I have also successfully adapted the Crosmsn/Benjamin BT !500 gas spring into both the 130/135 and 125. These are the units in the Benji XL guns. These things are cannons when done, and the BT should outlast the Vortex by a wide margin....

The Gamo gas spring has been successfully adapted to a Hatsan 125. Shoots hard and should las a ton longer than the Vortex....

I have successfully adapted Crosman NP rams to Hatsan Strikers and 95,s that have dead or dying Vortex rams. However the NP's don't have sufficient stroke length to replace the type 2 Vortex units in Mod 125 or 135. I have acquired a Gamo ram from the Hunter Extreme. I believe it has...

I didn't go that far.......sorry.......

As a ps ...i have found that soaking the rod gland in acetone for about 3 hours swells the O-rings and makes the easy to remove!

Yessiree. I now have the experience to know to NOT EVER TOUCH AN ASPEN/FREEDOM AGAIN.....

I more or less finally got the balancer tube sealed and pre-charged...that required a special probe. Assembled and aired it up. All went well....for a while. Apparently the pump check valves needed their O-rings replaced, as air would leak back into BOTH sides of the pump. After pressurizing the...

Well, only partially fixed.......... There is this little tube under the barrel called a "balancer tube." Its function, I guess, is to provide some sort of assist when hand pumping against a pressurized main reservoir. i replaced all the O-rings except 1...the ball check valve O-ring. TRY to...

I am waiting for a fill probe to precharge the "balance" chamber.......something I just learned about... I guess it makes pumping easier ?? Interesting stuff......

I see quite a few Ruger Air Hawk Elite II rifles for sale with upward bent barrels.......... I have straightened a few.......

I was dismayed when contacting Umarex in search of gas springs for their entry level rifles...Octane, Blackhawk, etc. I was told that they did not have parts for those rifles....... It really hit bottom when I called looking for a breech seal.........same reply. I was invited to send in the...

I resealed the Vortex gas spring in a ,25cal Mod. 135. Turned out nice! Charged the Vortex to 2100psi. Shooting 19.91gr domes pellets at 780fps. 27fpe. Not bad........ Good looking rifle. I still have a time getting the breech pins back in...

I only charged the Vortex gas spring to 1800psi....needs 2100........ only shooting 700fps 19.91gr pellet...
