Guntology KRYON HEX Burn Protection System (NEXUS Barrel Mount)

This is the KRYON HEX shield on Guntology's NEXUS barrel mount, the configuration Guntology sells for fast-attach suppressors that do not use the 1.375x24 HUB interface. The shield is the same CNC-machined 6061-T6 aluminum tube as the HUB version, vented with an open hex pattern around its full circumference and standing off from the suppressor body rather than wrapping it.

NEXUS is a two-piece, rifle-side mount. A low-profile caliber insert goes on the barrel behind your existing QD muzzle device and is captured when the muzzle device is torqued. The NEXUS adapter carries the shield and locks onto that insert with a ratchet mechanism, so the suppressor still mounts and dismounts normally, and the adapter and shield can move to any other rifle fitted with an insert. Guntology lists the adapter at under 0.8 oz and 0.20" of added length, and NEXUS configurations ship with a Lock Ring.

Order it for a 5.56/.223 host with 1/2x28 threads or a .308/7.62 host with 5/8x24 threads. NEXUS is designed around a 90-degree barrel shoulder; a tapered-shoulder barrel needs a taper adapter and a muzzle device that seats on the resulting square shoulder. Shield length (5" to 8") is set from the suppressor brand and model on the order form, backed by Guntology's fit guarantee and lifetime warranty.
