125 sniper gas ram installed

Today I received news that my gas ram arrived and was to be installed into my Hatsan 125 Sniper. Well, to make a long story short it took some time to get this airgun into operation and function well enough to shoot. Tomorrow I'm going back and try to help remedy the problem. The 125 shot quite well for a little while before I encountered a problem with the cocking mechanism but, tomorrow is another day so I can play!
The gas ram I got is an N-force gas ram and charge at 170 bar. I have shot a series of 10 pellets using JSB's .25 cal weighing 25.39 grain and resulting from highest to lowest. Highest velocity 698 fps, lowest 686, averging 690.50, extreme deviation 10.00, standard dev. 3.72 and giving an average foot pounds of energy of 27.35. That's not bad and I hope it will only get better with time.

not bad,did you put the 28mm maccari seal in it?also did you set the pre-load at 10mm ?what kind of top hat did you use?did you hone the chamber?and keep a eye on the cocking arm loop,they will bend under extream stress i/e 170bar pressure,and won't let it catch the seer,because it don't go back far enough,also which way did you install the np rod first? or tube first?hope it was rod first"i know that it takes a few efforts to get things just right,and that quattro trigger can really be a head throb until you figure it out,your well on your way to getting your gun the way you like it,keep the faith and let me know if i can help..good tinkering,,lol.

Seems the cocking arm is the weak link. Maybe a better one could be milled out of some tool steel!
