Lantac USA RTT Rear Takedown Tool 3D Printed Stainless Steel - AR-15

The Lantac USA RTT Rear Takedown Tool is a purpose-built AR-15 armorer's accessory that drives out the rear takedown pin on a lower receiver without un-staking the pin or removing the castle nut and end plate. Made by Lantac USA, the RTT is a compact, single-piece tool produced via DLC (Direct Laser Sintered) 3D printing from stainless steel with a natural finish. The tool slips into the rear pin lug and pushes the rear takedown pin straight out, streamlining field-strip maintenance and pin-swap work.

The RTT is sized to engage the rear pin area on standard AR-15, M16, and M4 lower receivers, making it a fast, simple shop and bench accessory for gunsmiths, home builders, and armorers who need to swap out damaged or replacement pins. By eliminating the extra disassembly steps normally required to clear a stubborn rear pin, the RTT saves time during any AR-15 service or assembly task, and it is manufactured in the USA.
