The Browning Hi-Power is the usual sidearm carried by Col. John "Hannibal" Smith (George Peppard) in Season 1. The pistol is notably in "Black Day at Bad Rock" (S1E06).
A Beretta M951 is briefly seen in the hands of a skyjacker, who is swiftly disarmed by "Howling Mad" Murdock (Dwight Schultz) in "The Beast from the Belly of a Boeing" (S1E13).
The Star Model B is seen on few occasions during Season 1. A suppressed Star Model B is seen in the hands of Hannibal (George Peppard) during "The Rabbit Who Ate Las Vegas" (S1E07).
The Colt Detective Special revolver is another firearm seen in Season 1. Police Inspector Ed Maloney (Norman Alden) checks his DS in "A Small and Deadly War" (S1E05).
The Smith & Wesson Model 10 is another firearm seen in Season 1. Amy Allen (Melinda Culea) takes a revolver with a 3" barrel from a security guard in "The Beast From The Belly Of A Boeing" (S1E13).
Used in the two-parters "Judgement Day" and "Mexican Slayride". In "The Out-Of-Towners" a thug can be seen firing a Thompson M1928A1 with a drum magazine. As a nice gag, Hannibal is hanging onto a 1930's car with a Thompson with drum magazine and fires on a mafia boss in Season 4's "The Little Town with an Accent".
A MAC-10 mocked up to look like an Uzi with fake Uzi furniture mounted on the barrel and receiver can be seen being used by Murdock (Dwight Schultz). These same Uzi mock-ups can be seen in Raw Deal, The Dogs of War, and also Stripes (they were all built by a company called Special Effects Unlimited, which provided the weapons used in the first two seasons of this show).

Note that he is wearing the ear muffs so the bullet hits on the barrel he is hiding in won't blow his eardrums when he is taking cover. They also show the barrel being lined with 1/4 inch steel sheeting, which explains it being bullet-proof.Error creating thumbnail: File missingAnother mocked up MAC-10 in the hands of Dwight Schultz during "The Rabbit Who Ate Las Vegas".
Ingram Model 6
Members of the A-Team and various bad guys use the Ingram Model 6 in the pilot episode. Possibly the only time that this little known SMG has appeared either on television or in the movies.
The main villain in "The Only Church In Town" is armed with an Armalite AR-18. It can also be seen in "Recipe For Heavy Bread". This weapon, along with the older Armalite AR-10, were often used as stand-ins for the more expensive M16 in television shows and movies.
The M16/SP1 is probably the most high-profile firearm in the first 4 seasons, being used by bad guys and members of the A-Team on dozens of occasions. Most of the M16 SP1s used on the show have been fitted with M16A1 flash hiders, in order to stand in for the newer rifle (though some genuine M16A1s also appeared on the show).
Has its first appearance in "One More Time", Season 1, used by the Rashaad's men. Seen in the hands of one of Salvador's men in Season 2, "The Only Church In Town". It can be identified as the P variant by the plastic stock.
Sheriff Hank Thompson (Ed Lauter) carries an Ithaca 37 shotgun in "Black Day at Bad Rock" (S1E06). It's also seen in the episode mounted in the weapon rack in the sheriff's office along with multiple other shotguns. The bartender in "The Out-Of-Towners" (S1E08) uses an Ithaca 37 with sawed-off stock and barrel. Another Ithaca is carried by Sheriff Jeff Lewis (Burton Gilliam) in "A Nice Place to Visit" (S1E14).
Used only when the script calls for a trained assassin is a Arisaka Type 99 rifle. Specifically, the Type 2 takedown paratrooper variant.

It can be identified as the Type 2 takedown paratrooper by the sling swivel and the receiver. Sporterized versions of the Type 99 are often used when a weapon that can be easily assembled is called for.
Remington 700
In "A Nice Place to Visit" (S1E14), a Remington 700 BDL appears to be the rifle seen in the home of Ray Brenner. The rifle is seen in the hands of Trish Brenner (Joanna Kerns), Amy Allen (Melinda Culea) and Face (Dirk Benedict) in the episode.
The M60 was the regular squad support weapon in the series, almost always used by Hannibal Smith (George Peppard) and rarely by B.A. Baracus (Mr. T) even though he would have been the obvious choice but was more often relegated to using a nickel plated Star Model BM with ivory grips. The M60 is prominently used by Hannibal in Season 1's finale "A Nice Place to Visit" (S1E14), as he retrieves from the trunk of a fallen former Green Beret.
The right hand man of Malavida Valdez (Sergio Calderón) is seen carrying a Vickers-Berthier Mk.1 light machine gun during the Season 1 Pilot episode "Mexican Slayride".
Hannibal (George Peppard) retrieves Mk 2 Hand Grenades from the trunk of Ray Brenner, a fellow Green Beret, in the Season 1 Finale "A Nice Place To Visit".
