Derya TM-22 - Shorter M-LOK Handguard

Did you buy a Derya TM-22 with the long handguard, and immediately find yourself wishing you had the short handguard instead?

This handguard has M-LOK slots on the top, bottom and sides, including a half-size slot for mounting flashlights, or other accessories. It also includes an integrated barrel ring, because I've seen discussions online where people mentioned issues with their barrel fit after removing the barrel ring from their stock setup.

You have two ways to mount this handguard:

• An M4 heat set insert through the top slot – this is how the stock handguard mounts to the upper picatinny rail of the receiver, and will let you reuse the M4 socket cap screw that comes with the rifle for this purpose.
• Two M3x25 socket head machine screws and M3 nuts – this allows you to tension-fit the handguard instead (as seen in the pictures). I prefer this method as it feels more secure, and also means you don't need to f**k around with god-damned heat set inserts.

Other important things to know:

• I used PLA, but it'll probably work in PETG, or more turnt-up engineering filaments.
• I printed at 40% infill, with at least 3 outer walls for rigidity. You could probably get away with less, but I wouldn't risk it given that it's meant for mounting M-LOK accessories.
• Avoid over-torquing your accessories to the handguard – I use about 15 inch-lbs of torque (1.7 Nm for my metric homies, but my accurizing torque wrench was made in 'Murica).

Do whatever you want with it, just be cool and be safe!
(Also, post pics of it on your gun 'cause that would make me happy)
