Note: This riser has been tested on a Ruger M4-style stock. Please let me know if there are other versions of the M4-style stock that it does or doesn’t fit on! If your stock has a diameter of 36.5mm, it should be a perfect fit provided the oval slots are in the same spot.

Description:

Want a single riser that can do double duty? This riser lets you put your cheek where it actually needs to be, especially for prone shooting. The movable design allows you have the riser farther back on the stock to optimize for keeping charging handle capability, or flip it forward if you need extra length for your cheek while shooting prone. Depending on what your primary use case is, this one riser can meet both! 

This riser fits on snuggly, and removing will typically require a screwdriver to disengage the locking tabs. I left a little space under each tab so that a flathead screwdriver will be able to get underneath to remove the stock while minimizing damage.

Current heights available are 0.25, 0.5 and 0.75 inches. Let me know if you need a more specific size and I will add it to the CAD!

The riser will work in any common material, but I recommend PETG at a minimum if this riser will be doing more than guarding your safe so that it will survive high temps in your car or storage and be able to hold up to some bumps. Note that material shrink rates may vary. If you are unable to slip the riser over the stock and engage all the tabs into the stock, you may need to slightly scale up. I have included a test piece so that you can confirm your fit with your material if you wish before printing. All prints were tested with a Bambu PETG Basic.

All models are designed to print without supports with the “short clip side” on the plate and have been performing well with the following tweaks to standard settings:

Wall loops: 3

Sparse Infill Density: 25%

Sparse Infill Pattern: 3D Honeycomb
