The Rare Breed FRT Locking Bar Performance Upgrade Service is a gunsmithing service that tunes the locking bar mechanism of your existing FRT-15 trigger for more reliable operation. This rare breed frt locking bar upgrade targets the stock locking bar spring, which can kink or pinch and cause malfunctions during firing, replacing and re-machining the affected components. It sits alongside the rest of our FRT trigger parts and upgrades.
This is a tuning service for a trigger you already own, not a complete firearm. Confirm the modification is legal in your jurisdiction, follow your state and local laws, and you must be of legal age and eligible to purchase.

| Service type | Send-in performance tuning of your FRT-15 locking bar |
| Spring upgrade | Stock small spring replaced with a larger, more robust spring and a steel plunger |

What the service does
Technicians substitute the original small spring with a larger spring and steel plunger, then precisely machine both the trigger body and the semi-auto locking bar sear so the new components align and function correctly. Correcting the locking bar geometry removes the kinking and binding that lead to dead triggers and intermittent failures, leaving you with smoother, more dependable operation. Prefer a drop-in alternative? Compare our FRT-15 ALB adjustable locking bar.
How the send-in process works
You ship your existing FRT-15 trigger to the facility, the modifications are completed, and the upgraded trigger is returned to you. Turnaround depends on current workload, so check the latest estimate at checkout before sending your trigger in. It is part of the broader reliability work we offer across the full forced reset trigger range.
Frequently asked questions
Do I send in my own trigger? Yes. This is a service performed on the FRT-15 trigger you already own. You mail it in and it is returned after the upgrade.
Does it change the trigger’s function? The work targets reliability of the locking bar mechanism. Confirm any modification complies with the laws in your area before proceeding.
