Description
The KELTEC 5.7X28MM SEMI AUTOMATIC 50 ROUNDS 16 BARREL is a lightweight, high-capacity rifle chambered in the modern 5.7x28mm cartridge. It’s a purpose-built platform designed for rapid, low-recoil engagement, offering a substantial 50-round magazine capacity in a package that weighs just 3.48 lbs. This makes it a serious contender for roles demanding high-volume firepower without the bulk of a traditional rifle platform.
When it comes to home defense or tactical training scenarios, volume of fire and controllability matter. The 5.7x28mm round, known for its low recoil and flat trajectory, pairs with a 50-round magazine to provide a decisive advantage. You’re not looking for a plinker; you’re looking for a system that delivers sustained capability. The 16-inch barrel optimizes the cartridge’s velocity, ensuring reliable performance with a variety of 5.7x28mm loads, including Federal American Eagle and FN SS197SR.
- High-Capacity Dominance: A 50-round magazine fundamentally changes your engagement calculus, minimizing reloads under pressure.
- Lightweight Handling: At 3.48 pounds, it maneuvers like a pistol-caliber carbine but delivers rifle-caliber performance.
- Low-Recoil Platform: The 5.7x28mm cartridge allows for fast, accurate follow-up shots, a critical factor in defensive use.

This rifle is for the shooter who understands the tactical niche of the 5.7x28mm round and needs to maximize its potential. It’s for the home defender who values a high round count in a compact, easy-to-handle package. It’s also for the enthusiast who trains with a purpose, where ammo management is a key skill—starting with 50 rounds per mag changes that drill entirely. Priced at $620.99, it represents a specific tool for a specific job.
Pros: The unparalleled 50-round capacity is the headline feature. Combined with the lightweight build and the inherently low-recoil 5.7x28mm round, it offers a unique blend of firepower and controllability. The 16-inch barrel is a practical choice for maneuverability without sacrificing too much velocity. Here’s the thing—it’s a drop-in ready platform that requires no gunsmithing to get into action.
Cons: The 5.7x28mm ammunition, while more available than in years past, is still more expensive and less common than 9mm or 5.56 NATO. The platform’s design is specialized, which may limit aftermarket support compared to ubiquitous AR-15 patterns. You’re investing in a specific ecosystem.
Frequently Asked Questions
Q: Is the 50-round magazine reliable?
A: Keltec engineered this rifle around its high-capacity magazine. While any magazine can be sensitive to maintenance and ammunition quality, the design is built to feed the 5.7x28mm cartridge reliably. Using quality ammo like FN or Federal is recommended for best results.
Q: Can this rifle use magazines from other 5.7x28mm firearms?
A: No, it uses a proprietary magazine designed specifically for this Keltec model. It is not compatible with magazines from the FN PS90, Ruger-57, or PSA Rock.
Q: What is the effective range of this setup?
A: With the 16-inch barrel, the 5.7x28mm round is effective for most practical engagements, easily reaching 100-150 yards with accuracy. The lightweight projectile is velocity-dependent, so the longer barrel helps maintain its terminal performance at distance. The real strength, however, is rapid, controlled fire at closer ranges.
