I just got done cleaning my rifle length SPR upper for the first time today. I noticed the gas tube rattle a little bit, is this normal? The gun is shooting great. I just notice the wobble in tube when I was wiping out the inside of the receiver. The gas tube on my carbine is very solid, no movement at all. Probably just being paranoid, but if this can cause an issue down the road I want to be proactive. Any advice or experience would be great!

Thanks!

Scott
