SSS.6.179 - Otter Creek Labs Infinity and the MK18 5.56x45mm Short Barrel Automatic AR15 Rifle

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.

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 perform on your MK18 with a 10.3-in barrel, with three of its different end caps?
