Sorry Guys you will have to go to African Air Ordnance facebook page to view the video

Nice and to think 3 years ago people said it could not be done I am glad someone else did it.

with the extreme I have shot over 1450 FPS with a 280 grain slug. Keep up the good work Helium is the future of big bore air rifles. I have the new booster in the works that goes to over 6000 psi and a proto type rifle to shoot these high pressures the numbers I am getting will blow your mind but that is for another day not ready to sell yet but we are getting very close to firearm capabilities.

If it can beat Markos benchmark consider my mind blown.

Helium is for guns that can't make enough power on air.

Texan valve I built makes well over 700 fpe on 3500 psi and made 908 fpe on 4500. 

How much more do you really need?

Soon we will run helium in it and I bet it makes 1100-1200 fpe on 3000 psi.

Then Marko probably do some tricks and get more power  nah maybe he had enough

[dyotat100]

Yeah not going to happen. I don't see them doubling what they make now.

Do you realize that a foster fitting that you are filling with is only rated at 4500 psi max?

Thanks Brent .

Awesome to see what 6000 psi will do

That is Awesome   
We are comfortably in the 800s fpe on air  and getting 5 heavy kill shots with around 4 usable shots after those 5  on a 490  cc  tank  so our air consumption is really good  this was important for a guy going out hunting in the field as its  not practical to be tethered to a 6l carbon fiber bottle    I have no doubt if we start running bullets in the 350 grain to 405 grain on Helium we will be in the 1200 + fpe  range       

[dyotat100]

I have your valve here and it is just a copy of the stock valve minus the return spring.

You need to check your chrony because it will not even get close to what you claim. Had a guy complain to me that he bought your valve because of Mr. Hollowpoints review and it didn't even come close to the numbers.

[MJP]

Well this is the reason we double check our numbers with chrony and Labradar.

Yep

Doug why do you have to be so negative with other peoples testing and products. I think that the use of helium is awesome and so do some others. For you to say that helium is only for air rifles that dont shoot good on air you wrong it is just an option for people to get ALOT more power.

This looks like warning to my eyes..

[Extreme Big Bore]

You do realize that there are many fittings out there that well exceed 6000 PSI ratings. I heard all the same things when I come out with the 4500 PSI fill a lot of negative things were said. Now look where the rest air rifle industry is heading higher pressure in a few years all the pressures will be higher.
