AR-15 Rifle Test Quiz!
AR-15 Rifle Test Quiz
I am semi-retired and I am taking a self-passed and self-taught Firearms Armorers course. I have covered over 25 different firearms in this course and now I am on the AR-15 Rifle course which is my last firearm in the Armorers course.
I hope to become a part-time light Gunsmith in the future. I am now working part-time with a Gunsmith that has over 40 years’ experience. I have my CHL and my FFL.
There are many questions covering this firearm and I have answered them to the best of my ability but during my study and research I am having some problems with these quiz questions. Either I am not sure of the correct answer or I have conflicting answers.
Can you help me determine the correct answers for these quiz questions? Please correct my wrong answers!
Thanks for your help.

19 = Action spring (the RE is the buffer tube)
22 = true - the carrier hits the metal piece on the inside of the dust cover when it moves forward or backward
23 = false - the safties are much different, the auto safety has grooves to operate the leg on the autosear.
25 = c. pull it re arward
26 = a - The safety/selector detent and spring are under the pistol grip.
31 = true - it's a roll pin on every AR I've ever owned.

Negative, Ghostrider... the RE holds the buffer retainer pin and retainer pin spring.... you know... when you thread the RE into the lower and you have to push the retaining pin down until the RE just rests over the edge of the Retainer pin???

33. The barrel and the gas tube come off of the receiver all in one piece - True or False?
The way I am reading this question, they are asking if the barrel and gas tube come off the "upper" receiver in one piece. If thats the case, then the answer is False

For the most part, I think the above is pretty well laid out, and should be a good judge of working knowledge of the weapon system. This is better written than most AR15/ M16 armorer tests I've taken.

I saw that you have posted different questions from thisu test on a different AR site.... just interested if you could email or post the rest of the questions? Ive enjoyed testing myself and finding my weak points on the AR platform.

The hardest part about writing any test is in doing so without ambiguity. Having a preceding knowledge on a given topic makes this somewhat hard to do as the question / answer may be clear to you but not so for those learning the topic. Overall, this was the only question that made me confused about what was being asked. I would agree with Stick that it is a fairly good exercise.

No worries. I didn't mean that comment to say you were.
I work for the North American subsidiary of a French hydraulics company. We have some technical evaluations and "tests" that we take on a yearly basis or so and some of the questions can't even be answered because of the language translation ambiguity. It really opened my eyes up to the difficulty of creating fair questions to be properly answered and judged.Hatter
