The FRT-15 ALB Adjustable Locking Bar is a self-contained, drop-in replacement locking bar that lets you adjust trigger release timing on a forced reset trigger. This frt-15 alb adjustable locking bar swaps in for a worn or non-working factory locking bar without changing the semi-automatic function of the trigger. It is one of the most useful tuning pieces in our FRT trigger parts and tuning components.
This is a replacement trigger part for forced reset trigger platforms. Always follow your state and local laws, and you must be of legal age and eligible to purchase.

Fixes common forced reset trigger issues
The ALB addresses three frequent problems in a single drop-in part. It corrects dead triggers and light primer strikes caused by hammer follow from an early release, it replaces locking bar springs that kink and cause spongy pulls and reset trouble, and it adds downward and rearward spring pressure for a more positive, reliable reset. Because release timing is adjustable, it also lets you run different buffer weights and springs. It pairs especially well with the FRT-15 trigger for a fully tuned setup.
Range-adjustable and easy to install
Adjustment is done with a low-profile contact bolt and the included shims, so you can fine-tune timing right at the range. The bar is precision machined and coated for hardness, wear resistance, and corrosion resistance, and it completely eliminates locking bar return spring kinking or binding, the kind of reliability focus that defines our full forced reset triggers range.
Frequently asked questions
Does it change how the trigger fires? No. The ALB does not change the semi-automatic function of the trigger. It replaces the locking bar and lets you tune release timing.
Will it fit my Gen 1 FRT-15? Yes. It fits both the original Gen 1 and the current Gen 2 FRT-15 triggers, plus WOT and Tommy Triggers platforms.
