- A quality European target rifle or air gun with multiple sear trigger system: Anschutz, Walther, Diana, Feinwerkbaugh, Häenel, etc.
- The tools to take the trigger system apart-hammer, punches, screw drivers, be sure you have a 3” or 4” crescent wrench, small pliers and screw drivers.
- A light trigger pull gauge-if you have one.
- An audio or video recorder would be very beneficial.
Student Learning Outcome:
At the conclusion of this course each passing student will be able to:
- Adjust a multisear system for a crisp single stage let-off.
- Adjust the same sear system to a light two stage let-off.
- Adjust levers and engagements to make either stage long or short, heavy or light.
- Reassemble and adjust to a light, crisp two stage let-off, a trigger that the installer has disassembled, then seal the trigger.
- Multiple sear trigger function and adjustments
- adjustable level (fulcrum) function adjustments
- positive, negative and neutral let-off
- sear-striker engagement
- striker fall, distance and energy
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.
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
