Ruger 10/22 Viton Bolt Buffer & Stainless Trigger Assembly Pin Kit
Upgrade two common contact points in the Ruger 10/22 action with one simple kit. The Pete's Pillars P7643-BLK combines one of our Viton bolt buffers with a pair of close-tolerance stainless steel trigger assembly pins for a cleaner, more secure 10/22 setup.
The Viton bolt buffer helps cushion rearward bolt impact and reduce mechanical action noise, while the stainless trigger assembly pins replace the loose-fitting factory-style pins that retain the trigger housing in the receiver.
One Kit. Two Useful Ruger 10/22 Upgrades.
This package includes the components needed to upgrade one Ruger 10/22:
- 1 Viton bolt buffer sleeve
- 1 stainless steel bolt buffer center pin
- 2 stainless steel trigger assembly pins
Together, they address both bolt impact at the rear of the receiver and unwanted looseness in the trigger housing pin locations.
Viton Ruger 10/22 Bolt Buffer
The factory Ruger 10/22 uses a rigid bolt buffer at the rear of the receiver. Our replacement combines a resilient Viton outer sleeve with a stainless steel internal pin to cushion the bolt as it reaches the end of its rearward travel.
- Helps reduce bolt impact during cycling
- Reduces mechanical action noise compared with a rigid factory-style buffer
- Genuine Viton construction provides excellent resistance to many common oils, cleaners and solvents
- Stainless steel center pin provides durable internal support
- Especially useful in suppressed 10/22 builds, where mechanical action noise may become more noticeable
Close-Tolerance Stainless Trigger Assembly Pins
The two included stainless steel trigger assembly pins replace the factory-style pins used to retain the trigger housing in the Ruger 10/22 receiver.
Our pins are intentionally produced for a closer, more secure fit. This helps reduce the loose or sloppy fit sometimes found with factory trigger housing pins and makes the pins less likely to move freely during disassembly or handling.
- USA-made stainless steel
- Close-tolerance fit
- Helps reduce trigger housing pin looseness
- Corrosion-resistant construction
- Pair included – enough for one Ruger 10/22
- Replacement application for Ruger B5-style trigger assembly pins
A Tighter Fit Is Intentional
These trigger assembly pins are designed to fit more closely than many factory pins. Installation may require noticeably more effort in a tight receiver.
Receiver dimensions vary, and paint, coating or other surface finishes inside the pin holes can further reduce available clearance. If a pin does not install normally, do not force it. Verify receiver dimensions and remove any coating interference as appropriate before installation, or have the fit checked by a qualified gunsmith.
Ruger 10/22 Compatibility
Designed for the Ruger 10/22 platform and many aftermarket receivers using the standard Ruger-style bolt buffer and trigger housing pin arrangement.
Aftermarket receivers can vary in dimensions, so installed fit may differ slightly from one receiver to another.

Installation
Always confirm the firearm is completely unloaded before beginning installation.
- Remove the barreled action from the stock according to the firearm manufacturer's instructions.
- Remove the factory bolt buffer and trigger housing pins.
- Start the stainless bolt-buffer center pin approximately halfway into the Viton sleeve.
- Position the Viton sleeve through the receiver's bolt-buffer openings.
- Push the stainless center pin completely through the installed Viton sleeve.
- Reinstall the trigger housing using the two Pete's Pillars stainless trigger assembly pins.
- Reassemble the firearm and verify proper function before use.
