I am planning on installing a adjustable gas port on my Garand, and want to know if there is any advantage between the Shuster or Mc Cann system?

I have both types. I prefer the McCann type with the orifice inserts for the following reasons -

1. It is possible to remove / reinstall without losing the setting.

2. It is easy to switch between different loads by numbering the orifices and keeping track of which orifice is necessary for each load.

I couldn't tell the difference between them in terms of reducing op-rod impact or improving accuracy.

Others may have a different opinion, but I prefer the McCann.
