KEL STOCK ADAPTER KIT AR SU-16 - Tactical Upgrade for Enhanced Performance

The KEL-TEC stock adapter kit for the SU-16 opens up a whole world of ergonomic and modularity options for shooters who want to customize their platform. This adapter bridges the gap between the SU-16's piston-driven reliability and the massive aftermarket ecosystem of AR-15 components. Whether you're looking to dial in a stock that fits your frame better, add adjustability for different gear or shooting positions, or simply modernize your rifle's controls, this kit lets you bolt on most standard AR-style stocks to your SU-16.

The beauty of the SU-16 is that it's a self-contained, compact carbine that doesn't need much to run—but if you want to add that modular feel and flexibility, the adapter kit does the job without compromising the rifle's inherent simplicity. Installation is straightforward, and the design maintains compatibility across the full SU-16 lineup, so whether you own an older model or a newer variant, this upgrade works. The kit also functions with the SU-22 for shooters working across caliber platforms.

This is a smart move for anyone who's outgrown a fixed stock or wants to match their SU-16 to a specific loadout. AR-pattern stocks are plentiful, affordable, and come in collapsible, fixed, and adjustable lengths—so once you install this adapter, you're not locked into one setup.
