Here is kinda an interesting point guys with the differences of expected use between the M16(AR15) and the M14(M1A)
First let me say an unfair stigma has been placed on the M16 especially since its field use in Vietnam.
They said"unreliable"-----but was NOT THE GUNS FAULT
The Military turned its head delaying changing the main issue causing the reliability issues associated with the M16
Use of incorrect cartridge powder(yep,the powder)Ball Powder---The Ball powder created a lot of powder ash(this ash also got into the weapons chamber)and the majority of action cycle failures were from ash build up within the chamber/Gas cylinder)
Once they smartened up (but still forgot to issue cleaning kits
)Colt Engineers were working on coming up with what they conceived as a solution---a recoil buffering device(internal plurality of masses)which changed the actions cycle rate and finally allowed the use of ball powder.
The AR15/M16 was originally designed with use of IMR powder(IMR powder has a different pressure curve than ball powder)
Once they did that (buffering device)------------WHAM---the M16 is RELIABLE.
And they found this was even more dramatic in the short barreled M16's
Bottom line----Honestly,the AR15/M16 was designed for jungle fighting.In that arena when the reliability issues were solved---it was considered the ultimate killer.(100yds or less) So much so the naming of it(the Black Gun)was so called as when the VC saw a soldier with one they thought
because of how that cartridge tore the person to shreds at impact.
Now with the advances of powder the .223/5.56 has upped the ante.
This range(ultimate killing range)if so desired can be extended out to 150yds etc.
By that I mean when the bullet hits intended target it tumbles all over and throughout wrecking everything in between like Pack Man getting his fill.
Here is the kicker guys(these black guns)handle the higher velocity ammo.
Example-----my Colts shoot Hornady ammo(3400fps)all day long.
The M1/M14 and I believe the Ruger Mini are not built for the hotter ammo.
They also have no advantage in reliability in very adverse conditions.
Only the AK47 has shown some advantage but carrying a bulkier/much less accurate/less effective cartridge the trade off I feel goes to the M16
Most of us(I really doubt)will need over 150yd combat conditions so with that in mind at least in my own humble opinion----
Advantage AR15 )also I am not saying a .223/5.56 will not kill beyond 150yds,just not with Pack Man effect.
However if I have the need for Long distance stuff (my NM M1A)or my SA M1 aint far away either???????
JMHO
