KRYON – Transform Your AR Pistol into a Rifle, Legally and Efficiently

KRYON offers a simple, compliant solution to convert your AR pistol into a rifle without the hassle of obtaining an NFA tax stamp. By pinning and welding the KRYON to your barrel, you achieve the required 16-inch overall barrel length—allowing you to use a shorter, more maneuverable barrel while enjoying the benefits of foregrips and your preferred buttstock instead of a pistol brace.

Unlike traditional methods, KRYON maintains most compatibility with suppressors and muzzle devices, giving you the flexibility to customize your setup without compromise.

KRYON – Ultimate Heat and Impact Shield

KRYON is a dual-purpose heat and impact shield designed to protect your suppressor in even the harshest environments. Acting as a lightweight yet durable cage, KRYON encases your suppressor, safeguarding it from accidental impacts with hard surfaces while enhancing airflow for superior cooling performance.

Advanced Protection and Cooling

KRYON also doubles as a heat and impact shield. Acting as a durable cage around your suppressor, it safeguards against accidental impacts with hard surfaces while promoting superior airflow for efficient cooling. This design not only extends the life of your suppressor but ensures it performs at peak levels during sustained fire.

With KRYON, you get unmatched versatility, protection, and compliance—all in one sleek, easy-to-install package.

KRYON – The Smarter Alternative to Pin & Weld Muzzle Devices

KRYON offers a game-changing solution for shortening your rifle without the typical constraints of pin and welded muzzle devices. Traditionally, achieving legal barrel length requires selecting a muzzle device of precise length, limiting suppressor compatibility and saving only 2-3 inches at best.

KRYON takes this further – when using 10five, it allows for the removal of approximately 6 inches of barrel length by functioning as both a suppressor mount and an integral part of the rifle. This enables you to run a 10.5-inch barrel without requiring a tax stamp, as long as the KRYON is pinned and welded to the rifle.

Beyond compliance, KRYON enhances versatility by accommodating multiple suppressor options, giving you the freedom to choose.
