<p>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.</p> <p>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.</p> <p>Both the Polonium and Polonium-K utilize the industry-standard 1.375x24 rear thread, allowing compatibility with a wide range of mounting systems.</p>
