    Why would you want to fit the KMR on an HK416? Even if you "forced" it on there, the top rail would not be even since the 416 has a taller receiver. It would be a ghetto solution at best and not worth the benefits of weight or profile.

Especially, because I did not notice any myself, nor had feedback from military users around here about problems coming from handguard design on HK416* (and believe me, those guys are very vocal about anything bad that happens to their 416s).

    * - other than early production, non-captive crossbolt coming loose sometimes, but this seem to be solved long ago.

    However, with how your handguard profile is designed, with like what 345dgr(?) of uniterrupred circumference around barrel nut, there actually is no other (good) place to put cross bolts and tension it around it. So befits or no, this is most logical place to put nuts in your specific design.

    BTW Can you answer my question from previous post: "What is barrel nut OD in KMR and distance from bore line to top of gas pipe channel?" I was wondering if KMR can be somehow forced on 416. You know, men is always stronger than matter!
    Wouldn't work....The inner diameter of the KMR isn't big enough to accommodate the 416's piston. Not to mention, the rails wouldn't line up with the receiver.

The KAC QD suppressors also used a similar feature for fastening, though with a cross-gate rather than screws or pins. Many pintle mounts have used a similar setup since who-knows-when, with a pin in a groove to retain the pivot mechanism. Point being, it's not a new design nor unique to the 416. The position of the screw over the top of the barrel nut rather than under it is a significant achievement in any case as no one else had yet fit it all and the benefits of doing so are numerous.
    Since the 416 has been mentioned.....any chance Bravo would ever consider designing the KMR for the 416/MR556/MR223. I just installed the KMR on my Colt...unbelievable system, and it sure would be nice to have one for an HK platform as well...even using the current barrel nut like the Geissele rail does. I realize the design would need tweaking as some have already said but man, the KMR is awesome.

    -masking tape removed original finish: now it's "custom"! (people pay extra for 'custom').

    Funny thing, if you actually read this thread you'll not only discover that it wasn't the finish, but a color coating applied over the finish. Last I checked people don't want a white handguard so BCM used a coating that sticks pretty well to the closed pore finish to give it a basic black look.

    The original poster was satisfied by BCM's explanation as to what exactly happened and was more than happy to rattle-can the exposed white.

    In other words he was satisfied with the "its easy to fix our **** up," explanation.

    I'll always fix something myself. I absolutely HATE having to return something to get looked at. Granted, someone in finishing probably touched that specific spot with bare hands or somehow the part wasn't clean.... but shit.... that's cosmetics. I only wish I had the time to make that a life problem.

    To echo that sentiment, we've been trying to duplicate this result and have not been able to. Based on the thousands of parts we've had made and the number that have been subject to solvent soaks, paint jobs, adhesion and abrasion tests, we're confident it was an isolated incident. The unexpected (and sometimes unexplainable) happens at some point to any product.

    What's important to us is that at the end of the day, the customer is happy. That seems to be the case in this event. If that was not the case, BCM has a pretty good reputation when it comes to turning a frown upside down so I'll let that speak for itself.
