hey guys,
thanks for replies. for some reason i dont get notified when someone posts in my thread. nyways.
all is good, i followed Debrief 's instructions and the thing came off pretty easy. there is a little glue on the thread, so take it gently but firmly.
to answer some Qs: my stock fps is 425, bought it at milsig.ca and its the sexiest thing i held in my hand, worth every penny.
