RTT™ Tool – AR-15 Upper Receiver Rear Pin Removal LanTac®

The LanTac^® RTT™ tool streamlines AR-15 maintenance by allowing fast removal of the rear takedown pin—without loosening the castle nut or end plate. Machined from stainless steel using advanced 3D printing, it saves time, prevents frustration, and makes pin replacement quick and reliable.

Durable Stainless Steel Construction

Manufactured with 3D-printed stainless steel, the RTT™ is strong enough for repeated use. The precisely formed ramp ensures the detent is lifted consistently, keeping the process smooth and reliable.

Simple, Effective Design

Insert the tool into the groove on the rear pin and the angled ramp lifts the catch. The detent slides clear, allowing the pin to be removed without loosening the castle nut or end plate. No extra disassembly required.

Quick Pin Replacement

Once the pin is out, the detent holds the pivot pin in place—so a new pin can be installed immediately, without risking loss of the spring or catch. The entire process takes just minutes.

Practical in Workshop or Field

Whether repairing a damaged pin or installing a new one, the RTT™ is equally useful on the bench or at the range. Compact and simple, it’s a smart addition to any AR-15 maintenance kit.

Made in the USA

Like all LanTac accessories, the RTT™ tool is proudly made in the USA with a focus on precision and durability.
