Also known as: Snake, Snake DBR, Gilboa DBR
Overview
The Gilboa Snake DBR (Double Barrel Rifle) is a side-by-side double-barreled AR-15 platform rifle developed by Israeli manufacturer Silver Shadow and launched in 2013. The civilian version uses two independent triggers, two bolt carrier groups, two gas systems, and two magazine wells (or a proprietary 60-round dual magazine), allowing two rounds to be fired in rapid succession from the twin 16-inch barrels spaced 30 mm apart. The double-trigger configuration keeps the design legal under U.S. ATF rules, while the law-enforcement variant uses a synchronized single trigger that fires both barrels simultaneously.

Notes
The Snake's twin barrels each have independent point-of-impact adjustment screws to converge the rounds at a chosen distance. A 2018 update introduced a true gas-operated double-barrel configuration with internal captured spring system, allowing folding stocks.
Background
The Gilboa Snake was conceived after Israeli close-protection operators reported needing to put two rounds on a single threat as fast as physically possible - Silver Shadow's designers concluded the simplest answer was to issue them two rifles bolted together.
