M-Lok rifle hand stop - long version

An M-Lok rail mountable hand stop for your rifle's hand guard. Improves front hand grip on the handguard, helping with stability during firing. 

You will need two M-Lok screws and T-slot nuts (e.g. the official replacement screws available from Magpul) to attach. Designed for an imperial #10-24 button head hex cap screw (with 1⁄8" hex key spanner), but can probably work with similar metric sizes of screws and nuts. 

Recommended printing instructions:

• Print with PETG, ASA, ABS or anything with reasonable strength and UV / heat resistance. 
• Use 0.2 mm or 0.3 mm layer height; You can print with a 0.6 nozzle, but might find it harder to get the M-Lok nuts to tighten given the small tolerance of the nut clamps)
• Print upright at an angle, with the model laid on the back surface as show in the screenshot
• Enable tree support, if supported by your slicer - with OrcaSlicer the organic tree support helped produce a very clean print and was super easy to remove
• Use 4 perimeters and 25% infill for strength

Unlike the original short version, this version does not have a sacrificial layer in the screw holes, and no post-processing is required. 

Getting the t-slot nuts to stick after a quarter turn might require multiple attempts, but the screws should eventually grip the rail tightly. Do not over-tighten.
