An excellent value for the money, the Mossberg 500 series has seen massive acceptance with sportsmen all over the world. But, these shotguns do have a few problems that this course will help you to solve inexpensively. Also numerous tricks and techniques are provided to insure reliable operation. Just the assembly and cleaning portion of this video course will save you $30-40. A rare factory cutaway is used to clearly demonstrate the inner workings. If you want the quick course on how to get the Mossberg 500 Shotgun apart, back together, and operating as intended, then this course is for you (if you want the long course, look into our basic 108 hour Professional Gunsmith course).

Among the items covered are:

Bob shares his knowledge of the history of Mossberg firearms and its founder, Oscar Mossberg
While working for Iver Johnson, Oscar Mossberg invented the transfer bar, which is still used in many firearms today
Oscar worked for different firearms manufacturers in America, until he and his partner made a four-barreled .22-caliber firearm. This was the gun that was first manufactured by him and his sons under the name O.F. Mossberg & Sons
After manufacturing several models of firearms, they produced the first model of the Mossberg 500 in the early 1960s. Unlike many other firearms manufacturers, they continued to make the Mossberg 500 better and better through incremental design improvements, a process culminating with the excellent shotgun that they manufacture today
