The Combat Application Technologies Kitty Kat (CAT KK) is a compact centerfire 6mm rifle silencer intended for high pressure applications on short barrels. The combination of suppression performance and back pressure reduction of the CAT KK is unprecedented for its size. At a total length of 4.75-in with its included mount, the silencer provides hazard reduction that meets or exceeds that of a significant amount of models on the current market, in a very competitive form factor. The length-truncated implementation of SURGE BYPASS technology in the silencer demonstrates the further industry advancement in hybrid designs that continue to eclipse the performance of legacy systems.

SSS.6.196 - Otter Creek Labs Infinity and the M4A1 Mid-Gas 5.56x45mm 14.5-in Barrel Automatic AR15 Rifle (Free Version)

The Otter Creek Labs Infinity is a severe-use mid-size 30 caliber rifle silencer with an advanced but flexible hybrid design. In the role of a 5.56 rifle silencer, it is considered full-size. The silencer is user-configurable for different blast load flow states and allows the operator to adapt the system to a variety of host weapons. With a high early-time flow rate, the silencer may perform well on semiautomatic platforms even in its most restrictive configuration. For sensitive platforms, the user may fully vent blast loads from multiple stages of the silencer, lowering back pressure to a minimum for this design. The Infinity is 3D-printed from Inconel alloy and is expected to offer significant durability for hard use. The vented end cap configurations of the Infinity produce performance that scales well with increasing barrel lengths.

In this review, the Otter Creek Labs Infinity 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 Otter Creek Labs Infinity with three of its different end caps perform on your M4 with a 14.5-in barrel?

The Dillon DRC556 is a somewhat compact dedicated 5.56mm rifle silencer with extreme muzzle suppression performance for its size. Constructed entirely of 3D-printed Inconel alloy, the silencer also offers the requisite durability for heavy firing schedules. The DRC556 is HUB-mountable and produces gross free field muzzle blast suppression on supersonic rifle platforms on par with that of much larger silencers; with its included direct thread mount, the silencer is only 5.75-in long. This performance, for form factor, is extremely significant. The back pressure induced by the DRC556 is not significantly high, though it is somewhat higher than some competing models in this performance class.

The BOE Mod 1 is a full size multi-core rifle silencer. With its 5.56 core and solid end cap, the Mod 1 exhibits significant overall signature suppression performance, and its back pressure may be reduced with the use of a vented end cap. The outer tube of the BOE Mod 1 system is titanium, and the user may choose silencer cores of both different caliber and different material (Inconel or titanium). The 3D-printed cores are "swappable” by the user, from the manufacturer. Material choice, end cap choice, and core bore size choice will dictate user experience in blast overpressure suppression, depending on weapon system selection. The silencer’s core geometry provides a significant amount of surface area, which is one of factors producing its high muzzle suppression performance.
