See Part1 and Part 2 Painting the Receivers In previous steps, I gave you the links on where to buy the fully welded and ready to go receiver and a completion kit that contained the parts you needed to build the Uzi. In this part, I go into surface prep for the receiver and pistol grip.
The McKay Receiver came unfinished and looked like this:
So I found some NITROCELLULOUSE GUN COATING: at D+D Sales for $14 a can. One can would do several complete uzis. Here are the specs:
- Bonds to aluminum or steel
- No baking required:
- Ready for assembly in 1 (one) hour.
- 1 hr – Very High Resistance to gasoline and oil.
- Paint Receiver, individual parts, and barrel. Thin coating allows painting inside the receiver and all other gun parts. Use single coat on internal parts or 2 light coats to allow free operation of parts. Use multiple thin coats for best results, where binding of parts is not a concern.
- Post application temperature tolerance 250 degrees.
- For optimum bonding sand blast before painting or sand and clean with course steel wool and clean with lacquer thinner before painting.
- IF SAND BLASTING IS NOT POSSIBLE: CLEAN WITH course steel wool and Acid wash with DILUTE muratic acid (HCL hydrochloric acid), (Pool acid). Dilute to 1/5; (Some bubbling will occur; remove after 15 minutes.
- CAUTION:Do not breath fumes and use Rubber Gloves. Very hazardous if inhaled and it smells pretty bad.
Here is the receiver after several light coats. Here is the pistol grip/lower receiver with the paint still wet. I had to take all the parts off to paint it. If your Uzi Cover is beat up, you probably want to take that apart and paint that as well. Magazine Catch, Semi Automatic Sear, Trigger and grip safety Assembly This diagram should help you assemble the rest of the internals and grip safety. Put the mag catch on first. The order you assemble the rest of the components have to be in this order, otherwise they don’t fit.
- Grip Safety, and spring. Attaches in the rear.
- Selector button and lever and spring. on the side of the stick
- Sear and pin. Inside the front of the receiver part.
- Trigger and pins. Near the front
- Grip and screws. On the outside of the stick.
- Now you have a completed lower receiver pistol stick.
The next chapter will cover assembly the upper Uzi receiver.
