Yeah. I do have some spare parts on hand even for the AK.
I amended my earlier post to reflect that I was talking about ARs, since that is what this thread is about.
Without turning this into an AK vs AR thread - I want to be clear, my decision has nothing to do with the belief that an AR needs spare parts and an AK does not in order to be run hard.
Simply put, I have quite a few ARs. I have only one AK type - an Arsenal SAM7R.
The ARs accompany me daily at work, and are what I take to training. I keep spare parts because I may need them to continue using the rifle to complete my task. I may have spent a thousand dollars or more on tuition, travel, ammo, food, etc.. to take a carbine class. I don’t want to waste that because my gas rings shit the bed or my firing pin broke. Hell, I bring 2 rifles to every class I attend just in case I can’t fix an issue with the pets I have on hand. It’s cheap insurance to insure my investment in quality training. I also teach AR classes. Pretty bad to have your gun go down while teaching and not have the parts to get it running. It’s also a nice bonus to be able to get student’s guns running if they have a problem.
The AK, on the other hand, is a range toy. I have never taken a class with it. It is for fun and familiarization of others. If it breaks, it breaks. I put it away and drive home or grab another gun. If I was to spend money on an AK class, I would definitely have spare parts on hand to insure my investment in the training.
I should also note that I am a big believer in preventative maintenance. I keep a log and stay on top of my carbines. In all the classes I have taken and training I have conducted, I have had one instance where my rifle was acting up and I needed my kit to replace a part. I was using a full auto gun and my action spring went - I had many thousands of rounds through that gun.The gun started running sluggish, exhibited weak ejection, and it just felt weird under recoil. Luckily, I had a spare action spring and was able to swap it out and drive on.
On the other hand, I have reached into my emergency parts kits many times to give fellow shooters parts to get their rifles running. Gas rings, firing pin retainer pins, etc... Hell, I gave one guy a set of KNS Anti-rotation pins to fix his hammer and trigger pins walking out on an out-of-spec lower so he could finish a 3 day carbine class in Virginia. I’ve also provided my spare carbine to quite a few shooters when their guns went down hard, in order to let them finish the class they spent so much money to attend.
Keep spare parts on hand. They may make the difference between an enjoyable learning experience and an exercise in frustration and wasted money.
