About this product

<h1>FRT-RD3 (Ambi) Two-Stage (3-Position) Forced Reset Trigger for the HK MP5, MP5K, SP5 &amp; SP5K</h1> <p>The FRT-RD3 (Ambi) Two-Stage (3-Position) Forced Reset Trigger for the HK MP5, MP5K, SP5 &amp; SP5K represents a precision-engineered upgrade from Rare Breed. This trigger system is designed to deliver a distinct shooting experience through a forced-reset mechanism that re-engages the hammer immediately after each shot, allowing the shooter to maintain a rapid cycling rhythm without modifying the firearm's internal operating system. Built specifically for the HK roller-delayed blowback platform, this unit is a direct drop-in replacement for factory trigger packs in MP5, MP5K, SP5, and SP5K models.</p> <h2>Overview</h2> <p>Rare Breed has developed the FRT-RD3 to provide a genuine two-stage trigger pull with a third selectable position. This is not a binary trigger or a conversion device; it is a mechanically complete trigger pack that uses a forced-reset sear geometry. The ambidextrous selector allows the shooter to choose between safe, semi-automatic, and the forced-reset mode. Each position is tactile and audible, with no modifications required to the host firearm. The FRT-RD3 (Ambi) Two-Stage (3-Position) Forced Reset Trigger for the HK MP5, MP5K, SP5 &amp; SP5K is manufactured from heat-treated steel and billet aluminum components, with a Mil-Spec hardcoat anodized finish for durability.</p> <h2>Features &amp; Specs</h2> <ul> <li>Ambidextrous 3-position selector with safe, semi, and forced-reset settings; designed for right- and left-handed shooters</li> <li>Two-stage trigger pull with a distinct wall before the break; forced-reset function returns the trigger forward automatically after each discharge</li> <li>Drop-in design for HK MP5, MP5K, SP5, and SP5K platforms; no permanent modifications, filing, or gunsmithing required</li> <li>Manufactured by Rare Breed in the United States; category: Triggers; constructed from 4140 steel and 7075-T6 aluminum</li> <li>Includes all necessary pins and springs for installation; compatible with factory lower receivers and aftermarket housings</li> </ul> <p>The forced-reset technology in the FRT-RD3 (Ambi) Two-Stage (3-Position) Forced Reset Trigger for the HK MP5, MP5K, SP5 &amp; SP5K operates by using the bolt carrier's forward movement to mechanically push the trigger forward after each shot. This resets the sear engagement point, allowing the shooter to pull the trigger again from the same tactile position. The two-stage design gives a consistent 4.5 to 5.5 pound pull weight in semi-automatic mode, with a slightly lighter take-up in forced-reset mode.</p> <h2>Who It's For</h2> <p>This trigger is intended for experienced shooters and HK platform enthusiasts who want a performance upgrade that changes the manual of arms without altering the firearm's classification. It is suited for range use, competitive shooting events that allow forced-reset triggers, and collectors who appreciate mechanical innovation. The FRT-RD3 (Ambi) Two-Stage (3-Position) Forced Reset Trigger for the HK MP5, MP5K, SP5 &amp; SP5K requires the user to understand the fundamentals of trigger control and recoil management, as the forced-reset function demands a deliberate finger release between shots. It is not recommended for novice shooters or for use in rapid-fire drills where the shooter cannot maintain consistent trigger discipline.</p> <ul> <li>HK MP5, MP5K, SP5, and SP5K owners seeking a non-permanent trigger upgrade</li> <li>Shooters who want a two-stage trigger with an additional forced-reset mode for faster follow-up shots</li> <li>Individuals familiar with forced-reset technology who already own compliant firearms in their jurisdiction</li> </ul> <h2>Shipping &amp; FFL</h2> <p>This item is a firearm component and ships directly to your residence in most states.
