This is a 40mb pack containing the exemplars from my "I don't care enough to upload these and I don't use them anymore" folder. It includes many things, primarily guns (Especially automatics) but also some physics sounds.
In summary, there are:
27 Sounds for LMGs of some sort, like the M249, PKM or M60
37 Sounds for Assault Rifles, like the IMI Tavor, AK-74 or M4A1
13 Sounds for SMGs, like the TDI Vector or MP5
30 Miscellaneous Physics sounds, like bullet hits, wooden shit breaking and some stuff for a Riot Shield
9 Sounds for .44 and .357 Revolvers
17 Sounds for Sniper Rifles, ranging from 7.62s to completely hypothetical 30x150mm AMRs (Mostly 7.62s, tho)
22 Sounds for shotguns, about half of which are pumps.
And some other stuff.
I make no guarantee for quality. Some are just plain not great, others have a good kick to them but use unclean sources, etc. Quantity over quality for this one.
