The AR-15 Spiral Gas Tube is an easy way to increase the pressure that is available to cycle your AR-15 pistol or short barrel rifle. If this pigtail gas tube was stretched flat, it would be of a length similar to a full sized AR-15. With the direct impingement system that the AR-15 uses, this increased back pressure can mean the difference between a pistol that is fun to shoot or frustrating.

Features:

• Designed for AR-15 Pistols or Short Barrel Rifles
• Increases Cycling Reliability
• Made from Aluminum
• Easy to Install
