Kitted.gg reads every build on this page directly from the gunsmith screen in tracked streamers' Twitch and YouTube clips — no manual guides, no lobby-API sampling. When a streamer swaps an attachment, the change lands here automatically and the confirmation dates update. That makes this page a live record of what full-time Warzone players actually choose on the PU-21 (also written PU 21), not a one-time editorial pick.
No streamer Kitted tracks currently runs the PU-21. The meta picks right now are MK.78, MXR-17, X9 Maverick.
