Original GG&G manufacture plates. Also fits pinned collapsible stocks.
Note: CAR-15/M4 plate requires gunsmith/armorer installation as the receiver extension tube requires specific tools for removal and reinstallation, including a torque wrench to re-tighten it to factory safety specs. All other standard plates are user-installable, as well as the GG&G "Agency" adapter (also available) which requires no disassembly of the weapon.
