Blackout and Marauder receivers available in various configurations.
Blackout receivers are built from A383 grade aluminum and are approximately 90% aluminum content compared to most AEG receivers which use a zinc alloy ranging from 5-10% aluminum content. This greatly improves the strength of the receiver while reducing the weight and brittleness.
Marauder receivers are made from a fibreglass infused polymer.
“Bare” receivers are just the receiver with no hardware or internals
“Combo” receivers are bare upper+lower receiver together
“Assembled” receivers are fully built and are ready to drop in
These are for standard V2 gearboxes and hardware, but fitment may be required. Most brands are compatible with minor fitment.
