Front bench slight block for an AR-15 style A-Frame front sight. This block can be used to remove or install the pins to remove or attach a front sight to the barrel. I included a left and right version of the block depending on which way you need to press the pins out or install them. This block also has the holes to remove the gas tube pin and the sling attachment pin. I also included a support piece to help hold the barrel up during the process. I used this on my front sight removal and it worked great, so I figured I would share since the ones I found online seem either overpriced or not great. I printed mine out of PETG to make it tough. It probably could be made out of PLA, but I have not printed that. Let me know if you have issues.

IMPORTANT!!!! - Be sure to measure the pin diameter to make sure you are pressing the pins out in the correct way. This is not standard for manufactures.

So, uh, how is this supposed to work?

@Coconut

I am not sure what you are trying to show. If you import the .3mf file into the Bambu slicer it should have all the correct settings. It looks like you have no supports selected. Let me know if you need some more help.

Replying to @Coconut :

The blue is just a floating section with nothing supporting it. Luckily my printer handles bridging well. That's like a solid 2+inches of floating material. I imported your X1C directly from here and that's how the profile came. Assumed that was intentional since you put text inside the cavity.

(Edited)

@Coconut

You obviously did not load it correctly becuse the .3mf file has the supports selected to bridge the gaps and allow thick walls in critical areas. The text inside is only there because people rip my designs off. If you make sure supports are on it will print correctly.

Great print. Worked as described.

@TheIAmLink

The print profile printed fine using ABS. The design doesn't not play nice with a triangular front plate, so that will need to be removed or pushed out of the way. The holes are extremely oversized for a #31 drill bit for a taper pin.

I used this for driving out a gas tube retention roll pin with a 5/64" roll pin removal punch. The bench block worked great!
