If they are rusty and dirty enough, I bet they would take them.
I might get enough to buy the L1A1 I've been eyeing.
I have two of those, both by Century Arms. Whatever you do, avoid buying anything made by Century Arms. I had to have the recievers reworked in order to prevent constant feed problems that resulted in stoppage. CA didn't bother to reproduce the feed ramps that lead the bullet into the chamber. CA does not stand behind their product. I had to get the rework done by an independent gunsmith.
