This replaces the old thread. As always, contributions and corrections are welcome.

For a broader list of DOD acronyms, abbreviations and terms, see Ghillie suit.

For acronyms and abbreviations in general, see this or this.

Here is the list of acronyms and abbreviations specific to AR-15 and AR15:

@ - When prefixed to a member's name, means that the following comment is directed "at" or to that member.
. - Used to add a post without typing anything, means "+1 to my post count, I have no new comment" or the same thing as BTT. Also sometimes left behind as a placeholder when someone deletes the content from a post or as a quick post to tag a thread.
+1 - When used with a quote, means the same thing as "Ditto" or "I agree". When used in the EE feedback forum, means a good experience with either a buyer or seller. When just posted with no reference, it means "+1 to my post count, I have no new comment" or the same thing as BTT...
-1 - When used in the EE feedback forum, means a bad experience with either a buyer or seller.
87 - A nonsensical answer to nonsensical numerical questions. For example, someone might ask "How many magazines should I buy?" There is no meaningful answer to this question because it varies according to each persons' unique circumstances, so the canned answer becomes "87". Originated by markm, presumably because he felt it a waste of time to answer such questions, it has since taken on a life of its own and is used by others who think it makes a funny in-joke. The number 87 is also associated with several other meanings in general usage.
88 - Short hand for a neo-Nazi or, more loosely, any white supremacist. Derived from "H" being the 8'th letter in the alphabet, and HH being an abbreviation for "Heil Hitler". The number 88 is also associated with several other meanings in general usage.
