AR-15 vs M1A (and MAS 46/59) mud and sand tests

[Evil Tim]

I have a feeling that rail over the action of the M1A wasn't helping much.

Then again, this is why during WW2 they issued soldiers with gigantic condoms to put over their rifles to protect them from this kind of thing, leading to that almost-certainly-untrue story about Winston Churchill ordering for them to be labelled "medium" to frighten the Germans.
