Our take: This metal hop-up chamber unit by DBoys is perfect for M4/ M16 series AEG rifles. Constructed out of durable shatter-resistant metallic composite, this hop-up is designed for maximum performance and is a cost effective alternative to other similar hop-up chamber units that can cost more than $25!
NOTE: Although this hop-up chamber unit is ready to use out of the box, professional installation is recommended/may be required.
