Extra Glass fiber makes it feels like metal.
In full Geissele Super Duty marking, this receiver shell is best paired with a Kublai blowback gearbox. A special nylon composite with metallic material mix is used to make this shell that gives a special metallic feel to it.
- Because of the composite material(nylon with metallic material) used, this receiver is very brittle and are prone to cracking.
