I started with a WA M4-Patriot. For internals, I went with -
- RA-Tech Steel Bolt Stop
- RA-Tech Hop-up Chamber
- RA-Tech Hop-up Rubber
- PDI 6.01 Inner Barrel (210mm)
- G&P 120% Hammer Spring
- POM Reinforced Loading Nozel
I also did some personal work on the bottom of the bolt carrier assembly and the flat-surface of the hammer to make the action a little smoother. I noticed there was some wearing and it made me nervous.
