We had somebody here just recently with a similar problem Is the gas tube lined up straight?
if the rail is canted then the barrel nut isn't lined up correctly as well (unless you have a defective RAS but I dont think this is the case)
I remember the other guy who posted this too.
I still don't see how it's mechanically possible. The gas tube goes in the upper at top dead center. The barrel nut has to line up to the gas tube hole. And the KAC rides the gas tube with the latch straddling the tube on either side.
The gas tube hole in the upper would have to be off center for any of this to get out of whack.
you guys talking about the larue rail? i was really hoping to get my hands on it... but now i'll just have to dissassemble one to try to duplicate. going from memory, and the diagram of larue's installation instructions, i just dont see how it's possible either..
it's kind of driving me nuts
HOW off is it? can you get a pic of the rails long-wise? i've never done a KAC rail, so i don't know how they attach.. but generally, if it's just off by an emem or so, just loosening up the screws or lockring or whatever holds it on, bridging the gap with a rise or mount or something, and tightening it back down will fix it.
:confused:only problem I had with my KAC hand guard was I didn't have a hand guard tool top rail went in fine after I removed the locking screw. The bottom rail I cursed for about 2 hours before it finely slipped in very next purchase was the hand guard tool [ I am not going through that mess again if I can help it]
markm right i would think that the barrel nut not being timed right would bend the gas tube and cause a problem with the gas key.
This is not an airsoft kac rail is it. Just asking ..
What profile is the barrel ??
I think the KAC is only designed for the GI profile barrel.
