Are you people fucking retarded?
Do you have any knowledge of these weapons platforms besides memes? to actually prove that AR pattern rifles somehow are
What is your reasoning to replace the AR platform of rifles with slav shit?
You realized that Russia developed the 5.45 cartridge based on witnessing the effectiveness of 5.56 in vietnam? Guess what Russia's standard issue rifle is? AK74m in 5.45.
5.56 and 5.45 are incredibly effective on humans, the fragmentation of 5.56 and tumbling of the 5.45 creates massive tissue damage and breaks and fragments bone.
7.62x39 is not as lethal because it tends to bore a hole through and through, not efficiently transferring it's energy into the target. It excels in
barrier penetration through brush, walls etc because of it's larger weight.
High velocity, small bore cartridges such as 5.56 and 5.45 are much more efficient at piercing armored targets such as plates and bullet resistant glass, especially with m855 from a 20" barrel, but you lose some of the effectiveness because of the steel penetrator.
They also are easier to hit targets at long range because of higher velocity means less leading of targets as well as less bullet drop.
The type of direct impingement uses less parts than any short stroke gas piston. inb4 muh shit were it eats. The carrier key on the bcg functions as a piston would in a short stroke, gas hits the carrier key and pushes the bolt back.
Direct impingement also increases accuracy because of the lack of moving parts.
this isn't fucking 50's soviet russia, multi lug rotating bolts aren't some sort of witch craft
the more locking lugs, the more consistent bolt lock up which increases the accuracy of the rifle. An AR bcg is not complicated unless you are literally retarded.
The m14 action is shit, there is a reason it has been abandoned.
Go look at the heritage of the recent H&K and SIG designs then come back and tell me how shit the AR platfrom is.
Jesus christ educate yourself before you post regurgitate memes from the internet.
not getting into that in this post but TL:DR the goverment armories such as springfield were intentially trying to sabotage the M16 (sucessfully with the AR10 during 50's trials which adopted that piece of shit M14) as well as goverment trying to cheap out on materials,claiming the rifles were self cleaning, not issuing cleaning kits and not consulting Armalite when they decided to make changes to the powder.
