robwelsh 354 Posted January 21, 2012 Report Share Posted January 21, 2012 my mate pumped is right up..it was ridicolous, he the put it down to 20ft lb mark, sound like a rifle lol he put it back down to 12ft lb then..at about 20ft lb cock it 5-6 times and youd feel it on the old arms lol Quote Link to post
Acuspell 329 Posted January 24, 2012 Report Share Posted January 24, 2012 If you over load a 12ft-lb gas ram you will burn the piston crown. For FAC rifles they use a totally different internal set up with different seals and a different piston. This is one of the reasons so many gas rams get trouble, people over pressurise them and do damage. My Theoben gas rams are 1986, 1995, 1996 and 2001 respectively an dnone of them have ever given any trouble - I think because I just leave them alone and use them. Most problems are caused by the nut that joins the sight to the trigger. Quote Link to post
