NSPEC Innovations AR-15 Super Safety FRT — Straight Flat-Face Trigger | 3-Position Forced Reset
The NSPEC Innovations AR-15 Super Safety FRT with straight flat-face trigger is a 3-position forced reset trigger kit privately manufactured in Texas from CNC-machined, heat-treated 4140 steel with a DLC coating. It adds a third selector position — Super Safety (FRT) mode — that mechanically forces the trigger forward to reset after each shot, enabling rapid, controlled semi-automatic fire. In Semi mode it operates as a standard mil-spec-compatible semi-automatic trigger. This is the straight flat-face variant; a curved trigger version is also available separately at NSPEC.
The design was originally developed by Hoffman Tactical and has been refined with an updated trip bar featuring reinforced material at key stress points, making it significantly more durable than earlier-generation and budget super safety designs. A free centering block is included for shooters running M16-style lower receivers with wider trigger pockets.
Features and Specifications

- Selector positions: Safe / Semi / Super Safety (FRT) — 3-position
- Material: CNC-machined, heat-treated 4140 steel
- Coating: DLC (Diamond-Like Carbon) for hardness, low friction, and corrosion resistance
- Trip bar: Updated design with reinforced material at key stress points
- Includes: Super Safety cam, lever, safety detent pin, straight flat-face mil-spec trigger (pre-milled with Super Safety cuts), and centering block
- Centering block: Ensures proper lever alignment in M16-style lower receivers with wider trigger pockets; not required for most standard AR-15 lowers
- Origin: Privately manufactured in Texas for NSPEC Innovations
- NFA classification: Not an NFA item — does not convert the rifle to automatic fire

How the Super Safety FRT Works
The Super Safety system integrates into the rifle's existing fire control group rather than replacing the entire trigger assembly. In Super Safety mode, a cam and lever mechanism attached to the safety selector mechanically pushes the trigger forward to its reset point after the bolt carrier completes its rearward travel. The shooter still executes a complete trigger pull for every round fired — one round per pull, every time. Switching to Semi mode disengages the forced reset cam, returning the trigger to standard semi-automatic behavior. Safe functions identically to a standard safety selector.
This mechanism differs from a full drop-in FRT kit like the Rare Breed FRT-15, which replaces the entire fire control group. The Super Safety works with your existing mil-spec trigger components, adding the forced reset function through the selector rather than a new trigger group. This means your semi-auto trigger feel is preserved when the selector is in Semi mode.
Required Components and Compatibility
The AR-15 Super Safety FRT requires the following to function correctly:
- Mil-Spec Fire Control Group — the Super Safety is designed to work with standard mil-spec hammer, trigger, disconnector, and springs. Non-mil-spec triggers may not interface correctly with the cam and lever geometry.
- M16 or Full-Auto Bolt Carrier Group (BCG) — a standard semi-auto AR-15 BCG with a partial M16 cutout will not reliably activate the trip bar. A full M16-profile BCG is required for the forced reset mechanism to engage consistently.
- Minimum H2 buffer (4.6–4.7 oz) — a standard carbine buffer is too light for reliable FRT cycling. Light primer strikes or hammer follow after 1–2 rounds typically indicate the buffer is too light. Upgrade to at minimum an H2 buffer; H3 may be needed on shorter-barreled or suppressed builds.
- Low-shelf lower receiver — the Super Safety lever requires clearance behind the trigger pocket. High-shelf lowers (typically found on certain mil-surp and Colt-pattern lowers) may require minor material removal in the lower to allow the lever to travel fully rearward during cycling. Colt lowers may also have a shelf designed to block certain full-auto components, which can interfere with installation.
Not compatible with: AR-10/LR-308, AR 12-gauge, AR .22 LR, or any platform not using a standard M16-profile BCG.
Straight Flat-Face vs. Curved Trigger
The straight flat-face trigger provides a uniform vertical surface across the trigger shoe, which many shooters prefer for its consistent finger placement and the perceived improvement in leverage during the pull. A curved trigger has a standard bowed profile that naturally indexes the fingertip toward the center of the shoe. The choice between flat and curved is primarily personal preference — neither design changes the trigger's pull weight, reset, or Super Safety functionality. If you prefer the standard curved profile, the NSPEC AR-15 Super Safety FRT with curved trigger is also available.
Installation
Installation is a drop-in process that does not require modification to a standard mil-spec low-shelf lower receiver. The Super Safety components install in place of the existing safety selector using the existing detent and spring. The included straight flat-face trigger replaces the existing trigger if needed, though the Super Safety system is compatible with any mil-spec trigger that has been pre-milled with the appropriate Super Safety cuts. Full installation videos are available from NSPEC — watch both the introduction and the installation video before starting.
State Restrictions and Legal Notice
The AR-15 Super Safety FRT is not available in states that restrict rate-of-fire modifying devices or forced reset triggers. Verify your state's current laws before purchasing.
