TranQuilo Sound Suppressor M308

TranQuilo Sound Suppressor M308

The LaRue TranQuilo was designed and engineered for the LaRue 7.62x51 family of rifles, but it’s right at-home on any precision .308 with a 5/8-24 threaded muzzle (1/2-28 threaded adapters also available). The TranQuilo is 100% CNC machined from stainless steels, reduces sound to hearing-safe levels and flash signature to almost zero. CNC machining of all components results in near zero point-of-impact shift when comparing on/off repeatability. This is critical for the majority of users who remove and attach their suppressor between shooting sessions.

The TranQuilo’s reduced-blowback is what sets it apart. The design approach implemented what LaRue calls “SOT” (Safer Operator Technology). With mitigation of gas blow-back in mind, LEPE (Lower Ejection Port Emissions) reduces dangerous materials and contaminants that typically encounter the user's face. LEPE is an internal design that allows a percentage of pressure to bypass the main flow-path, resulting in extremely low gas blow-back and soft recoil with the benefit of optimum noise and flash reduction.

All components manufactured from a combination of 17-4 PH Stainless Steel and Incoloy A-286. 17-4 PH (Precipitation Hardening) Stainless Steel is a robust chromium-nickel grade of stainless, hardened by a precipitation-hardening treatment. Incoloy A-286 is an age hardenable, Iron-Nickel-Chromium alloy designed for applications requiring high-strength and excellent corrosion resistance. 

All components are precisely engineered to fit together solidly and perfectly. There are no welds to fail, or dimensionally migrate as heat builds up (shifting your bore centerline). There is no need to “fix” crooked bore centerlines with wire EDM. All parts are in perfect alignment when assembled. Accuracy is what LaRue is about, and we do it right the first time.

To ensure the suppressor remains locked when attached, a captive locking-ring securely grips the suppressor to the adapter. Along the tube, knurled bands provide structural robustness as well as added grip for installation and removal. This profile also helps keep mirage covers from slipping forward during extended periods of use. On the endcap, an open, angled, four-prong flash-reducing tip reduces the small residual muzzle flash.

The Muzzle-Brake Adapter is also precision-machined from 17-4 PH Stainless Steel. Even though the TranQuilo was designed as a .308 suppressor, it also works well on .223 rifles. Adapters are available in both 5/8-24 and 1/2-28 threads. The Adapter’s patented dual-shouldered design seats the suppressor in perfect alignment to the bore, and eliminates gas from escaping to the rear of the suppressor, keeping attachment threads clean and free of carbon.
