Our take: This tubular handguard conversion kit by JBU serves as a perfect addition for anyone looking to modify their M4 AEG into an ultra-compact, streamlined CQB rifle. This handguard features a flat black finish and is CNC machined from a solid piece of aluminum, providing added stability and support. It also sports a knurled surface that gives you a rough non-slip grip on the rifle. Thanks to the free-float design, this tubular handguard is much more studier than standard M4 handguards, eliminating any sign of wobble. Weighing in at only 4.8oz, this tubular handguard adds virtually no weight to a standard M4 AEG.
The JBU conversion kit also includes a reinforced outer barrel that runs 6.5 inches long and a high precision inner barrel with an internal diameter of 6.03 millimeters, making shooting more accurate and at higher FPS. Because this handguard replaces the standard delta ring assembly, it is compatible with most metal gearbox M4 AEGs. Making this a complete front conversion kit, the included steel front iron sight comes complete with taper pins and is adjustable for elevation. JBU's Tubular Free-Floating Handguard Conversion Kit is perfect for any airsoft player looking to convert a standard length M4 AEG into a shorty CQB rifle, while maintaining a streamlined look. All necessary components for installation are included, such as a CNC-machined barrel nut, taper pins and tightening tool; however, professional installation may be required.
