I’ve got a couple of metric FALs, Austrian and Brazilian, that take the same (long type A?) gas plugs. Of course, the parts companies are always goading me to buy extras (“because your SOL if you lose your gas plug”).
So, over the years I’ve accumulated several well worn surplus gas plugs (forgetting that I already had a couple socked away): among the ones that fit, some have levers, some do not, but they seem to be identical in size — except for Israeli gas plugs, which are useless because they don’t fit in the gas block (flanges too big).
The other day, I ordered a refinished gas plug from Apex, but it turned out to be 1/4” shorter than my others (type B?)
Is this Type B gas plug useable in a Type A gas block?
How many different varieties of gas plug are there for the FAL?
Thanks!
