Hoffman Tactical FRT

Hoffman Tactical FRT Features

The Hoffman Tactical FRT stands out with its innovative forced reset mechanism, which resets the trigger automatically for faster follow-up shots. This design is tailored specifically for compatibility with mil-spec components, ensuring a reliable fit without the need for extensive modifications.

• Custom Mounting Block: Designed to fit perfectly in Hoffman Tactical V2.8 and V3.0 AR-15 Lowers, as well as the V1.0 AR-9 Lower, with potential adaptability for other AR-15 platforms with minor adjustments.
• Unique Safety Integration: Features a safety component mounted into the block using a roll pin, with a captured spring for secure operation.
• Simplified Assembly: Replaces the factory disconnector with a custom plate, eliminating the need for the disconnector spring, making installation straightforward.

This design prioritizes functionality, ensuring that the trigger must be in the fallen position during upper-to-lower assembly for optimal performance. It's a practical upgrade for enthusiasts seeking enhanced trigger control and efficiency.

Difficulty & Build Time

• Skill Level: Intermediate
• Estimated Build Time: 4-6 hours
• Required Experience: Familiarity with AR-15 assembly and 3D printing; basic knowledge of firearm trigger systems recommended.

Hardware and Tools Required

Required Hardware

• 3/8" long by 3/32" diameter roll pin (can be cut down from an AR-9 roll pin)
• AR-15 bolt hold open spring (standard and widely available)
• Standard mil-spec semi-auto trigger and hammer

Recommended Tools

• 3D printer for printing the components
• Cutting tool for modifying the roll pin if needed
• Screwdrivers or Allen keys for AR-15 assembly
• Pliers for handling small components
• Safety gear for handling firearm parts

Hoffman Tactical FRT Parts

The Hoffman Tactical FRT package includes STL files for the essential components of this forced reset trigger modification. Key parts include the mounting block, safety component, and the plate that replaces the factory disconnector. For optimal results, print these files with a high infill percentage (at least 80%) to ensure durability under stress.

It’s recommended to use strong materials like PETG or ABS to withstand the mechanical forces of firearm operation. Pay attention to layer adhesion and avoid warping by using proper bed adhesion techniques. Detailed build instructions are available as a PDF guide at this link for step-by-step assembly guidance.

Printer Compatibility & Settings

The Hoffman Tactical FRT files are compatible with most FDM 3D printers capable of handling detailed prints, such as Ender 3, Prusa i3, or similar models. For materials, PETG or ABS is highly recommended due to their strength and heat resistance, which are crucial for firearm components; PLA is not advised as it may not withstand the stress of operation.

Set your printer to a layer height of 0.2mm or finer for precision, with a nozzle temperature of 230-250°C for PETG or 240-260°C for ABS, depending on your filament. Use a heated bed (60-80°C for PETG, 90-110°C for ABS) to prevent warping. Ensure proper cooling and support structures for overhangs to maintain the integrity of small features in the design.

Conclusion

The Hoffman Tactical FRT is a game-changer for AR-15 enthusiasts looking to elevate their firearm’s performance with a forced reset trigger system.
