a couple of bits needed any mods

Hi I am getting closer to finishing off but just need a couple of bits if anyone is making them.
I would like a better saftey release as the origional one with the red end is hard to use and dammaged on the red tip.
also a breach cocking knob with a spacer preferably a bit chunkier than the origional.
anything to make it a bit more user friendly.
pictues would be great.
Thank you
