M4 shell adapter for firewad

Описание

this is a M4 adapter made to fit almost perfectly with Firewad's M4 lower for the AAP-01 The nozzle and the release are suplied as STEP files so u can change their dimensios to better fit your shells and conditions. if you have any questions/sugetions or probles please let me know down below and i'll reply as soon as possible it uses: 2x M2.5 screws (one has to be at least 16 mm long) 2x 4.5 mm OD 0.5 mm Wire Diameter 15 mm Free Length compression springs 1x M2x23mm pin keep in mind that this is made to be used with the M4 lower for firewad and i cannot assure that it'll work with other replicas that use M4 style of mags 05/12/25 hot fix, now the shell should be ejected without any issues. 22/12/25 made a version that has one (1) extra spring in the ejector to make it easier to eject the shells (als makes for a great fidget toy)
