Jeremy Kelley FTT111 Firearms Inspection and Troubleshooting FTT 111 WEEK 2 TROUBLESHOOTING SCENARIOS Purpose: This assignment is designed to help you contextualize the overarching concepts discussed in the course text by cross-referencing them to examples of existing firearms. As you progress through the assignment, you’ll also progress through the thought-process of diagnosing and repairing malfunctions, as well as predicting the need for certain preventative maintenance. Troubleshooting is a process of asking or investigating, and answering, a series of increasingly detailed questions to eliminate possible causes of a malfunction. This worksheet will “walk you through” the investigation required to troubleshoot a firearm. As you move on to more advanced concepts in later weeks, you will begin generating and predicting the questions you need to answer to diagnose a malfunction. Instructions: Read each situational description below and answer the questions in the space provided. Part 1. Customer brings you an H&R Ultra chambered in .223. He says he has had the rifle many years, and recently it has stopped ejecting the casings after he fires it. Safety: 1. How would you safely clear the feed source, chamber, and barrel of ammunition and potential obstructions? Start by pointing in a safe direction. Then I'd have used the release of the magazine to take it out. Then I'd take the gun and rotate it in order to visually or physically confirm that this chamber was free of obstructions. To remove the case, I would use tools such as nose pliers or picks. 2. In addition to clearing the firearm of ammunition and obstructions, is there any other serious damage that you might inspect for prior to moving forward with the troubleshooting process? I would inspect the ejector/extractor looking for damage like wear and tea Initial Inspection and Diagnosis:
1. What action type is the firearm in question? Break-action 2. What is the most likely type of failure (failure to fire, failure to feed, etc.) the customer is describing? If more than one type of failure is equally likely, list them below. Failure to eject 3. What test(s) might you perform to verify the customer’s complaint? Why would you choose this method over others? I would use snap cap to run the action and see if I am able to get the round to eject. 4. How might the various tests you could perform yield different results in this situation? with failure to eject I would say all tests would come out the same. Detailed Assessment: 1. What do you feel would be the leading issue causing this platform to experience the type of failure you identified (i.e. breakage, wear, debris)? Why do you feel this way? either a worn ejector spring or a damaged ejector spring since this is how the firearm would eject 2. If a component were damaged, what component would be most suspect? Why? Ejector spring since the ejector is used to extract the round Post-inspection and repairs 1. Assuming the auto eject assembly was the cause of the malfunction, in a short customer summary, describe the type of failure, what components caused the malfunction, the components you removed/replaced, and the tests that were performed to verify operation: The autoeject mechanism prevented the spent casing from ejecting on its own when breaking the action, resulting in the shell being stuck in the chamber. We replaced the worn assembly and the broken spring. I used snap caps to rotate the action several times after reinstalling the new component in order to make sure that the shells were discharged as intended. 2. List any additional resources you used for research, in the following format: Last name, first name (of author). “Title of Resource”. Publishing organization or name of website. Publication date and or access date, if available. URL. SDI text book Part 2. Customer brings you a Ruger American that she claims, “isn’t loading properly”. Upon further questioning, you discover that she has no problem loading ammunition into the magazine, but that when she closes the bolt, it doesn’t always grab the next round. The customer has only used one brand of ammunition that she can recall. Safety:
1. How would you safely remove/clear the magazine, chamber, and barrel of ammunition and potential obstructions? Then I'd have used the release of the magazine to take it out. Then I'd take the gun and rotate it in order to visually or physically confirm that this chamber was free of obstructions. To remove the case, I would use tools such as nose pliers or picks. Initial Inspection and Diagnosis: 1. What action type is the firearm in question? Bolt-action 2. Is the malfunction likely to be related to operator-error or faulty ammunition? Explain your answer. It might depending on the magazine being seated correctly 3. What test(s) might you perform to verify the customer’s complaint? Why would you choose this method over others? I would try to see if i can seat the magazine, I would then try new magazines to see if it was a over used magazine. Detailed Assessment: 1. Through to your own research, can you find evidence that a failure to feed malfunction is common in Ruger American rifles? If so, what is usually the cause and how might you properly address these issues? No evidence of failure to feed is common 2. Assume that the component you originally suspected was not the culprit of the failure, what other component(s) might you suspect and why? I'd check to see if there's any damage, debris, or just a failure to install correctly, the magazine catch and the latch. Post-inspection and repairs 1. Assuming the magazine spring was the cause of the malfunction, in a short customer summary, describe the type of failure, what components caused the malfunction, the components you removed/replaced, and the tests that were performed to verify operation: The bullet wasn't raised enough to catch the bolt, because of a defective magazine spring. That's going to make it impossible to feed. I used snap caps to cycle through the magazine after installing my spring. Magazine no longer failing to feed. 2. List any additional resources you used for research, in the following format: Last name, first name (of author). “Title of Resource”. Publishing organization or name of website. Publication date and or access date, if available. URL. SDI text book Part 3.
