Few kits are tooled at 1:24, which makes honest armament all the more worthwhile. Look through 1:24 aircraft model kits, find smaller and larger calibres in the turned barrels for aircraft overview, and reach for pin vices and tweezers in modelling tools when drilling and seating. Glue the heavier parts at this scale with epoxy, since cyanoacrylate may not hold a long barrel.
