3D Printed folding rifle stock

[Chuck Noris]

I wanted a pic rail mounted stock for a .22 rifle build I'm working on. Instead of just a PLA stock, or a bufferless AR stock, I decided to go with the AWCY MCX Alloy Slim stock. It's similar to the Sig stock (which is kinda pricey, IMO), and it turned out VERY well. I used Polymaker Fiberon PA6-CF20 filament, and the metal reinforcement sides were done by sendcutsend.com. I had them do a stainless powder coat in matte black. They did a GREAT job, and this turned out so well I'm going to do a brace version for a 10/22 charger pistol. The metal sides make this a very solid and sturdy, yet thin, stock. I am printing a buttpad and a cheek rest for the stock. I'll end up with about $55 in this, the SB and Sig folding stock/brace that is pic mount runs $200-$250 if you can find them.

Let me know your thoughts!

All I can say is wow! That looks amazing.

I'm in for two braces if you decide to sell some

Finished the buttstock and cheek rest. Final product!

Tell more about your printer and process. It looks perfect!

Bambu X1C. 0.4mm hardened nozzle. I prefer Fiberon PA6-CF20 filament for 2A prints. Go slow - don't try to print fast, I tried pushing it and got less than "first time quality" results. I use a 0.12 or 0.15 layer height, depending on the size of what I'm printing. And always anneal the finished product, it makes for a stronger item.

What process do you follow for your annealing? (What do use to heat it up, temps, durations, etc).

I put it on a cookie sheet, in the cold oven. Set to 200 F, leave it for 8-10 hours. Turn it off and let it cool down. So far that's worked very well. Again, that's for PA6-CF20. 200 would definitely melt PLA+ or PLA Pro.

The folding mechanism broke on my print and I have to print another Picatinny rail folding stock mechanism

Looks great. The metal sides should make a big difference. Considered attaching the metal sides to the hinge? It's the point likely to have the most stress.

How has this held up? I'm putting together a 22 also and am looking at different stocks to print. Debating whether to go with a fixed or folder.

I like the metal reinforcement but the hinge isn't as robust as I would like. I have started using one called the Chodin brace. It is imbedded in the "GRIP_RECEIVER_STOCK_BRACE" folder that is in the Chodin 10_22 Chassis Release v1.0. I have modified it so that the rear brace and the arm print together, then the hinge and button. I will upload pics.

Yeah, the more I talk to people about the printed hinges the more I'm thinking about just going with a fixed stock.

I'm putting together a Galileo R2 and really like the Rattler stock that's in that package.

Here is a 10/22 Charger, 8" Tacsol barrel, Faxon Firearms 10/22 receiver kit, Chodin Chassis (I added a pic rail), and a DBWave folding brace that I completely remodeled. I attached the butt to the arm, printed as one piece. Made the pic attachment where it would have 2 stabilization screws instead of 1. The release/catch button is very solid. The brace folds effortlessly, and very quickly pops back into place. Printed in Fiberon PA6-CF20. The grip is also PA6-CF20, just an AR grip print file. The attachment seems more solid to me than the one on the metal reinforced brace. I've done several of these and they are working well so far (few months, nothing long-term).

Very cool project
