I did not want to steal the other guy’s thread, so I am asking this in a separate post.
I apologize for perhaps my ignorance, for I know there have seen many threads on “front band tension” but I still an unclear.
I have absolutely NO front band movement between the front band and the stock ferrule. No matter how I press (pressing upper band and lower hand guard together at the stock ferrule), there is no movement at all; the two are ROCK SOLID tight against each other. Again, ABSOLUTELY no movement up or down or side to side.
I have shimmed the gas cylinder so the front band has no movement on the gas cylinder, but the top of the stock ferrule sits against the lower bends of the stock ferrule (where the ends are bent to hold the upper hand guard in). There just is no place for there to be ANY movement, so that is where my confusion lies.
Reading posts (and http://m14tfl.com/upload/showthread.php?t=54400), it seems I should have pressure where if I squeeze the upper band and the stock ferrule together, there should be some movement with pressure. I must be missing something here, for the front band does not seem to have any gap within it where movement of the stock ferrule is possible. If I shim the stock channel, I’m not sure it that will really do anything.
In the link it says "Place a stand off spacer in the barrel channel midpoint between the rod guide and end of cyl." . I’m not real clear on what a "stand off spacer is (or what it would be made out of). I'm also not clear on how to do that, because I sure don’t want anything rubbing against the operating rod as it moves. It seems any shim would need to go under where the OP operating guide rod is, or under the gas cylinder itself, but not between the two. If so, what material would you recommend to shim?
Where do I have a hole in my head? (Please don't say all over :O) )
