Overview

The SLR Rifleworks Synergy Comp 5.56 Mod1 California Legal is the premium muzzle device for a featureless build, and it earns the price by removing the guesswork. SLR sells two versions of the Synergy Comp: the standard model and an explicitly California-legal model that, in SLR's own words, delivers the same performance as the standard comp without the flash-suppression capability. For a California featureless rifle, where a device that functions as a flash hider is a prohibited feature, buying the variant the manufacturer markets as the California model removes the interpretation risk entirely.

It is machined from 416 stainless with a melonite finish and threads 1/2x28 onto a standard 5.56 barrel. The Synergy design is a well-regarded recoil and muzzle-rise reducer, and the California Mod1 keeps that tuning while dropping the flash-mitigation geometry. At around $114 it is the most expensive option in this guide, and the value is the certainty of running a device the maker built specifically to clear the California feature test.

The state-specific rule still applies. The Synergy Comp California model is a California answer; it remains a banned feature in New York, which prohibits muzzle brakes, compensators, and threaded barrels on featureless rifles. There is no muzzle device that is simultaneously a featureless upgrade in California and legal on a New York featureless build, because the two states regulate opposite things.
