The Blackbird F556 is a mid- to full-size 5.56 rifle silencer with very high suppression performance and a relatively balanced flow rate. The advanced hybrid design of the F556 is offered in both titanium and Haynes 282 alloy versions and offers requisite durability and weight options based on user needs. At only 5.4-inches in length without a mount, the HUB-compatible F556 not only offers universally high suppression performance, but exceptionally competitive performance for the length. While first round signature is somewhat more severe than with some other silencers in this high performance class, its overall performance is extremely notable.

In this review, the Blackbird F556 performance metrics depend upon suppressing a supersonic centerfire rifle cartridge on a short-barrel gas-operated rifle, which is an incredibly difficult task. How would the Blackbird F556 perform on your MK18 with a 10.3-in barrel?
