You'll also find the truth regarding the "Greatest Battle Implement" statement to be true if you have any of its contemporaries

Thats my WW2 Shooter Collection, took about 17 years to really get them as it is the main battle rifle for every main WW2 Combatant.
The prerequisite was to be un-mutilated, all headstamps and markings complete (Including German "Nazi" Waffenmat and Japanese Imperial Chrysanthemum). They all had to be built in 39-45.
The Top is my 44 Built Springfield M-1 Garand
Next is 1943 Mosin Nagant M44
Then 1943 Mk IV Lee Enfield
Then 1941 Mauser 98K
And Finally 1944 Arisika Type 99
Shooting and owning each for real, tells you allot about each country. Hands down, the one rifle you would want to carry into for real no bs Combat is the M1. I love the M-14, I carried one for real in the Military (US Navy kept them into the late 80's), I have an M1A but, prefer the M1. The true M-14 (which you can never buy since its a Class 3) is uncontrolable in full auto. M4 or any AR-15/M-16 Family is not realibile and 5.56 is too light. For a no-shi@ Zombie Apocalypse gun it would be a toss up between the M1 and AK-47
