This is an in-game realization of the model posted by Wikinger_germ.

There are two files available. A 5.56 version compatible with the stock game, and a CALIBR version in 7.62 x 39. The CALIBR version has slightly better damage stats. (Note that you must have the CALIBR mod to use this version). http://www.fallout3nexus.com/downloads/file.php?id=3447

I used the Xuanlong Assault Rifle as the base, but set the spread a bit lower to make it more accurate (This gun IS in almost mint condition).

Individual weapons are available for sale by Flack & Shrapnel, Moira Brown, and Chief Gustavo.

CALIBR Version: Respawning 7.62 x 39 ammo is available in 100rd increments from Flack & Shrapnel, Moira Brown, Chief Gustavo, Tulip, and Lucky Harith.

EDIT : I have added and optional ESP for the The CALIBR Version. (You have to have installed the MAIN calibr version first for this file to work). Use this file ONLY if you need LOTS of extra ammo. This file adds additional respawning 7.62 x 39 Ammo Boxes added to Megaton - Players Home (next to front door locker), Rivet City Market (next to the workbench), and Tenpenny Tower (next to Gustavo's lockers in the courtyard). Simply download the new ESP (AKM Assault Rifle - CALIBR Ammo Respawns), and overwrite the old ESP in your data folder...

Please let me know if you notice any problems, etc..
