“What In The World Most Deadly And Efficient Assault RifleWhat In The World Most Deadly And Efficient Assault Rifle”?
That’s simple, the one that’s easy and cheap to mass produce, one that’s easy to maintain in the filed and one that’s reliably cycles a
cartridge that makes the best compromise between all of the variables involved.
That was actually achieved back in 1911 with the world’s first true assault rifle, Fedorov Avtomat.
Short recoil operated, 600 rounds per minute, firing a 6.5mm Fedorov intermediate cartridge from a 25 round mag. The cartridge held an 8.5 gram
projectile which was propelled at 860 meters per second and generated 3140 Joules of muzzle energy, which is actually the sweet spot for automatic
fire. Low impulse, low recoil, high velocity round with good energy, flat trajectory and great penetration.
Currently the deadliest AR is the AEK-971.
It is the world best handling AR in full auto fire, which is the primary job of the AR.
Key feature of the AEK971 is gas driven, balanced action with rotating bolt barrel locking. Balancing mean that AEK971 gas drive has two gas
chambers and two gas pistons. First gas piston is linked wia gas rod to the bolt carrier an moves as usual. Second gas piston is linked to the
balancing msteel weight and moves in opposite (to main gas piston) direction. This design is implemented to eliminate 3 of 4 total impulces of the
movement that affect rifle during the full-auto fire. 1st impulse rifle received when bullet moves along the barrel - this is recoil itself. Second
impulse rifle received when heavy bolt carrier/bolt group moves along the receiver back and forth. Third impulse is received when bolt carrier/bolt
group stops in the rear position and fourth - when this group stops in forward position after new cartridge is chambered. Synchronous and opposite
movement of the balancing weight eliminates all except the recoil impulse, so rifle becomes far more stable during full-auto fire.
M-16A2 is NOT an AR, simply because it’s not capable of full auto, and is limited to 3 round bursts.
M4 is by far NOT an AR, same 3-round burst and because its barrel is too short to generate the muzzle energy required by true ARs.
From the very beginning M16 family was created as an automatic RIFLE, which is clearly apparent to anybody who actually fired it.
Its selector switch is on the left side. 1st position is SAFE, 2nd semi-auto, and 3rd full auto or 3-round burst.
True assault rifles switch from SAFE immediately to FULL auto, and then to semi-auto.
For example, the very first AK had its selector switch on the RIGHT side, 1st position was SAFE, while at the same time the selector acted as a dust
cover thus protecting the weapon from contamination, 2nd position was FULL auto, 3rd semi-auto.
M16 did not have a dust cover, which resulted in chamber contamination and imminent stoppages, mainly from the bolt not fully closing.
M16A1 was modified with a spring loaded dust cover and a forward assist which allowed a shooter to forcibly close the bolt by pounding on the forward
assist with the palm of his hand.
Still full auto resulted in stoppages do to inherently weak gas system which is to this day unable to handle rapid firing and overheats, so starting
with A2 model full auto was replaced by a 3-round burst trigger group.
Best Western ARs are HK G36, SIG SG-550 family, FN FNC and FN SCAR.
Steyr Stg.77 AUG is a great bullpup, but bullpups are not for everybody.
