xm204HP? mine looks different, also im having problems with stuck valves with c02

[Fox Hound]

i went and ordered these a while ago and i noticed mine looks different than the ones airsoft gi advertised

here is mine

and here is airsoft gi

Everytime i try to put in c02 the valve is getting stuck. also is there a way i can get a replacement o-ring for my valves?

don't know if this is your problem, but on CA grenades the unit carrying the valve has only one set of ball bearings to guide it resulting in potential misalignment; and therefore leakage. Madbull fixed this by having 2 sets of bearing to keep it aligned. Try playing with the trigger mechanism, you can always open and inpect by unscrewing the two halves of the grenade, just dont lose any bearings lol

i had a few of these brand new out of the box with the same problem. when i contacted my distributor to return them, i was told that a bad batch of valves had slipped through and that they had a lot of them returned recently. perhaps you can get an exchange on it from where you bought it.
