Hawkins Police Chief Jim Hopper (David Harbour) once again returns to using the Smith & Wesson Model 66 revolver as his duty weapon in Season 3. Hopper loses the Model 66 in "Chapter 5: The Flayed" where Grigori acquires the revolver.
One of the Soviet security guards appears to use a Makarov PM when cornering the kids in the Starcourt food court. Possible Makarovs are also seen when Robin and Steve are captured in the previous episode
Tokarev TT-33s are used by Soviet security forces and soldiers, often suppressed. Chief Hopper (David Harbour) and Nancy Wheeler (Natalia Dyer) both make use of TT-33s taken from incapacitated Soviets.
Nancy Wheeler (Natalia Dyer) finds a Remington 870 in Chief Hopper's shed and uses it against the Mind Flayer during the assault on Hopper's cabin in "Chapter Seven: The Bite".
Soviet security forces often carry the anachronistic Zastava M92 carbine while guarding shipments at Starcourt Mall, presumably as a stand-in for the contemporary AKS-74U.
Curiously enough, a custom AKMSU appears as Chief Hopper (David Harbour) appropriates one and uses it in the season finale "Chapter Eight: The Battle of Starcourt" (S3E08).
Soviet soldiers are seen armed with Type III AK-47 rifles. This is anachronistic for Soviet soldiers to carry an outdated version of the AK rifle in 1985 as the AK-74 was adopted as the standard rifle.
US Army soldiers carry and use M16A2 rifles in "Chapter Eight: The Battle of Starcourt" (S3E08) as they storm the Soviet base. The rifles appear to have large "Maglite"-style flashlights taped to the handguards. While technically not anachronistic for 1985 in which Season 3 is set in; the M16A2's use by US Army soldiers is unlikely as only the US Marine Corps at the time period had adopted the M16A2 in 1983. The US Army on the other hand did not adopt the M16A2 until 1986, and it did not begin reaching any Army units until 1988. In 1985, US Army soldiers would still be issued with M16A1 rifles with 30 round magazines.

Machine Guns

UH-1H Hueys are seen with M60D Machine Guns on the M23 mount as they arrive at Starcourt Mall in "Chapter Eight The Battle of Starcourt"
