Glock-Mod Anti-Walk Pins for the AR-15
Pros & cons
What works
- 416R stainless steel construction resists corrosion in all environments
- 0.154 inch diameter maintains perfect fit in standard AR-15 lowers
- Eliminates pin walk in high-round-count binary trigger systems
- 7.6 gram total weight adds negligible mass to your build
- Survives 5,000+ rounds without adjustment or maintenance
Trade-offs
- Not compatible with SD-3G Geissele triggers due to clearance issues
- Requires complete trigger group removal for installation
- No installation tool included - requires separate punch set purchase
- Minimal benefit for mil-spec trigger users firing under 500 rounds annually

About this product
Glock-Mod Anti-Walk Pins for the AR-15 are precision-machined hardened steel pins engineered to eliminate hammer and trigger pin walk in AR-15 platforms running drop-in trigger groups, particularly binary or enhanced trigger systems. These pins provide a permanent solution to the common issue of pin migration that can cause malfunctions and reliability problems during rapid fire scenarios while maintaining compatibility with standard AR-15 lower receivers.
What are Glock-Mod Anti-Walk Pins used for?
Anti-walk pins prevent hammer and trigger pins from walking out during rapid fire or high-vibration shooting scenarios. They're essential for maintaining reliability in binary trigger systems like our Glock FRT triggers where standard pins tend to migrate under sustained rapid cycling. The installation takes approximately 15 minutes with basic tools.
How do Glock-Mod Anti-Walk Pins compare to KNS Precision anti-rotation pins?
Glock-Mod pins offer superior corrosion resistance with their 416R stainless steel construction compared to KNS Precision's standard stainless. While KNS uses spring-tensioned C-clips, our design employs a solid retention system that withstands over 5,000 rounds without requiring adjustment. The KNS system provides slightly easier installation but requires more frequent maintenance checks.
What do Glock-Mod Anti-Walk Pins weigh and what are their dimensions?
Each pin weighs 3.8 grams and measures exactly 0.154 inches in diameter by 1.25 inches in length. The complete two-pin set adds only 7.6 grams to your lower receiver weight. The pins maintain the standard AR-15 pin dimensions while incorporating precision-machined retention grooves that are cut to within 0.0005 inch tolerance.
Who should not buy Glock-Mod Anti-Walk Pins?
These pins are overkill for shooters running factory mil-spec trigger groups that rarely experience pin walk issues. If you primarily shoot slow-fire precision or your AR-15 sees fewer than 500 rounds annually, standard pins will serve you adequately. They're also not compatible with certain polymer lower receivers that require proprietary pin designs.
What comes in the package with Glock-Mod Anti-Walk Pins?
The package includes two anti-walk pins, one for the hammer and one for the trigger position. Each pin is individually packaged in anti-corrosion paper and includes basic installation instructions. Unlike our complete trigger kits, no specialized tools or additional components are included.
Are Glock-Mod Anti-Walk Pins worth $16.95?
At $16.95, these pins provide critical insurance against trigger group failure for high-round-count shooters. Considering a single pin walk-induced malfunction can cost you a competition stage or hunting opportunity, the investment is justified. They're substantially more affordable than replacing a damaged trigger group while providing permanent protection.

Frequently asked questions
- Are these compatible with Polymer80 AR-15 lowers?
- Yes, they work with Polymer80 and other polymer lowers, but require careful installation to avoid cracking the receiver. Use a padded vise block and apply even pressure during installation. The 0.154 inch diameter matches standard AR-15 specifications.
- Does this work with Geissele triggers?
- They're compatible with all Geissele drop-in triggers except the SD-3G model. The pins have been tested with SSA-E, G2S, and SDE triggers for over 2,000 rounds without issues. Installation requires removing the trigger group from the lower receiver.
- How long does standard shipping take?
- Standard shipping from our Dallas warehouse takes 3-5 business days for continental US orders. Express shipping cuts this to 2 days for an additional $12. All orders ship within 24 hours of payment confirmation.
- Can I return these if they don't fit my build?
- Returns are accepted within 30 days if the pins are unused and in original packaging. We cover return shipping if the product is defective. Custom builds may require additional measurement verification before purchasing.
- Do these require special tools for installation?
- Basic armorers tools are sufficient: a roll pin punch set and hammer. No specialized tools are needed beyond what's required for standard AR-15 disassembly. The entire installation process takes about 15 minutes for experienced builders.
