The weapon issued to John Rambo (Sylvester Stallone) by his CIA controllers is a Heckler & Koch MP5A3. He loses the weapon when he is forced to cut away his equipment when his parachute rigging gets caught up during insertion. When he is first seen loading it up, it is fitted with a 3x scope, but when he prepares for the drop, it appears to have been removed. Like many other "MP5A3s" at the time, this gun is actually a chopped and converted Heckler & Koch HK94.
A Vietnamese soldier is seen armed with an H&K HK93 rifle while watching from a tree. It is far more likely to be an HK93 over an HK33 because Stembridge gun rentals had many in stock at the time and they were easier to acquire over the selective fire HK33 variant.
When Co Bao disguises herself as a prostitute to save Rambo, she uses a MAC-10 with a mock-suppressor to fend off the Vietnamese troops. Somehow this film was nominated for a Best Sound Academy Award despite how Rambo's AK spits out rounds at ~650RPM while her MAC-10 fires at ~1200RPM and both guns have the same report in the film.
After his insertion back into Vietnam, Rambo meets up with indigenous agent Co Bao (Julia Nickson-Soul) who is armed with an AKM. Rambo later picks up a few AKMs throughout the film to dispatch several Vietnamese and Russian soldiers. Vietnamese and Russian troops are widely seen armed with AKMs as well. As in most Hollywood movies, the AKMs in the film are all Egyptian Maadi ARM copies of the original Soviet AKM (much like in the film Red Dawn).
One of the Russian soldiers is seen with a genuine AK-47, likely a Poly Tech Legend AK-47 rifle, although this may have to be confirmed due to sketchy time era.
A Vietnamese soldier is seen armed with an Valmet M78 rifle in a tree. It appears to be dressed up like an SVD Dragunov by adding the infamous thumb-hole stock and being fitted with a scope.
This is the chief weapon Rambo fires in the film. It is first seen being fired by a Russian door gunner after their UH-1 dropped napalm on the waterfall where Rambo was fleeing. When Rambo flies the POWs out of the prison camp in a Bell UH-1 Huey (possibly a Vietnamese one (due to the VPA making use of former ARVN weapons and vehicles after the Fall of Saigon in 1975) on loan to the Soviets), he lands the chopper and picks up the M60E3 machine gun from the chopper door. He later empties it in the command center to destroy all the high tech equipment and scare Marshall Murdock (Charles Napier) for betraying him.
CIA operator Banks (Andy Wood) mans the M60 mounted on the Huey sent to pick up Rambo. He is seen providing covering fire with it in the rescue mission to retrieve Rambo.
An opposing Vietnamese gunboat begins to blow apart the gunboat Rambo is on with dual mounted Browning M3 anti-aircraft .50 caliber guns noted by their perferated barrel shrouds.
When Rambo and the POWs escape the camp in their captured UH-1, Lt. Col. Podovsky (Steven Berkoff) chases them down in his Mil Mi-24 Hind-D (which in reality was a modified French Aerospatiale Puma). The door gunners on his Hind begin firing at Rambo with their M60D which are mocked up to resemble the aircraft model DShK heavy machine gun by being fitted with a semi-similair muzzle break and spade grips.
Mounted on the right side of the UH-1 is a GE M134 Minigun which is electrically fired by Rambo at the controls when he strafes the POW camp and is then manned by one of the POWs, who manages to kill a Russian Hind door gunner with it.
Seen as the sidearms of all the Vietnamese soldiers is the Yugoslavian M57, the Yugo copy of the Russian Tokarev TT-33, which was in short supply at the time. The Chinese Norinco Type 54 would be more accurate for them to use for the film, which would be noted by a frame mounted safety switch (which these all lack).
CIA operator Banks (Andy Wood) pulls out a SIG-Sauer P226 pistol and holds it to Colonel Trautman (Richard Crenna) when he tries to stop the chopper from leaving Rambo. It is noted as a P226 by its double stack creases on the frame. The P226 was a brand-new pistol on the American firearms market in 1984-85, when the film was made, so it is likely that Rambo: First Blood Part II is the very first movie to feature this gun (it was previously stated on IMFDB's RoboCop page that RoboCop was likely the first movie to feature a P226).
A Vietnamese pirate can be seen wielding a Remington 870 shotgun with a wooden forend, extended magazine tube, and folding stock. Rambo (Sylvester Stallone) fires a few rounds at the pirates with the shotgun.
Rambo disposes of an enemy boat by pulling a fake RPG-7 (which appears like the armorers of Red Dawn, who did this film, brought it with them from that film, albeit more convincingly dressed up) out from under a compartment in the gun boat.
When Rambo crashes his chopper, Podovsky's Hind flies over to confirm the crash. Rambo plays dead until the Hind is in range, then fires (with the safety on) an M72 LAW launcher through the windshield and blows them up. It should be noted that the powerful back blast of the LAW would have likely killed or wounded all the POWs in the back of the chopper.
While not a gun, we let Rambo's knife stay because, well, he's Rambo and his knife completes him. Like in the original First Blood, Knifesmith Jimmy Lile was asked by Stallone to design a knife for the movie.
Another non-firearm Rambo gets away with, his Hoyt Archery compound bow which has been well know as the "Torque Bow" because of the high explosive arrow tips he looses from it.
When escaping the Vietnamese camp, Rambo grabs a bag of M67 "Baseball" Grenades and uses them against the soldiers.

M29 81mm Mortar
When Rambo, Co Bao, and the POW run throught the rice paddy field, Vietnamese soldiers drop M29 81mm Mortars across the field at them but don't score a hit.
