When I think of the quadrant sight we had on the M203, I am so jealous. It was as cumbersome to use as to read about it.

M203 40mm Grenade Launcher


The launcher is capable of firing a variety of low velocity 40mm ammunition. The launcher also has a quadrant sight which may be attached to the host rifle's carrying handle and is used when precision is required out to the maximum effective range of the weapon. The M203A1 has a shorter barrel and a quick release mechanism to facilitate rapidly attaching and detaching the weapon. The M203A1 was primarily intended for use on the M4 carbine and similar short barrel members of the M16 family.

The standard leaf sight is a folding, adjustable open ladder design that permits rapid firing with out manipulation. The leaf sight uses the front sight post of the M16 rifle or M4 carbine as the front aiming post. The leaf sight base is permanently attached to the rifle hand guard by two mounting screws. The leaf sight base serves to protect the leaf sight from damage when the leaf is not being used and is in the down position. The leaf sight mount is attached to the sight base and is used to rise and lower the sight leaf blade. The leaf sight is graduated in 50-meter increments from 50 to 250 meters.

The quadrant sight assembly mounts on the left side of the carrying handle of the M16 rifle. The quadrant sight arm serves a dual purpose. It mounts the sight aperture arm (which holds the sight aperture) and the sight post arm (which holds the front sight post). The following procedure is used to fire with the quadrant sight. The front sight post can be used to make minor adjustments in elevation when zeroing the launcher. For elevation adjustments, turn the adjustment screw on the sight post clockwise to decrease elevation and counterclockwise to increase elevation. One full turn on the adjustment screw will move the impact of the projectile 5 meters at a range of 200 meters. The rear sight aperture can be adjusted for minor changes in deflection when zeroing the launcher. For windage adjustment, press the rear sight retainer and move the aperture away from the barrel to move the impact to the left. One notch on the rear aperture will move the impact of the projectile 1 and 1/2 meters at a range of 200 meters.

The AUG, a bullpup 5.56mm assault rifle, is a selective fire weapon with a conventional gas piston operated action. he primary variant of the rifle, designated the AUG A1, consists of six main assemblies: the barrel, receiver with integrated telescopic sight, bolt and carrier, trigger mechanism, stock and magazine. Integrated with the receiver casting is a fixed carry handle that contains a 1.5x telescopic sight made by Swarovski Optik.

Operating mechanism
The rotating bolt features 7 radial locking lugs and is unlocked by means of a pin on the bolt body and a recessed camming guide machined into the bolt carrier. The bolt carrier itself is guided by two guide rods brazed to it and these rods run inside steel bearings in the receiver. The guide rods are hollow and contain the return springs. The bolt also contains a claw extractor that forms the eighth locking lug and a spring-loaded "bump"-type casing ejector.
The gas cylinder is offset to the right side of the barrel and works with one of the two guide rods. The AUG uses a short-stroke piston system where the right guide rod serves as the action rod, transmitting the rearward motion of the gas-driven piston to the bolt carrier. The left-hand rod provides retracting handle pressure when connected by the forward assist and can also be used to remove fouling in the gas cylinder by utilizing the left-hand guide rod as a reamer. The firearm uses a 3-position gas valve. The first setting, marked with a small dot, is used for normal operation. The second setting, illustrated with a large dot, indicates fouled conditions. The third, "GR" closed position is used to launch rifle grenades (of the non-bullet trap type).
The AUG is hammer-fired and the firing mechanism is contained in the rear of the stock, near the butt, covered by a synthetic rubber shoulder plate. The hammer group is made entirely of plastics except for the springs and pins and is contained in an open-topped plastic box which lies between the magazine and the buttplate. During firing the recoiling bolt group travels over the top of it, resetting the hammer. Since the trigger is located some distance away, it transmits its energy through a sear lever which passes by the side of the magazine. The firing pin is operated by a plastic hammer under pressure from a coil spring.

The Truth about "Assault Weapons"



[video=youtube_share;YjM9fcEzSJ0]http://youtu.be/YjM9fcEzSJ0[/video]

A police officer explains the differences between a fully-automatic "assault" rifle, a common semi-automatic rifle, and a semi-automatic hunting rifle. He explains how the media usually get's it wrong when reporting on tragedies involving mass-shootings by indiscriminately throwing around the term "assault rifle".

For reference sake, when the officer refers to "Stockton CA" early in the video he is referring to a mass-shooting that occurred at an elementary school in 1989 where a lone assailant opened fire with an AK variant, wounding dozens and killing several children.

No matter what side of the gun debate you are on, this is an educational video that will at least ensure you use the correct terminology, and avoid over-sensationalizing tragedies that gain national media attention.

Robinson XCR Rifile

It's one of the first new assault weapons that was designed to utilize multiple calibers with minimal adjustments. It boasts no loss of zero from barrel removal and replacement, requires only the exchange of the barrel and bolt to swapcalibers between 5.56 Nato, 6.8 SPC and the ever common AK-47 round, the 7.62x39mm. It accepts AR-15, M16 and AK-47 magazines. It is designed with ambidextrous safety switch and bolt release and a nonreciprocating charging handle that has been placed on the left side of the weapon for left hand operation leaving the trigger hand in place and the rifle ready for engagement during charging and more important, immediately after.
