LANTAC M-SPEC 556S 5.56/.223 SUPPRESSOR - FULL AUTO RATED RIFLE SILENCER WITH HUB MOUNT
The Lantac M-SPEC 556S is a .223/5.56mm suppressor precision machined from 17-4 Precipitation Hardened Stainless Steel in H900 condition, also rated to safely accommodate 6mm ARC. Its tubeless, fully welded baffle stack uses a 360 degree full penetration laser welded design that reduces thermal distortion during manufacturing and improves baffle alignment for consistent long term performance. At 6.0 inches and 13.5 ounces excluding mount, the M-SPEC 556S is full auto rated with adequate cooling between magazines and independently tested to 130 dB under MIL-STD-1474E. The included 1/2x28 direct thread HUB adapter mounts directly onto your 5.56 threaded barrel. The M-SPEC 556S gives you HUB mount flexibility, rugged durability, and documented third party sound performance.
CAPITOL ARMORY'S OPINION
The 5.56 suppressor market has numerous options built to a price point, but the M-SPEC556S is built to a standard. The tubeless, fully welded baffle stack and the 360-degree laser welding are not just manufacturing trivia; they are what keeps baffle alignment consistent over the life of the can, which is where cheaper cans may start to fail. The 130 dB rating is also worth keeping in mind because it comes from independent testing to MIL-STD-1474E rather than an in-house estimate. Combine that with the standard HUB mounting interface, and you have a suppressor that performs well and is easy to move across hosts.
