Left Side charging handle for Ruger 10-22

grabcad

This part is designed to provide a left side charging handle for the Ruger 10/22 very popular rifle. It allows right handed people to perform tactical reloads with their right hand never leaving the pisto grip with the finger on the trigger in aiming position.Version 1 : tested and shown in videoVersion 2 : Not tested. Improvement to slider strength by relocating the holes on the slider. Added spring compatibility.I had this idea when I used to own an SKS rifle. It became a must for my Ruger 10/22. I obviously realized I wasn't the first to have this idea and that an aftermarket part already existed. This part is highly inspired by the already existing part out there.The design is in 3 parts to allow assembly of the rods when mounting it on the gun.The aftermarket part was designed with a pivatinny top rail. My design respects the shape of the original Ruger hybrid rail which is compatible with both picatinny parts and 11mm weaver rings.For the rods, I chopped fondue meal forks at 109mm, They are stainless steel with 3mm diameter. Just perfect! (And so cheap at the 1$ shop)See the video3mm diameter rods are a perfect fit with springs you can find in any cheap ball pen. You can use 2 or 3 of them on the left side (Version 2)The 4 screws of the original Ruger rail are compatible with this design.You will need an additional standard #5 wood screw to join the 2 main parts. I chopped a 5/8'' long screw to do this. It doesn't reach the receiver.The main flaw of this design is probably the weak dimensions around the holes in the slider. My first printed slider broke across the left side hole. ABS print would probably be stronger than PLA and I would advise to wash the part in acetone to reenforce the print layers.Enjoy all development Solidworks files, assembly file included!Suggested improvements :1. Reshape left handle grip to fit your own feeling. This one may be too similar to the existing part.2. Reshape right side slider puller to be more ergonomic for traditional right hande use3. Modify in only 2 parts : the main part with partial holes allowing rods install from underneath without joining screw.4. Add spring compatibility on the right side as well.5. Modify top rail with side wall rails and/or personalized angles/lengths
