11.5 Inch AR-15 Handguards

Every CMT 11.5 in. free-float handguard on one shelf: the TANO 11.5 in Tanodized hardcoat, the HDM 11.5 in black Type III hardcoat, the HDM-A2 11.5 with the ARCA-Swiss dovetail, and the UHPR-11.5 MOD 4 HDX hybrid quad rail. Each fits a mil-spec AR-15 flat-top upper, suits a 12.5 to 14.5 in. barrel on a carbine or mid-length gas system, and mounts on the CMT barrel nut with no timing and no shims. Building on an 11.5 in. barrel instead? That barrel takes a 9.5 or 10.5 in. rail from the handguards shelf.
