Volquartsen Bolt Stop

thingiverse

For a Ruger 10/22 with an aftermarket Volquartsen bolt. When firing suppressed, you can reduce additional noise by forcing the bolt to remain shut during action. This reduces mechanical noise as well as forcing expelled gasses to exit through the baffles. This device braces the frame to the charging handle forcing it to remain shut during firing. You must then manually remove this magnetic device, charge the weapon, replace this device and continue firing. It's meant to keep your hush gun real quiet at the cost of speed. This small device includes two 6x2mm cylindrical cavities to embed craft magnets into. I'm using these: https://smile.amazon.com/gp/product/B07CVPC3YJ This is currently a prototype and still being tested. The difference between a generic Ruger bolt stop and this Volquartsen specific one: The Volquartsen requires 40mm in length while the generic Ruger one would need to be 43mm. When slicing your gcode, set a filament change at the top layer that the magnet cavities are exposed (Prusa Slicer - unsure of others). Once you export your gcode, you open in a text editor and search for "M600" (instructions for a filament change). Since we don't care about removing filament and re-feeding, you may optionally comment this out with a preceding ";". What was: <pre> M600 </pre> Will become: <pre> ;M600 G1 X10.000 Y100.000 E0; parking position M1; user stop M105; return to current temp </pre> Once the printing pauses, insert one or two magnets and resume printing.
