Machine Gun Preacher
 

I don't see it listed in the imfdb article, but I could swear there was a scene where someone had what appeared to be an AK-74 judging from the muzzle brake. Anyone who has seen this movie noticed this?

The page was made from the trailer, so it's incomplete. You can finish it if you like.

I'll have to get the movie from Netflix again and check it out. I'm not sure what software I can use to get screen captures.

The muzzle brake isn't necessarily a defining feature.

Ben41's user page is an excellent guide to getting screencaps. The programs involved are free and portable if necessary.

The "AK-74" was probably a Vektor R5 modified to look like one (since the movie was filmed in South Africa). One such gun was featured in Strike Back Project Dawn:

And heavily in District 9
