Here is a 9.75" in AR platform handguard I modeled in Shapr3D and Fusion360. I needed my AR pistol handguard shortened a bit and didn't want the hassle of trying to find one, so I created one. It's a perfect fit and snugs up nice with the added holes for brass threaded inserts (M4x8x6mm) that were pressed in with a soldering iron, as well as two M4x12 Hex Socket screws.
