Trigger, Sear, and Trigger spring

 

Lock Frame and Bolt. Definitely use carbide this endmill was trash when I was done. The bolt is hard.

From this pic you can easily see the channel created to clear the raised section of the semi RSP 

 

Fitting the bottom plate

 

The best 500 bucks I ever spent.

 

Bottom plate Rivet holes counter sunk so rivets are flush with plate.

 

  

 

 

Getting ready to rivet the bottom plate.

 

I'm glad this part is done! I think it will look fine with a little finish work and Parkerizing.

 

This is the riveting tool I made. It works in a muffler gun.                                   The trunnion Rivets are much easier. A steel block and a hammer.

 

Cutting the trigger slot to the new width after welding. 

 

1st Time out! It sure feels good when you pull the trigger and she fires and everything works. Still needs a little work on the trigger.

 

I took some more off the trigger to clear the bottom plate. Ran 75 rounds through it with out any problems.

 

Parts blasted and ready for a bath

 

Warming up the bath.                                                                                                                         Below the bubbles and fizz are the parts.

 

Not bad I guess for my first time over all I'd give it a "B"
