AR15 80% Lower – Milling Trigger Hole and Sandblasting.
The final step in milling out the 80% AR15 lower receiver is milling out the hole for the trigger. When using a lower quality drill press make sure the end mill bit is tight in the drill chuck. Some people have had an end mill bit come loose while milling out the 80% AR15 lower receiver and it resulted in a destroyed AR1r lower receiver. Make sure that end mill bit is secure in the drill chuck. Also use plenty of lubricant when milling out the 80% AR15 lower receiver. I used automatic transmission fluid for cutting oil for milling the 80% AR15 lower receiver. The jig for milling this 80% AR15 lower receiver is ‘the Original Blue Jig’ and is a high quality jig for milling the 80% AR15 lower receiver. After the milling process was complete on the 80% AR15 lower receiver, the now completed and fully functional AR15 receiver was chemically cleaned and degreased of the milling oil. I then lightly sandblasted the completed and fully functional AR15 receiver with play sand at 80 to 90 psi with a $20 sandblaster. You only need to make the bare AR15 rough enough so that whatever coating you use will adhere well to the gun part. The next step will be to immerse the AR15 lower receiver in a degreaser and blow dry the gun part. The part will need to be handled with latex gloves so that no oils contaminate the gun part before it is coated. The gun coating I will use is DuraCoat, which is a 2 part epoxy and is one of the better gun (firearms) coatings. It was obvious, after sandblasting, that the amateur milling work on the 80% AR15 lower receiver was high quality and accurate. You can’t go wrong milling an 80% AR15 lower receiver when you take your time and use the ‘Original Blue Jig’.

This mold making tutorial video shows how to make a two piece silicone block mold using Mold Star 15. The finished mold can be used for casting resin, wax, foam, and many other materials.

The original model is a plastic sphere. The 2-part mold should be split along the horizontal axis.
