View Full Version : AIM Sports Quad Rail Too Tight??

May 26, 2017, 13:04
Hey guys I purchased the AIM Sports quad rail for my L1A1 and when I tighten it up all the way, my gas rod no longer moves. I'm guessing the rail squeezes the gas tube in such a way to stop the gas rod moving. Will filing out the top inside of the rail help relieve the gas tube, or do I need to tighten my gas tube somehow?

Diagnose the problem before removing any material. It shouldn't be hard to see what is binding.

Photos would help.
