What is the point of buying a 'lego' rifle if you can't replace the parts on it, yourself? I'm asking for advice from someone who may have already solved this 'plumbing' problem. I'll solve it myself, if necessary - I'm just trying to reduce the pain of this learning experience, as much as possible. :jester:
The barrel nut below is similar to what I have, in that it has the jam nut that threads onto the hand guard and is tightened to secure the hand guard, but different in that I think there must be no threading on the muzzle end. The one shown here is for a screw-on full diameter quad rail, whereas my rail is a small diameter with a channel for the gas tube/block which eliminates the possibility of the hand guard being spun on. It is simply secured by the jam nut and a tight fit on the sleeve that it slides over, plus one hex screw at the bottom that clamps the handguard to the sleeve to hold it in place while the jam nut is tightened.
The hand guard below installs similar to mine, except mine is a narrow diameter that doesn't spin on over the gas tube/block.
