Another barrel wobble thread
 

So I'm still assembling my KA M4. Now I have a DD lite from Socom Gear. From what I can tell the ring that holds the back part of the rail onto the receiver and also locks onto the barrel can't be screwed tightly enough to stop the barrel from being able to move. The barrel can only move about 2 or 3 degrees from 12 o clock but it does make usinf the iron sights hard. Can this be fixed while keeping my DD lite?

sounds like the same issue theguy had heres the thread

apparently spacers can remedy the issue

Was about to say, Although mine was a DD MK18 RAS.

Again on a KA body. Huang is sending me the shims I need, ill update if it remedies the situation.

well m m16 barrel has started to wobble.... i obviously hate this what should i do

how can i correct barrel wobble on my m16

There are a few options.

You can attempt to tighten the nut and the Delta ring at the front of the receiver. Over time something may have become loose and your barrel may wobble due to this issue.

You can remove your hand guard and tighten any loose screws that may be in there.

If you have a plastic/polymer receiver at this time you can opt to replace your receiver with a metal one and also replace your barrel with a 1 piece metal outer barrel.

Or you can do this.
