|quotetext=Although While it's not nearly as well-known as the [[RPK-74]], if you're looking for a machine gun chambered in [[5.45x39mm]], the Poplin is effectively your only belt-fed option. Although visually and ergonomically similar to the RPK-74, the PU-21 is unrelated to the Kalashnikov action. It is more complex and has no provisions for accessories out of the box, but it does offer a 200-round belt that simply outmatches the firepower of any other 5.45mm platform. If you're after volume of fire first and foremost, the Poplin will give competitors like the [[M249]] and the [[IMI Negev|Negev]] a run for their money.

=== PU-21 M Poplin Modernized ===''Okay, I know what's up. You bought this thinking to yourself you'll make all the RPK fans jealous. Then you saw all the cool stuff they attached on theirs. Suppressors! Red dot sights! Scopes! Muzzle brakes!... And here you are, with your plain-jane machine gun and iron sights. It's time to fix this and bring the PU-21 Poplin in line with the cool kids. This package also replaces all the wood furniture with slick black plastic. The handguard now features a pair of accessory rails, and the fixed stock is replaced with a folding model patterned after the AK-100 series.''
