Sten Gun Picatinny Rail Attachment

thingiverse

Picatinny rail attachment for a World War 2 British Sten Gun MkII, MkIII and MkV. Five slotted rail, hinged so it can be placed behind the magazine well. **Use any 1/8in dowel or large cotter pin for the hinge** or print the 'StenRail - Hinge Pin'. The width of the bottom is 3/4in and fits right in between the ejection port and charging handle slot. **Use a #5 nut in the bottom.** I don't think heat from the gun will be a problem given where its suppose to be placed but **use ample infill** anyway after all its going to be holding a sight/scope. Top Versions: 1.  [StenRail - Top.stl](https://www.thingiverse.com/download:6634584) This top is the tallest and most bulky but also very sturdy. 2.  [StenRail - Slim Top.stl](https://www.thingiverse.com/download:6642257) As you can see its shorter than the previous verions but still very strong with proper infill. 3.  [Wide Top.stl](https://www.thingiverse.com/download:6650366) This version is .2in wider and will has a larger ID so the sight/scope and bi-pod are perfectly vertical. This top will only work with the corresponding bottom ([Bottom_w-Rail.stl](https://www.thingiverse.com/download:6650367)). As pictured the bottom also has rail, this can be used for grips or bi-pods. If you have any fitment problems please leave a comment!
