I've got an incremental update today, as my handguard arrived from Rock River Arms. So to have something to show you between now and the next shipment and completion of the rifle, I loosely threaded on the barrel nut and handguard.
Installation is pretty straightforward. The handguard comes with a special barrel nut that's threaded on the outside. Once the nut ins installed as normal with the barrel, then the handguard threads onto the outside of the nut. Once in position, two allen bolts clamp the handguard in place on the barrel nut threads, and presto!
The barrel assembly, gas tube (and pin), front sight post/spring/detent, sling swivel (and rivet), flash suppressor, and crush washer will be ordered tomorrow. It should all arrive in about a week, as long as everything is in stock. I'm getting close!
That's some smart diplomacy right there
