Airsoft AR-15 Stock Wobble Retainer Screw

A simple screw for airsoft AR-15 style replicas that have a wobbly stock.

Most airsoft AR-15 replicas have stocks that wobble a little bit; most of them also ship with stocks compatible with crane style batteries which feature a hole at the top (where you rest your cheek). Most often than not, that hole can be tapped to accept an M9x1.25 screw (M9 screw with a 1.25mm thread pitch).

Once the hole is tapped, you can print this screw/knob at 0.1mm layer height and thread it in to prevent any stock wobble.

The screw being made out of plastic and the buffer tube being made out of metal (most likely) means that you won't leave any distinctive marks on your buffer tube… Unless you chose to use a metal screw, WHICH I STRONGLY ADVISE NOT TO, as you will SCRATCH your buffer tube.
