Daniel Defense Carbine Length Gas Tube Assembly

Product Description

The Daniel Defense Carbine Length Gas Tube Assembly is a replacement or build component for AR-15 carbine-length gas systems. This assembly is manufactured by Daniel Defense for shooters building custom uppers or replacing worn gas tubes.

Gas tubes direct high-pressure gas from the barrel port back to the bolt carrier group, cycling the action. A properly fitted gas tube is critical to reliable function. Carbine-length systems are the most common configuration on 16-inch AR-15 builds.

Carbine Length vs. Mid-Length Gas Systems

Carbine-length gas tubes measure shorter than mid-length systems and pair with carbine-length gas blocks and handguards. The carbine system is standard on most 14.5-inch and 16-inch barrels. Mid-length systems require a longer tube and matching gas block position.

If you are replacing a gas tube, match the length to your existing gas block location. Mixing lengths will not function. The gas port on your barrel determines what system length you need.

Installing a Gas Tube Assembly

Gas tube installation requires a roll pin punch, a hammer, and a vise block or upper receiver vise clamp. The stainless steel roll pin secures the tube to the gas block. Drive the pin through the gas block and tube until it sits flush on both sides.

Align the tube so it enters the gas key on the bolt carrier without binding. A misaligned tube will cause cycling failures or damage the carrier. If you are not comfortable installing upper components, Western Sport offers gunsmithing services on site.

Frequently Asked Questions

Q: Will this Daniel Defense gas tube fit a mid-length gas system?

A: No, this is a carbine-length gas tube and will not fit a mid-length system. Mid-length gas tubes are longer and position the gas block farther forward on the barrel. Confirm your gas system length before ordering.

Q: What is the difference between carbine and mid-length gas tubes?

A: Carbine-length gas tubes are shorter and designed for gas blocks positioned closer to the chamber, typically on 14.5-inch to 16-inch barrels. Mid-length tubes are longer and used with gas blocks positioned farther forward. The two are not interchangeable.

Q: Is the roll pin stainless steel?

A: Yes, the gas tube roll pin is stainless steel. Stainless pins resist corrosion and provide secure retention of the tube in the gas block.

Q: Can I install this gas tube myself?

A: You can install a gas tube with basic hand tools: a roll pin punch, hammer, and upper receiver vise block. Proper alignment is critical to avoid carrier damage. If you prefer professional installation, call Western Sport at 817-393-4000 to discuss gunsmithing services.

A: Contact Daniel Defense directly or call Western Sport at 817-393-4000 to confirm warranty terms for this component.

Q: Will this gas tube work with any carbine-length gas block?

A: Yes, carbine-length gas tubes follow a standard specification and fit any carbine-length gas block with the correct roll pin hole. Confirm your gas block is carbine-length before ordering.
