CGS’s Void rifle line—Void 762, Void 556, and compact Void 556K—is a Florida-branded, Otter Creek Labs–built family aimed at shooters who want Polonium-like performance without chasing the absolute quietest or lightest can on the market. Host MrGunsnGear frames the partnership as a request for a capable, affordable rifle suppressor that does most jobs well rather than winning every spec sheet. Full-size 5.56 and 7.62 Voids are widely described, including by Otter Creek staff, as functionally similar to Polonium Gen 2, a platform already popular for its performance-to-price ratio.

Design, mounts, and materials

The cans ship with a tool, hub-compatible mounts (5/8-24 on .30, 1/2-28 on 5.56), and wrench flats on both the mount and the suppressor body so carbon-locked parts can be broken free with opposing wrenches. Internal depth is limited: some older Keymo mounts may bottom out before the first baffle. Construction is welded baffles in 17-4 stainless with no outer tube over a separate core, which the host says keeps internal volume up without extra diameter and weight. Each unit includes two interchangeable end caps—vented for less back pressure and solid. A shorter K model simply uses fewer baffles. Muzzle flash in the video is attributed partly to dusk filming and PMC X-Tac M193, not CGI; flash-hiding caps remain an option.

Range testing and verdict

Sound was measured with a military-spec meter: CAT 4 rifle at 1.6 m height, meter 1 m left, plus a Daniel Defense V7P with a 10.3-inch barrel using Armscor 147-grain and subsonic loads from Firearms Depot. Unsuppressed baselines were followed by full-size and K cans and a non-vented cap; first-round pop and a rare rifle malfunction were noted. Exact dB figures are left to on-screen graphics. The host’s take: not the quietest, cheapest, or lightest, but a balanced package with slightly less back pressure and more features than a standard Polonium at roughly 10% more cost. CGS sent the samples with no editorial control over meter data.

Pros

Polonium Gen 2–like performance at a still-competitive price
Hub mounts, wrench flats, and dual end caps
Welded 17-4 stainless suited to short barrels, high round counts, and full-auto/FRT heat
Lighter than some same-size steel cans by 8–10 oz

Cons

Heavier than premium lightweight designs
Not class-leading in sound reduction
Shallow blast chamber may conflict with some older Keymo mounts
Visible flash in low light with certain ammo
