I’m building an AR pistol upper with a 9” barrel, but are torn between the 8” and 7” KMR-A handguards. Anyone can share a picture of a 9” barrel with either of the two handguards? I know the actual length of these handguards are longer than what their names say. So I hope to see exactly how much a 9” barrel extends from the handguard, especially the KMR-A7. All else being equal, I probably would choose the shorter one just to minimize the weight. But I want it to look good as well. Thanks.
