What is your spare parts strategy?

So you’ve built or acquired the rifles you think you need for hunting, or personal defense, in the event of a new gun ban, or the always talked about SHTF scenario; Whatever your reasons, you have what you have. The next logical question is what your spare parts strategy is going to be.

Do you simply stock an extra LPK and upper parts kit, or do you take it further? What about barrels or any other parts that may break or wear out? I guess I am asking what your long term view is.

While there is always the possibility of civil unrest or societal collapse, for me the biggest and most ominous threat is a new ban and whatever form or shape that ban presents. Assuming existing weapons are grandfathered in my primary strategy is to slowly build a stock of items that may become unavailable due to a new ban or lack of availability due to unrest. This begins with magazines to individual small parts like springs, detents, etc. As what I think would be immediate needs reach the appropriate levels I will progress to larger parts like maybe a spare stock, BCG, receivers, etc. I think we all get the idea.

My ultimate goal for the AR-15 platform is 6 rifles (4 - 5.56mm and 2 - 6.8mm SPC). My own philosophy is to be as standardized as possible. In other words, all the 5.56mm rifles should ultimately match each other. The 6.8mm SPC rifles should also match each other. While there may be differences in optics or grips… all the other parts should match. The barrels, BCGs, LPKs, triggers, buffer springs, magazines, should all match. My reason for attempting to standardize is for simplicity, economy, interchangeability, and familiarity. This does not mean the rifles will not evolve a little here and there, but let’s face it, we eventually figure out exactly what we want as our foundation and wish we had a couple just like it.

So here is the goal for myself:
1. 5 of each spring
2. 5 of each detent
3. 10 Magpul P-mags per 5.56mm rifle (minimum)
4. 2 extra Magpul Miad Grips
5. 2 extra UBR stocks
6. 1 extra set Troy folding BUIS
7. 1 complete LPK per rifle
8. 1 extra barrel per rifle
9. 1 extra BCG per rifle
10. 2 extra bolts per caliber
11. 2 extra lower receivers
12. 3 extra upper receivers
13. 2 extra charging handles
14. 10 Barrett 6.8 SPC mags for each 6.8mm rifle

This is just off the top of my head and could change. Some may think I am full of prunes. That’s ok. My strategy is my strategy. I have adopted it for my own reasons. If nothing else, any future grandchildren would have some nice weapons and the parts needed to keep them running for a little while. In the case of civil unrest, my philosophy is to head to the country and try to avoid confrontation if at all possible. Protect my family when needed, but don’t go looking for a fight. I personally think large cities will be miserable places in such an event. If I were in one, the goal would be to get out.

What I would like to know is what your strategy for spare parts might be. I would be very interested in reading what the rest of you do or plan to do or wish you could do.

Thanks!
