How the class works:
In lecture, we will study the various firearms and/or systems involved. To
reinforce what we have studied, assignments will be made involving repair,
refinishing, and/or modifications to the studied firearm parts.
To simulate real life situations, there will be due dates on all assignments.
The assignments will approximate problems in the field. Many times the assignments
will force you to think, i.e. I may assign the design and fabrication of a tool or
parts. I will tell you what it must do, and the tool or part must be made to work.
Everyone starts off with an “A” and everyone is expected to get an “A” for a final grade.
This is a potentially dangerous profession, so you must do the assignments to industry
standards or better.
- Everyone must have a set of finished notes by the last day of class. If they are on paper, they must be typed or written very legibly in ink, in a binder or folder, and have line drawings of systems for clarity when needed. They can also be audio, video, or on a computer disk, but if they are, they must have an index. They must also contain most of what was covered in class. If they possess all the mentioned criteria they are “A” notes. If they are missing information, inbound, or electronic with no index, your grade maybe lowered.
- Your projects must be completed in order to be graded. They will be graded on accuracy, appearance and finish.
A note on notes:
They must be good and permanent- NO PENCIL NOTES. You can get around this note
requirement by obtaining the AGI professional series course on the subject, i.e.
the shotgun course for any of the shot gun classes etc. Remember, bad notes and
your grade will suffer.
Method of Evaluation:
Grading in this course will be based on the following:
Class Participation and Attendance: 10%
Classroom notes: 20%
Classroom projects: 70%
90-100% = A
80-89% = B
70-79% = C
60-69% = D
below 60% = F
Incompletes and etc.:
Incompletes are at the discretion of the instructor.
NO LIVE AMMUNITION IN CLASS:
NO! NO! NO! If you need ammo to test fire a firearm, you turn it in to an
instructor UPON ENTERING THE CLASSROOM. Failure to do so will result in your
dismissal from the course.
