I’ve got a lightly used JP MKIII AR15 12.5” modular handguard with a 0.750” Seekins low pro adjustable gas block (Sold). Looking for a longer, more low profile handguard for a varmint rig like a KMR or a geissele. Would trade rails or sell this rail for $125. Vltor upper and gas block/tube in pic are sold.
