The following guns were used in the film Outpost:
Pistols
Beretta 92FS Centurion
Prior (Richard Brake) uses a Beretta 92FS Centurion to shoot "The Breather" (AKA The SS Officer).
Beretta 92 Centurion - 9x19mm

Bruni 8mm blank-firing replicas
Bruni 8mm blank-firing replicas stand in for M1911-type pistols.
Cotter searches the compound with sidearm drawn.
DC chambers a round into his M1911. This would mean that he A) carries an M1911 in condition 3 in a combat situation, and B) he actually carries two sidearms, since he had the SIG-Sauer P239 as well. Also, note his finger on the trigger even though he's supposed to be Royal Marine.
SIG-Sauer P239
DC (Ray Stevenson) hands his SIG-Sauer P239 to Hunt (Julian Wadham).

Rifles
AK-47
Mercenary Taktarov (Brett Fancy) carries a AK-47.
Poly Technologies AK-47 - 7.62x39mm. This is the commercial clone of the original Type III AK-47 and is the most used in American films and shows when showing the milled receiver AK-47
Tak fires at the source of incoming fire.
AKM
Mercenary Cotter (Enoch Frost) carries an AKM.

FAMAS
One of the men entering the compound in the end is carrying a FAMAS.
FAMAS F1 - 5.56x45mm NATO
If you look VERY closely, you can see the faint outline of a FAMAS to the left of the light.
H&K G36C
Mercenaries DC (Ray Stevenson) and Jordan (Paul Blair) use Heckler & Koch G36C assault rifles.
Heckler & Koch G36C 5.56mm
DC aims his G36C. It's odd that Ray Stevenson handles firearms so well in some scenes and so poorly in others. (See above.)
Jordan with his G36C. The sound mixers used different sound effects for Jordan's G36C and DC's G36C, even though they're the same type of rifle.
Mauser K98K
The Germans are armed with Mauser Karabiner 98k rifles.
Karabiner 98k - 7.92x57mm
Norinco Type 56
Mercenaries Prior (Richard Brake), McKay (Michael Smiley), and Voyteche (Julian Rivett) all carry folding-stock Norinco Type 56-1 rifles.
Norinco Type 56-1 - 7.62x39mm

Blue track jackets must be very popular in the former Yugoslavia.
Submachine Guns
MP40
German soldiers carry MP40s in the background and in the archival footage.
When a bullet to the head isn't enough...

Heckler & Koch FABARM FP6
