Sonicore Rekkr OB 5.56mm Aluminum/Steel Suppressor - Direct Thread

Maximize acoustic dampening while maintaining compact weapon handling with the Sonicore Rekkr OB (Over-Barrel) .223 Remington Suppressor. Manufactured in the United States by Lyman Products, Sonicore adapts time-tested European reflex suppressor engineering for modern American semi-automatic rifles. By utilizing an over-barrel (reflex) configuration that telescopes back over the barrel rather than hanging entirely off the muzzle, the Rekkr OB adds minimal effective length to the rifle's front end while retaining the generous internal expansion volume required to drastically tame blast pressure, sound signature, and felt recoil.

Built for enhanced semi-automatic firing schedules, the Rekkr OB features a hybrid material architecture combining a 6026-T9 aluminum exterior with a rugged 303 stainless steel core and blast-diverting inserts. The suppressor integrates an internal stainless steel muzzle brake engineered with rotational gas-disrupting grooves that harness expanding propellant gasses to continuously tighten the suppressor onto the barrel shoulder during fire—preventing carbon-lock or dangerous loosening. Featuring a modular multi-section body that allows users to remove modules for an ultra-compact footprint, a stepped-down rear collar designed to clear common AR-15 handguard inner diameters, and aggressive external knurling for rapid heat dissipation and slip-free handling, the Rekkr OB delivers premium reflex performance at an outstanding value.

Features

Over-Barrel (Reflex) Architecture:
Telescopes back over the barrel contour (accommodating barrel outer diameters up to .754″) to capture high expansion volume while adding significantly less overall length to the weapon system than standard muzzle-mounted suppressors.

Self-Tightening Internal Muzzle Brake:
Equipped with an integrated stainless steel muzzle brake featuring gas-disrupting geometry that imparts a rotational vector on exiting gasses, continuously torqueing the suppressor tight against the muzzle shoulder during firing strings.

Hybrid Steel-Core & Aluminum Construction:
Engineered with lightweight 6026-T9 aluminum outer baffle modules surrounding high-strength 303 stainless steel baffle inserts, balancing severe-duty thermal erosion resistance with agile front-end rifle balance.

Modular Adaptable Length:
Features a modular baffle design that enables shooters to remove segments to shorten the overall profile when maximum agility and compact carry take precedence over sound suppression.

AR-15 Handguard Clearance Step-Down:
Machined with an engineered step-down profile at the rear collar, facilitating seamless tucking and compatibility within common free-float AR handguard inner diameters.

Heavy Knurled Heat Dissipation Exterior:
Features deep surface knurling across the tube that increases surface area for accelerated radiative cooling while providing a non-slip tactile purchase for installation and removal.

Direct-Thread 1/2x28 Simplicity:
Threads directly onto standard 1/2x28 rifle muzzles without requiring expensive proprietary muzzle adapters, alignment shims, or complex quick-detach locking collars.

Protected Strategic Serialization:
Serial numbers are strategically engraved away from high-risk baffle and end-cap strike zones, preserving critical legal markings in the event of an accidental alignment failure.
