Features
The Polonium is a rugged, duty-rated 5.56 suppressor designed for hard use, available in standard and K (short) lengths. For the best balance of size, weight, price, and sound suppression, the Polonium series is unmatched. Its real-world performance and track record speak for themselves—no inflated dB numbers or marketing hype needed.
The Polonium’s 6mm bore is compatible with all 6mm/.243 cartridges. Its highly effective built-in flash hider significantly reduces muzzle flash, especially in low-light or night vision conditions. The distinctive design incorporates external weight reduction, strategically removing excess material without sacrificing strength. This results in a suppressor with 10% more surface area (depending on length), promoting faster heat dissipation and cooling.
Both the Polonium and Polonium-K utilize the industry-standard 1.375×24 rear thread, allowing compatibility with a wide range of mounting systems.
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
- 18” – 300 RUM and 300 Norma mag
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.*
