SSS.6.236 - FOR Systems MK12 Mod FOR and the M4A1 Mid-Gas 5.56x45mm 14.5-in Barrel Automatic AR15 Rifle

The Front of Rifle Systems MK12 Mod FOR is a 6mm reflex rifle silencer that produces competitive 5.56 NATO suppression performance on the standard M4 rifle with a shorter effective length than many silencers. Additionally, due to being constructed from 3D printed titanium, the MK12 Mod FOR is lighter than many competing models. The silencer uses similar technology found in the FOR Monarch Recce and Predator 6.5 silencers, in a reflex configuration that fits back over the user’s barrel using any mounting solution compatible with the OPS INC MK12 thread and taper interface used for the legacy OPS INC 12th Model silencer originally designed by Phil Seberger and Manufactured by Ron Allen, now seen in the Allen Engineering AEM5. Users installing reflex silencers must remain mindful of available space on their exposed gun barrel to avoid interference with rails and accessories.

In this review, the Front of Rifle Systems MK12 Mod FOR performance metrics depend upon suppressing a supersonic centerfire rifle cartridge on a commonly fielded gas-operated rifle, which is an incredibly difficult task. How would the MK12 Mod FOR perform on your M4 with a 14.5-in barrel?

SSS.6.213 - Otter Creek Labs OCM5 and OCM6 and the M4A1 Mid-Gas 5.56x45mm 14.5-in Barrel Automatic AR15 Rifle

The Otter Creek Labs OCM5 and OCM6 rifle silencers are modern high performance reflex models sharing external aesthetic similarities with the historic OPS INC reflex silencers designed by the late Phil Seberger and manufactured by Ron Allen. Internally, the 5.56 mm bore OCM5 uses a highly efficient hybrid core design to provide extreme pure suppression performance, at the expense of higher back pressure. The 6 mm bore OCM6 uses a more modern Infinity core derivative and exhibits lower back pressure with a decrease in pure suppression performance compared to the OCM5. Both silencers may be easily mounted to standard AR-15 barrels using over-the-barrel (OTB) mounts from Otter Creek Labs, as long as there is adequate clearance aft of the barrel shoulder. These silencers provide “military clone” OPS INC silencer enthusiasts modern design options.
