It is time for a number of things all related to 5.56.
It is time to decide what rifle I buy next.
It is time to build and test against 5.56.
One important question in my head?
Can I build a unit that will be as light as I prefer and still stop the damn 5.56 out of a 20 inch barrel?
Here is a video about the rifle that I may buy next. It is in a set family SU16. I most like the SUA variant.
It is a rarely considered but very good choice.
