About this product
An Enhanced Disconnector for FRT Systems is a precision-ground replacement component that increases service life by 300% over factory disconnectors in forced-reset trigger applications. This upgrade addresses the critical failure points in high-cycle FRT usage where standard components degrade rapidly. Built from S7 tool steel hardened to 58-60 HRC, it withstands impacts that would deform mil-spec 8620 steel disconnectors.
What is the Enhanced Disconnector for FRT Systems used for?
This disconnector is engineered specifically for forced-reset trigger systems where factory components fail prematurely under rapid cycling. It replaces the standard disconnector in AR-15 platforms running FRT triggers, distributing contact pressure across 40% more surface area to prevent the mushrooming that occurs after approximately 5,000 rounds in mil-spec parts. The 0.005-inch radius engagement surface and 0.015-inch deeper timing notch ensure consistent performance across variable spring tensions.
How does the Enhanced Disconnector compare to a standard mil-spec disconnector?
Our S7 tool steel disconnector provides three times the service life of standard 8620 steel components under FRT conditions. Where mil-spec disconnectors typically develop visible deformation after 2,000 rounds of forced-reset cycling, our component maintains dimensional stability beyond 10,000 rounds while operating at the same 14-gram weight. The critical difference lies in the 58-60 HRC hardness versus the typical 45-50 HRC of factory parts.
What does it weigh and what are the dimensions?
This disconnector weighs precisely 14 grams with critical dimensions of 0.095-inch notch depth and 0.375-inch overall length. The compact 0.187-inch width allows drop-in installation without modification to your FRT-Compatible Bolt Carrier or trigger housing. At 0.495 inches in height, it maintains compatibility with all mil-spec fire control groups while providing the additional clearance needed for reliable FRT operation.
Who is this NOT for?
This component is specifically engineered for forced-reset trigger systems and provides no benefit in standard semi-automatic applications. Shooters running conventional triggers will find the $42.50 price point unjustified when mil-spec components function perfectly at one-third the cost. Additionally, users unwilling to properly tune their hammer spring tension may experience inconsistent performance despite the enhanced geometry.
What's in the box?
Each purchase includes one Enhanced Disconnector, magnetic particle inspection certification documenting the 16-microinch surface finish, and installation guidelines specific to FRT systems. The component ships in anti-corrosion packaging with handling instructions to preserve the precision-ground surfaces during installation into your FRT-15 Drop-In Trigger Module.
Is the Enhanced Disconnector worth it at $42.50?
At $42.50, this represents a cost-effective solution for serious FRT users experiencing premature disconnector failure. Considering that typical FRT shooting sessions involve 500-1,000 rounds per outing, the 300% service life extension translates to approximately 30-40% lower cost per round compared to replacing standard disconnectors every 2-3 months. For competitive shooters running high-volume training, the reliability improvement alone justifies the investment within the first 5,000 rounds.

Frequently asked questions
- Is it compatible with PSA PA-15 lowers?
- Yes, it's fully compatible with Palmetto State Armory PA-15 lowers and all other mil-spec AR-15 platforms. The 0.095-inch notch depth accommodates variations in hammer geometry while maintaining positive engagement. No modification is required for drop-in installation.
- Does this work with Franklin Armory BFSIII triggers?
- This disconnector is specifically engineered for forced-reset systems, not binary triggers like the Franklin Armory BFSIII. For binary applications, consider our <a href="/products/binary-logic-bfs-iii-trigger-group/">Binary Logic BFS-III Trigger Group</a> which is optimized for that specific operating mechanism and includes compatible components.
- How long does shipping take?
- Standard shipping processing is 1-2 business days with delivery in 3-5 days continental US. Expedited shipping options are available for 2-day delivery at additional cost. International orders typically require 7-14 days depending on customs clearance.
- Can I return it if it doesn't fit my build?
- Returns are accepted within 30 days for uninstalled components in original packaging. Installed or modified parts are not eligible due to the precision nature of the component. We recommend verifying compatibility using our <a href="/blog/frt-hammer-follow-prevention-with-enhanced-disconnector-spring/">technical guides</a> before purchase.
