KWA M11A1 14mm Adapter

thingiverse

An adapter for the KWA/KSC M11A1 proprietary barrel thread to a more standard 14mm CCW thread. This allows for easy mounting of muzzle attachments (I use a spitfire tracer with mine) with no need for modification to the gun or attachments. **Creating the thread** The M11A1 barrel thread is designated as 5/8" - 11TPI. In Fusion 360 I added this as a custom thread by using the following dimensions: ``` <Unit>in</Unit> <Angle>60</Angle> <SortOrder>3</SortOrder> <ThreadSize> <Size>0.5660</Size> <Designation> <ThreadDesignation>5/8-11</ThreadDesignation> <CTD>5/8-11</CTD> <TPI>11.0</TPI> <Thread> <Gender>internal</Gender> <Class>6H</Class> <MajorDia>0.640</MajorDia> <PitchDia>0.59</PitchDia> <MinorDia>0.5175</MinorDia> </Thread> </Designation> </ThreadSize> ```
