Upgrade your 10/22® bolt hold open (B-41) to a fast auto-release system

Rack the bolt with a single pull—no more fighting the factory hold-open.

• Smooth, frustration-free bolt operation
• Laser-cut stainless steel construction for long-term durability
• Standard on all KIDD complete triggers—now available as a standalone upgrade

• Function: Auto bolt release—bolt closes with a simple rearward pull
• Compatibility: Works with factory triggers and all KIDD complete triggers

Why KIDD’s auto release works better

The factory Ruger® bolt hold open requires an awkward, inconsistent press to drop the bolt. KIDD’s replacement part reshapes the internal engagement surface so the bolt snaps forward automatically once the shooter pulls it rearward.
The component is cut from stainless steel for consistent geometry and long service life—no bending, no tuning, and no breaking in. The result is a faster, cleaner, more intuitive bolt-running experience.

Installation & break-in tips

• Remove trigger group from receiver before starting
• Partially push out the ejector pin (B-35) and magazine release latch pin (B-35) from the bolt-hold-open side
• Pull out the factory B-41 bolt hold open
• Slide in the KIDD Auto Bolt Release
• Reinsert the magazine release latch pin fully
• Ensure the bent arm of the spring seats correctly in the ABR notch
• Fully reinstall the upper ejector pin
• Test engagement: actuate the ABR and confirm it springs cleanly back into place

Fine-tune your 10/22® trigger with precision weight-tuning springs for the KIDD “Trigger Job” Kit.

What makes it special

• Lets you dial in your ideal trigger-breaking weight
• Replaces the factory B-40 plunger spring in Ruger® 10/22® polymer trigger groups
• Improves both pull weight and reset consistency
• Color-coded spring options from 2.25lb to 3.75lb
• Helpful if your trigger isn’t resetting reliably

Key specs

• Designed for use with the KIDD “Trigger Job” Kit
• Fits Ruger® 10/22® polymer trigger guards
• Five included springs with ˜ approximate break weight: No Color 2,25, Orange 2.5, Red 3, Green 3.25, Blue 3.75 lbs
• Legacy kits with painted ends- white = new dyed orange
• Affects both trigger pull and return weight
• Tolerance-flexible for variations in factory housings

Fine-tuning your trigger — what to expect

These springs allow you to choose your desired trigger-breaking weight when paired with a properly installed KIDD “Trigger Job” Kit. Because Ruger® polymer trigger housings vary slightly in tolerance, final break weights are approximate. If your trigger occasionally fails to reset, stepping up to the next-stronger spring may resolve it.

Installation & break-in tips

• Pre-installation guidance:
• The spring sits directly behind the trigger blade with a plunger capping it.
• To access it, you must remove internal components including the hammer and the sear/disconnect/trigger blade sub-assembly.
• Use a slave pin to keep the sear/disconnector/trigger blade together during removal.
• Disassembly overview:
• Remove trigger group; de-cock the hammer with safety off
• Remove hammer strut assembly
• Remove ejector, bolt hold-open elements, and hammer
• Hold back the trigger blade while removing the trigger pin to prevent the plunger spring from ejecting
• Installation overview:
• Insert the trigger sub-assembly while holding the trigger blade plunger in place
• Replace slave pin with supplied dowel pin
• Reinstall hammer and spring assembly
• Reinstall bolt hold open, ejector, and magazine latch pin
• Cock hammer, re-engage safety, and verify proper movement
• Test safety engagement: trigger must not fire with safety on

If safety function is not correct after installation, contact KIDD for assistance.

Package includes

• Five weight-tuning springs (No Color, Orange, Red, Green, Blue) and slave pin
