G&P Stoner 63 M-LOK Bottom Rail Insert

Create a clean, minimalist M-LOK mounting surface beneath the barrel of your G&P Stoner 63 airsoft replica. The Bull Craft Bottom Rail Insert fills the open space along the bottom of the receiver and provides five usable M-LOK slots for compatible accessories.

This insert is designed to be used in place of a conventional handguard. It installs inside the lower portion of the receiver beneath the barrel, creating a streamlined bottom rail without surrounding the barrel with a full handguard assembly.

Manufactured from SLS-printed Nylon PA12 and finished in black, the insert works with both AEG and HPA builds. Installation requires no drilling, permanent modification, or additional mounting hardware.
