Why Shooters & Professionals Choose Otter Creek Labs

In the modern firearms industry, finding silencers that balance peak sound reduction, manageable gas flow, and indestructible build quality is difficult. Products from otter creek labs were engineered to shatter legacy compromises. By combining DMLS additive manufacturing with automated laser-welded 17-4 stainless steel and grade-5 titanium, OCL produces silencers that survive grueling firing schedules while setting industry sound performance records.

Hard-Use Rifle Suppression: Polonium-30 & Infinity 556k

Rifle shooters require maximum durability without unbearable blowback. The Otter Creek Labs Polonium-30 provides duty-proven performance across 5.56, 6mm, 6.5 Creedmoor, and .300 Win Mag with exceptional tone and signature reduction. For short-barrel carbines where gas blowback is a primary concern, the OCL Infinity 556k vents high-pressure gas forward to keep cycling clean, smooth, and pleasant for the operator.

Subgun Speed & Lightweight Precision: Lithium 9 & Hydrogen Series

For 9mm subguns and PCCs, excess muzzle weight destroys handling. The OCL Lithium 9 Suppressor weighs under 6 ounces, making it one of the lightest full-auto rated 9mm cans in existence.

Frequently Asked Questions

Everything you need to know about purchasing, mounting, and shooting Otter Creek Labs products.

What mounting system do Otter Creek Labs suppressors use?

Most Otter Creek Labs centerfire rifle and subgun suppressors (including the Polonium series, Infinity 556k, Lithium 9, and Hydrogen series) feature industry-standard 1.375×24 HUB rear mounting threads. This allows you to run direct-thread adapters (like the OCL ZR0 DTA) or mount any popular quick-detach adapter including Rearden Atlas/Plan B, Dead Air KeyMo, SilencerCo ASR, or 3-lug systems.

Are Otter Creek Labs suppressors full-auto rated?

Yes. OCL 17-4 stainless steel suppressors like the Polonium series are full-auto rated with no minimum barrel length restrictions. Titanium models like the Lithium 9 and Hydrogen series are extremely durable and rated for rapid fire on 9mm and normal firing schedules on precision centerfire hunting calibers.

Can I shoot 5.56 ammunition through the Polonium-30?

Yes. The Polonium-30 features a .30 caliber bore, allowing it to safely and effectively suppress 5.56 NATO, 6mm ARC, 6.5 Creedmoor, .300 Blackout, .308 Winchester, and up to .300 Win Mag. Running 5.56 through the Polonium-30 also results in significantly lower backpressure compared to dedicated tight-bore 5.56 cans.

What is the warranty policy on Otter Creek Labs suppressors?

Otter Creek Labs provides a hassle-free, no-nonsense lifetime warranty on all suppressors. If your suppressor is damaged through normal hard use, baffle strikes, or manufacturing defects, OCL will repair or replace it promptly.
