So I just took it out and put 100 rounds through it with the Surefire rail. I had previously zeroed the rifle with the plastic handguards and I had no zero shift. So I'm gonna let this sucker ride.
I have it tensioned to where there is the slightest tick of play in the rail, kind of like the plastic handguards have. And then have thread locker on the grub screws. There's no way the handguard can come off and it doesn't appear to be affecting the barrel harmonics in an appreciable way. I'm not planning on ever putting a laser on this rifle, it's just holding a 6P flashlight, so it doesn't need to hold a zero for anything. I can see how you could be deforming the barrel if you had it really torqued down on there to hold zero on a laser aiming module. Which is what I'm assuming the guys were doing in that situation. |

If I remember correctly Surefire was telling people the handguards were “semi free floating” and that the purpose of the screws was to make the barrel less susceptible to flex when tension was applied to the handguard, like a sling or a bipod.
But I don’t have much personal experience other than seeing them around and asking. |

As cool as the 416 is (even as an HK fan) I don't think the juice is worth the squeeze given cost and weight. The Maxim upper is awesome for achieving the 416 look without being stuck to 416 parts. You can run DI parts under the hood with 416 rails or standard AR rails (though a pic rail won't line up). My faux16 with Mod 2 guts for reference.

The vibe I'm leaning in to is an old Delta recce head sometime in the mid-'00s and they all get 416s. He wants to throw his on a diet so he has the armorer retrofit his 14.5 with one of those old Armalite tubes. So we're talking minimal modification based on what they would've done at that time to get it to work. Again, it feels like the juice probably wouldn't be worth the squeeze tho. |

You could just do what was really done, which is take a mill to the rail and shave off all the rail segments you're not using. It ends up looking like a 416/URX3 hybrid.
