I make these replica grenade bandoliers (not a sling) from time to time for various customers. I've owned production made slings so I took measurements from the real deal. I also make the replica grenades.
Also I make Arnolds pants belt + buckle as well as supply the correct style buckle for Arnolds jacket. (Not pictured)
In addition I make custom roseboxes for your rosebox shotguns or Airsoft replica. (I will take a better picture soon). It is very accurate and fits the Model 1887 replicas nicely.
Pictured is a custom 1911 I made for a customer to resemble the $500 airsoft version for under $200.
