Essential Replacement Parts for my Rifles (to go)? (FAL, AK, AR)

[ZombiesAhead]

Hello,
I've got a few rifles I would consider grabbing "just in case" although I'm not sure which one. For each of these I keep plenty of rounds, magazines, small cleaning kits, mag-holders, etc.

I also would like to get the few essential replacement parts for each gun (just the very important - firing pin, recoil spring, gas rings, whatever is known to fail and can fit in a small case).

So what do you recommend for each rifle?

1. Romanian WASR GP-10 (7.62x39, PK-AS red-dot and irons, folding or fixed stock, sling)

2. DSA metric FAL (7.62x51, irons, 21", fixed stock, bipod, sling)

3. Bushmaster AR-15 (5.56x45, irons, 16", fixed stock, sling)

Go to that page and read the "9 hour 10,000 round torture test" article.

In that entire test they had four stoppages, and the only things that broke were the foregrip pin and the gas plug - both prototype designs.

So gas plug and grip pin should probably be on your list for the FAL

How about this for the AR?:
extractor, 2 extractor springs, 2 extractor spring insert, disconnector, gas ring set, extractor pivot pin, firing pin, 2 firing pin retaining pins, cam pin and spring package of 6 springs.

For the AK?:
recoil spring, firing pin, extractor, extractor spring, trigger/hammer,spring and disconnector spring

Oh, here's another idea: PM El Tejon, he seems to be pretty good at breaking guns, he could probably give you some good advice.
