A. also stocks a foster fill adaptor (PY-A-2841) so you don't have to use the probe that comes with the rifle, makes filling a lot easier.
Do you have to buy all the accessories before shooting the air gun?
You need a way to charging the gun (pump, tank, etc)
How do you install a quick disconnect on the sumartra
It's very easy: insert a screwdriver in your fill port as a lever and crack it loose, unscrew by hand. Take out the old o-ring and install the one that comes with Pyramyd's AVMaleCoupling [PY-A-2841] (or other Foster adapter Pyramyd's is far from the only one you can get but the recent price drop does make it the cheapest...), screw on hand tight, and then snub it on firmly with a wrench (not too tight, or you could damage the threads) that's it! No need to de-air the gun as the fill check-valve is a separate assembly deeper in and will not be effected by replacing the fill port.
Is there a silencer available that will screw onto the threaded barrel of this rifle
Pyramyd doesn't offer one.
i really want dis gun but no one can give me a strait answer when its gone be in stock i got 5 tins of pellets .25cal does anyone know?
Looks like it should be in on 1/30/15
Where can I buy a single shot tray thanks in advance
I am not aware of any being available for this model.
What's the fpe lost from carbine being about 5 in shorter in 25cal
That is a difficult question to answer and has many variables. I would suspect a minimum of 100fps.
You lose around 90 fps.
How is the Accuracy effected? Looking at the 12 shot speed chart done by your Tech. Department. or to put it another way, If I aim "dead-on" at a rabbit at 75 yards, shoot 3 more times, than again shoot at a rabbit at 75 yards, is the point of aim Predictable? Is this a normal amount of "fps" change where every shot is traveling slower then the previous shot?
Yes, it is predictable and with a pcp rifle you can expect to have a change in velocity. The more you shoot and get to know your gun it will become second nature and you will know almost exactly where to aim
how does to pump for this gun?
it takes a while
whats the biggest animal i can humanly kill with sumatra 25 cal
You can take feral hogs with headshots and heart lung shots within 50 yards. But, you need to shoot slugs and it helps if you have the Sumatra tuned by Saddle Mountain Gunsmith. The tuning can be done for $200.
fox or coyote
