As I recall that barrel was made by Prexis an it was incorrectly short chambered an had other issues as many of his were an he eventually got a second barrel . Ill let him tell the story on how long it took to get the first an the second replacement barrel an what he had to do to make it all work as I don't want to give out incorrect details on this particular barrel. I just know it was a screwed up mess form what I read on other sites.Warwicken, damn. Were you able to resolve the problem with them?
Point is if the OP had a round not chamber after it was laoded an it did not go bang then it did not go bang if he could make the hammer drop as the carrier would not go forward as that requires the bolt to rotate an that is needed to make the firing pin exposed to the hammer .
Im seeing a guy just trying to get even with IO at this point as he dosent seem to be replying to any one here .
Il stay out of what I think of IO for now . plenty of that shit on AK files .
Unless the tail on the carrer is broken or there is some other very obvious defect that could be seen in the two times it was supposedly sent in then some thing is not adding up .
Even if held limp wristed the gun should not double . It should not double no matte how you shoot it , If the carrier travels back far enough to cocking the hammer it should not double . Limp wristing it might affect it cycling but I have never been able to to make one do that . I shoot these rifles free recoil a lot . that means no very little if no shoulder force on the stock no second hand on the fore end off a bag an I have never had a issue with short stroking .
