The pic wont show anything thats going to be readily visible.
But I can tell you how!
the apoxie sculpt is a product available on amazon in 1lb amounts (good shelf life)
I used the black colored . There is a 4 hour working time after mixing 50/50. Hardens in 6 hours and cures completely overnight. I discovered that mixing with a small spatula and then using fingers to smash it around works best. the heat of the fingers appears to soften it some making it more pliable.
I cleaned out the hole (pin channel) in the upper receiver with acetone . clean well.
I used a small stainless welding wire, Or anything small and stiff , and place small "BB's " of the apoxie into the channel and molded it to the bottom (away from body of receiver) rolling the wire around inside the channel. If the material wants to stick to the wire. use spray silicone as a lube on the wire. Saliva works best. After getting it sort of placed, I used a drill bit (smooth shaft end) to do a final smoothing rolling it out inside channel. (use a lot smaller dia. than take down pin). You want to achieve a crescent shaped addition of the apoxie inside the channel. Thicker on the bottom and tapering as it goes up the sides. None should be applied to the top. It doesnt need to be thick. 1mm thickness in the bottom should be more than enough. I used the drill bit shaft like a rolling pin to smooth it and get it shaped. For the final, I assembled everything and hand held receivers tightly together. Spray pin with silicone multiple times and let carrier dry some.Then slowly twist pin across into place. there should be some material pushed out as its comes across. Rotate it as you go. Keep the left over apoxie material available to test for setup.
When your fingernail will dent the material, but it cant be deformed under finger pressure, rotate the pin to free any adhesion to pin and carefully remove pin. Separate halves and using a razor blade cut off any flashing from upper channel (saliva again works for a lube). Look for any other material that should be removed . re clean pin and lube it very sparingly. Reassemble with pin pushed across and in place and set aside for 24 hours. The hole (channel) should have a crescent moon shaped sliver of apoxie in the bottom all the way across and up the sides of the channel.
On mine, So far , so good. It's tough stuff. I've used it for bedding compound on rimfires .
One thing, if there are voids or missing areas, you can add to it and it will stick to itself. it just has to be cleaned of oils.
With the apoxie being black and receiver black, it doesnt show as a "modification".
I've taken the scorpion apart numerous times for cleaning and the apoxie isnt being affected.
hope this helps
