Several years ago I started using tripods for coyote setups and deer from ground blinds. I use the Armageddon Gear Tripod Scabbard (USMC issue) AG0110 @ $99.95 available is lengths to 32" ( Tom Fuller actually built a longer version to fit longer tripod/ball head combo.....Mod7 Hog Saddle; PIG0311-G Field Shooting Tripod; Ball Head GNN XB-52DL) and the Sniper Tripod Sling A0106 @ $64.95. Scabbard has Molle straps on rear to attach to ruck. Sling attached to the tripod goes into the scabbard. Use scabbard for humping gear to the range/field. Use sling between setups. Armageddon Gear is veteran owned by Tom Fuller. Makes great durable, field proven gear. Only change I would add to scabbard is a handle, as found on their Trojan rifle carrier, at balance point on front (opposite the Molle) to facilitate grabbing scabbard alone. Scabbard designed, manufactured for USMC doesn't require this, but I would find it very convenient for certain field scenarios. I actually added one to the special length scabbard.
Check out Tom's video on the Armageddongear.com sight for their Beer Bivy......hilarious!!! "Keeps your beer colder than your Mother-in-law's heart..."
