The EFFEN 90 PS90 Custom Billet Receiver is one of those upgrades that will make your PS90 look amazing. The EFFEN 90 has its own unique serial number and replaces the Factory FN upper receiver. Perfect for your next SBR project.
The EFFEN 90 uses the same action and lower assembly as the regular PS90. The Effen 90 Upper Receiver is a stripped component that requires additional parts for assembly and operation. You must either purchase the optional parts kit or move the parts over from your factory upper receiver.
