About this product
The Screw for the Right Side Ambidextrous Selector Lever for the FRT-RD3™ (AMBI) is a 4140 steel heat-treated fastener engineered specifically for Rare Breed Triggers' forced reset trigger ambidextrous selector systems. It delivers precision fitment across all Glock generations from Gen 1 through Gen 6, ensuring reliable performance under sustained fire. This component represents the exacting standards required for binary trigger systems where tolerance stacking can make or break function.
What is the Screw for the Right Side Ambidextrous Selector Lever used for?
This screw secures the right-side selector lever to the FRT-RD3™ ambidextrous trigger housing. It maintains constant tension on the lever during rapid cycling, preventing play that could cause misfires or selector wobble. The 45 HRC heat treatment ensures it won't strip under repeated installation cycles or heavy recoil impulse.
How does this screw compare to the standard Glock selector screw?
This 4140 steel screw outperforms standard Glock factory selector screws by maintaining torque retention through 500+ round count sessions. Factory screws average 28-32 HRC hardness and will deform under sustained binary trigger use, while this component holds its 12 in-lbs torque specification through thermal cycling and vibration. For ambidextrous FRT systems, this is the definitive upgrade.
What does it weigh and what are the dimensions?
The screw weighs 0.8 grams with overall dimensions of 6mm length and 3mm thread diameter. The precision-machined Allen head accepts both 1/16” (1.58mm) and 2mm wrenches, providing installation flexibility. This minimal mass prevents adding noticeable weight to the trigger assembly while maintaining structural integrity.
Who is this NOT for?
This component is specifically engineered for Rare Breed Triggers FRT-RD3™ systems and offers no benefit for standard Glock trigger setups. Shooters running stock connectors or competing in production divisions should consider the Glock-Mod 3.5lb Connector instead. It also provides zero function for left-hand-only shooters who don't utilize ambidextrous controls.
What's in the box?
The package contains one 4140 steel screw, one 1/16” Allen key, and one 2mm Allen key. No thread locker or installation instructions are included—this is a component for builders who already understand their platform. The inclusion of both metric and SAE wrenches covers 95% of armorers' tool kits without requiring additional purchases.
Is the Screw for the Right Side Ambidextrous Selector Lever worth it at $110?
At $110, this screw delivers critical reliability for $2000+ binary trigger systems where failure isn't an option. Compared to the cost of a malfunction during dynamic shooting, it's insurance against downtime. For builders investing in complete FTR trigger systems, this component ensures right-side selector integrity through thousands of rounds.

Frequently asked questions
- Is it compatible with Glock Gen 5?
- Yes, it's engineered for all Glock generations from Gen 1 through Gen 6. The thread pitch and length match Rare Breed Triggers' specifications precisely across all double-stack models. No modifications required for Gen 5 frames.
- Does it fit Polymer80 frames?
- Only if using Rare Breed Triggers' FRT-RD3™ system specifically designed for P80 platforms. Standard Polymer80 frames without the FRT trigger housing will not accept this screw. Confirm your trigger system before purchase.
- How long does shipping take?
- Orders ship within 24 business hours via USPS Priority Mail, typically delivering in 2-3 days continental US. International shipments require 7-10 days with customs documentation. Tracking numbers provided immediately upon shipment.
- Can I return it if it doesn't fit?
- Returns accepted within 30 days if components are unused and original packaging intact. Custom-fit trigger components like this screw require compatibility verification before purchase—check your FRT-RD3™ model number against product specifications.
- Does this work with Glock 43X?
- No, this screw is designed for full-size and compact double-stack Glock models only. For slimline platforms like Glock 43X, consider the <a href="/products/⚡-new-glock-mod-glock-43-43x-48-frt-v2-drop-in-trigger-bar-kit-flat-or-curve-aluminum-shoe-w-steel-curved-trip/">FRT V2 Trigger Bar Kit</a> which includes appropriate hardware for single-stack applications.
