Talon Company mercs often carry these weapons at higher levels or difficulty settings. Fort Bannister has frequently-respawning mercenaries with this weapon.
Flak 'N Shrapnel's in Rivet City usually will start out with two of the rifles, and a third can be found in their room on the upper deck (Lockpick difficulty: Average).
One is on a shelf by the door to the Rivet City armory.
One in the Taft Tunnel along with a full Chinese uniform.
One in the Museum of Dave found during the tour on the wall beside a stop sign and a cattle skull.
Rewards[]
Typical store items before and after giving Pronto the rifles
Pronto's shop will have a better inventory and he will also get around 400 caps instead of around 150 (see picture) to barter with. His store is turned into a "typical good gun and ammunition store," of which there already are several in the game, with an additional 20% discount.
Notes[]
Mama Dolce's factory is full of Chinese remnant soldiers and nearly all carry this weapon. One should be able to obtain most (if not all) of them here, making the hunt very short.
If one has begun this quest and wishes to complete it, do not become hostile with anyone in Paradise Falls. While the doctor will still offer services, Pronto does become hostile towards the player character, making it impossible to complete the quest.
Pronto does not care about the condition of the rifles, so repairs are not necessary.
After one has given him the 20 Chinese assault rifles, they have to wait at least 24 hours before his inventory improves.
Pronto will not accept the Xuanlong assault rifle, so player characters using the weapon need not worry about accidentally giving it away.

↑Fallout 3 Official Game Guide Collector's Edition p.324: "FREEFORM QUEST: ECONOMICS OF VIOLENCE When you search Pronto’s tradeable items in Lock and Load, the selection is poor. The Slavers only trade him the useless crap they no longer have a use for. If you ask how you can help, he gives you the Note from Pronto and asks you to collect 20 Chinese Assault Rifles and bring them back to him. If you return 24 hours later, Pronto’s inventory is a whole lot more impressive! The variety of items to sell improves greatly. * Note from Pronto" (Fallout 3 Game of the Year Edition Tour of the Capital Wasteland)
