SureFire A2 Aviator warranty still valid?

[yazkaz]

Just to get some clarification: Will the A2L tailcap work on the A2 Aviator? I don't have an A2L, so I can't check this out.

Yes it does, 100% compatible, except the dot indicator on the A2L tailcap host does not line up with the A2's tail nub indicator for constant low on.
To activate constant low on you'll need to turn past the dot/nub alignment by a quarter turn.
