My experience with two rear sights on a changeable rear sight

 For a changeable rear sight. which can be changed almost instantly. 

Personal.

Rear sight which is rectangle with a small rectangle groove, and round and | on the front.

-I use this one with normal light.

-Better accuracy maybe.

Round rear sight, quit big. And a round front sight, with a |

-I use this one with lower amounts of light.

-Easier to aim and faster. More to see, and more light comes trough.

Assault rifle or other rifle as an improvised weapon

Assault rifle or other rifle as an improvised weapon.

Two hands.

Some are experimental to try.

Forwards thrusts

Rear stock attacks, forwards

Side and corner of the barrel attacks, forwards

Rear stock bashes or battering rams, if possible, forwards or forwards from a sideways posture.

Two hands forwards at the same time, rifle or assault rifle held level or angled, two hands both thrust

forwards, hands are basicly kept synchronical

Grabbing the rear stock or the barrel and sideways or downward swings with the assault rifle.

Downward thrusts. Grabbed at the barrel. Or grabbed at the rear stock and one hand on the end of the rear stock.

A special firearm (assualt rifle or sniper for example) scope or scope add on for behind cover or in trenches

 A rifle scope or sniper scope. Which has multiple parts or a part which can be fitted on.

A scope or an extra part for the scope, can be done on.

Like, so it's possible to see through the scope, while the gun is on the cover, but

the person is hiding, not being visable, while it's possible to see through the scope

and shoot down enemies.

I've actually seen similar ideas from the WWI and WWII trenches. But they were more primitive.

A scope and a red dot, both on the assault rifle

A scope and a red dot, both on the assault rifle.

-Scope for far away enemies.

-Red dot for close by enemies.

Tilting the assault rifle to change from scope to red dot or from red dot to scope.

With a scope it's hard to shoot 2-3 closer by enemies, because of the searching needed, it's to zoomed in.

And with a red dot it's hard to shoot far away enemies.

Firearms trainings and drills - Two handed and one handed shooting with assualt rifles and more

Two handed shooting.
-Right handed main grip and trigger pull
-Left handed main grip and trigger pull

One handed shooting. When wounded for example. (safety is very important)
-Right hand
-Left hand

It's possible to train all and can be of use. Though it can be most adviced to train mainly train your main way of shooting.
And changing it up sometimes while shooting a single magazine is possible.

With an assualt rifle, when you have a not to wide cover, you can shoot from both sides by changing up your grip, this can be useful or even
important for tactics.
-Putting it against the right shoulder with a right hand trigger pull for shooting from the right side
 and putting it against the left shoulder with a left hand trigger pull for shooting from the left side

Important:
-Right handed shooting: Right eye open and for aiming, left eye closed
-Left handed sooting  : Left eye open and for aiming, right eye closed
Being able to hold one eye open and one eye closed at both sides is a good skill.
-And you can train this for both eyes
