Description
This is the factory original magazine made specifically for Kel-Tec SU-16 and PLR-16 platforms. It holds 10 rounds of .223 Remington or 5.56 NATO ammunition and maintains a low-profile, flush-fit design that keeps the magazine well within the magazine well without extending below the platform.
Kel-Tec SU-16 / PLR-16 Magazine Build
The magazine combines a polymer body with a stainless steel spring and polymer follower. This construction balances weight savings with durability for field use. The flush-fit design makes it practical for bench rest shooting or prone positions where a compact profile matters. The magazine has been engineered to work with the specific feed geometry of these Kel-Tec platforms, which use a long-stroke piston system rather than direct impingement like standard ARs.
Compatibility and Magazine Function
While the SU-16 and PLR-16 are AR-compatible platforms, users report that these factory magazines work best as the reference point for the firearm. Some owners successfully use AR-15 magazines as alternatives, though results vary depending on magazine type. The factory magazine is a straightforward choice if you want the same magazine that shipped with your rifle or pistol.
Field-Ready Capacity
At 10 rounds, this magazine fits the capacity standard Kel-Tec designed for these rifles. For those seeking higher capacity, both platforms will accept standard AR-15 magazines, giving you flexibility as your needs change.

Frequently Asked Questions
Will this Kel-Tec magazine work with standard AR-15 rifles?
No, this magazine is specifically designed for the Kel-Tec SU-16 and PLR-16 platforms. While these firearms are AR-compatible in terms of accepting AR magazines, the factory Kel-Tec magazine is engineered for the SU-16 and PLR-16's specific feed geometry and won't reliably work in standard AR-15s.
Can I use AR-15 magazines in my SU-16 or PLR-16?
Yes, many owners use standard AR-15 magazines in these platforms. However, magazine performance varies depending on the type and brand. The factory Kel-Tec magazine is the reference point for reliable feeding, so if you experience issues with AR magazines, switching back to the factory magazine is the first troubleshooting step.
What is the flush-fit design good for?
The flush-fit profile means the magazine doesn't extend noticeably below the magazine well, making it ideal for bench rest shooting or prone positions. This compact design keeps your platform low to the surface without magazine protrusion getting in the way.
Is this magazine original factory issue or a replacement magazine?
This is a factory OEM replacement magazine made by Kel-Tec to the same specifications as the magazines that ship with new SU-16 and PLR-16 platforms. It's a spare or replacement magazine, not a third-party clone.
