Fuzzygeff's got a scoped AR.
The free-float is a YHM tube that has threaded holes in it that you can use to attach sections of P-rail. This same sort of rail section is what the bipod is attached to. There is also a sling swivel hole up front, but it's flimsy.
All up this rifle is near 12 pounds.
Attaching a section of rail to the side of the tube and using one of the left-over Sling Things in my parts bin gives a much more secure front sling attachment point.
