If cutting the length, cut from the non choked end.

Could just be that the user has to drain the tank, remove the valve, unscrew the reg and then put it all back together once a month.

Dave

So having to take a few shots to get into the regulator isn’t a great issue, but obviously would be better not to fill through the reg.

What is that picture all about? did I miss anything?

Let the head scratching begin.

I cut the frame on my Talon just in front of the trigger group housing, and threaded it, I can now thread barrels in and out of the frame, I could add an M4 type rail system but for now I’m adding a free float tube and then a suppressor.

But if you want to use me to get around any import tax you might have to pay then that’s fine by me

$85 can get you a BSA barrel 24″ that is blued.

From what other poeple have told me, Gamo has been working with BSA for quite a few years.

BSA barrels are usually 5/8″ in diameter

They are choked, because they are hammer forged on a…Read more

Easy for me to get at a very reasonable price

Definitely a good idea for grips etc.

One thing I found interesting is that it doesn’t have a regulator (I don’t think) and I’m not sure if the firing valve is in the neck of the bottle or inside the body. Inside the body would allow the easy addition of a regulator.

The way that the AA S510 regulates its power is pretty crude, just restricting flow in the transfer port. It probably uses about the same amount of air on low power as on high power.

If you could list the FPS of a whole shot string, it would help us to see what’s going on.

What usually is going on, is that…Read more

Using yield strength gives the pressure at which the tube will permanently deformed and tensile strength gives burst pressure.

Just got to account for the wall thickness at the bottom of the threads.

Should be pretty easy to get a pellet sizer and sit down and size a tin of 500 in about half an hour

Had to cut it out with a stanley knife after cleaning it with vodka, still have the scar to this day 🙂

That was only a 50FPE .25 talon, don’t know what your 100FPE condors would do, but exceeding the speed of sound gets exponentially difficult when using ambient temperature air.

I say don’t bother trying to fix it, claim off those bastards

Then with the fill nipple pointing upwards, open the bleed screw on your pump/air cylinder VERY slowly until its only just bleeding out the air. This will drain the tank, if you…Read more

Other than that it has to be something to do with your hammer arrangement

If you have your original AF valve stem, try that in the valve, just pry out the stem with a flat bladed screwdriver and plop in the old one, take a few dry fires to seat it and you should be…Read more

I think I can also incorporate a link to the cocking and cycling mechanism into the forwards mounted scope rail meaning a 10 shot bullpup, letting me shoot all 10 shots without taking my eye off the target.

I have been around many good triggers such as Daystate and Air arms rifles and my trigger is up there definitely.

There is next to no spring pressure on the first stage, so little spring pressure that you can’t detect it with your finger. Then…Read more

Maybe casting bullets for my .25 would be a good enough improvement over diabolo pellets.

Dave

But it was put together so it must be able to come apart 🙂

How much better is the BC of the 6.5-7mm bullets when compared to a .25? A worthwhile venture into getting a new barrel?

Then take it to a machinist and get it profiled for your gun, also get the bolt modified.

Not too hard really, and very easy if you already have the tools yourself.

A .308 barrel has 0.0745 square inches of area where as a .25 barrel has 0.0491. This means that the .25 barrel has 34% less area for the air to act upon.

So in theory, just putting a .25 barrel on that 1200fps…Read more
