In the end, a rifle which A: Functions flawlessly, B: Shoots accurately, C:Has compatability with parts, optional equipment and most importantly, with all ammunitions available are what the real criteria for a true tier 1 rifle should be.

There are a LOT of very high end firearms which do not function like a true Tier 1 gun should; from the 1911's that dot the firing ranges, to the 22 rifles that fill the sub-forum directly above this one, to the ar's of all types which choke on certain magazines or certain ammo.

So, look at the material and the make-up of the parts of each of the rifles, and their intended use to decide if they fit the bill.

Nowadays, a true Tier 1 rifle is the rifle with enough filled magazines to go with it to make it impractical to carry unless you get a wheelbarrow!!!
