Any idea where, or how, these photos were put together? Gawd I hope they laid some of those rifles down very gently in that pile!
Being an AI nut, I notice them first. In the top picture that big green folding-stock AI AWM appears to be a "real" G22, as it has a number of features (welded-on night vision rail, bent back bolt handle, etc.) that were never made available on civy AWM models (except for the 10 G22 marked packages that were sold into the U.S. and now trade at around $25,000 and up).
"Real" (unissued) G22 package, exactly like what was sold to the Bundeswehr, that sold on GunBroker:
"1998" date mark, and "G22" mark (where it would normally say "AW", "AWM", etc.). That is some museum quality stuff:
The other AI in the top picture has "Badger Ordnance" on the receiver and is clearly an AICS stock (although I bet that is one hell of a good shooter). And is is sitting right on top of the WA2000!!! Please tell me they placed it on that irreplaceable rifle very gently for a staged photo!! ( j/k

I'm sure they did)
In the lower photo, that looks like a "real" AI PSR. Wow, the tan S&B scope is not much of a colour match is it? And then there is an Ultimo-Über rare folding stock L96 (with the green 6x S&B scope and green metal). This must be from some kind of sniper museum.
Standard L96 as supplied to the UK Armed Forces in the 1980s:
