Livonia police said the men rammed a stolen minivan Thursday morning through a Shooter's Service shop window, west of Detroit.
Police arrested one man fleeing with a load of guns. Two others were caught in a wooded area. Other arrests were made later.
Police said 34 guns taken in the theft were recovered.
The five men — ages 17 to 21 — were arraigned Saturday on weapons, larceny and other charges, and each held on $1 million bonds. The juvenile was turned over to the Wayne County Youth Home.
The group also has been linked to jewelry store break-ins in two other communities.
