Wheeler Delta Series AR-15 Bore Guide

Protect Your Rifle's Bore with Proper Alignment

The Delta Series AR-15 Bore Guide is a precision-engineered cleaning accessory designed to safeguard one of your rifle's most critical components—the barrel bore. Manufactured from CNC-machined aluminum with a durable anodized finish, this bore guide ensures your cleaning rod stays perfectly aligned during maintenance.

Key Features

• Precision alignment: Prevents the cleaning rod from bowing, rubbing, or gouging the chamber and throat
• Dual retention methods: Secures in place by closing the dust cover on the upper receiver, or uses chemical-resistant O-rings for uppers without dust covers
• Convenient solvent port: Located at the rear of the guide for easy access during cleaning
• Compatible calibers: Works with .223 Remington and .204 Ruger
• Inner tube diameter: .250" (not intended for 6.8mm jags)

Why Bore Guide Cleaning Matters

Cleaning without a bore guide can allow the rod to bow and contact the bore's interior surfaces, causing real damage and loss of accuracy over time. By keeping the cleaning rod properly aligned, the Delta Series guide protects your barrel while also directing force more efficiently—making it easier to push tight patches through the bore.

The Bottom Line

This is a simple tool that does one job exceptionally well: keeping your cleaning rod centered and your bore protected. For any AR-15 owner serious about rifle maintenance and long-term accuracy, it's an essential addition to your cleaning kit.
