OD: 1.625”
The Otter Creek Labs Polonium K is a compact, hard-use 5.56 suppressor built from H900 heat-treated 17-4 stainless steel in a CNC welded tubeless design. It is 4.8 inches long, weighs 11.5 oz without a mount, and measures 1.625 inches in outer diameter. The 6mm bore is compatible with 5.56 NATO, .223 Remington, and all 6mm/.243 cartridges including 6 ARC, 6mm Creedmoor, 6mm Dasher, and .243 Winchester. The Polonium K uses industry-standard 1.375x24 HUB rear threads and has a 7.5-inch minimum barrel length requirement for 5.56/.223. Full-auto rated and belt-fed certified with no marketing fluff attached.
Barrel length restrictions
7.5” – 5.56/223 and 7.62×39
10.5” – 6 ARC, 6.5 Grendel and other similar cartridges
12.5” – 308, 6.5 creedmoor, 6mm creedmoor, 243 winchester and other similar cartridges
16” – 300 win mag, 7mm rem mag, 300 PRC and other similar cartridges

Full auto rated – no BS. Responsible belt fed rated on 16” 5.56 belt fed machine guns. Do not exceed 300 round strings without cool down.
*IMPORTANT NOTE* These are the listed barrel length restrictions for all of the Polonium series (Pol, Pol-K, Pol-30). You CANNOT shoot 6.5 or 7.62 projectiles through the 5.56 Polonium or Polonium-K. Meaning the 16” 300 win mag restriction applies to the polonium-30 and not the polonium 5.56 because you cannot shoot 300 win mag through the 5.56 suppressor. You would think something like that doesn’t need to be said but you’d be surprised.
