BRT EZTune Gas Tube - Carbine

The Black River Tactical (BRT) EZTune Gas Tube revolutionizes AR-15 gas system tuning by placing a precision-machined orifice directly in the gas tube rather than requiring adjustable gas blocks. This elegantly simple approach reduces gas system flow like traditional adjustable gas blocks while eliminating moving parts, adjustment screws, and complex mechanisms that can fail or require maintenance. The EZTune tube installs in under 10 minutes with only a gas tube roll pin punch, making it the fastest path to optimized gas flow for suppressed rifles with pinned gas blocks or permanent muzzle devices.

Available in multiple port sizes tailored to specific barrel gas port dimensions, the carbine-length EZTune tube allows shooters to select the precise restriction needed for their configuration. Black River Tactical provides detailed sizing recommendations based on barrel gas port diameter, suppressor use, and barrel length, ensuring optimal function without guesswork. The precision-ported orifice corrects excessive gas drive from barrels with oversized gas ports, taming violent cycling and reducing wear on bolt carrier groups and buffer systems. For shooters uncertain about sizing, BRT's customer service assists with selection based on specific build parameters.

The EZTune gas tube delivers approximately 5,000-10,000 rounds of service life depending on port size and use intensity, after which the tube can be replaced as a consumable component. This set-and-forget solution proves ideal for dedicated suppressor hosts, pin-and-weld builds, or rifles with low-profile gas blocks where traditional adjustable systems require complete handguard removal for tuning. The carbine-length variant suits 10.3-13 inch barrels with carbine gas systems, providing reliable gas reduction without the complexity of mechanical adjustable gas blocks.
