BoreTech Bore Guide AR

Bore Tech Bore Guide AR-15 223 556mm is a bore guide designed for AR-15 rifles in .223 Rem / 5.56 mm caliber. It aligns the cleaning rod precisely with the bore and helps protect both the firearm and the cleaning rod during maintenance. The bore guide helps prevent the cleaning rod from contacting the locking lugs and chamber edges, reducing rod scratching and firearm wear during regular cleaning.

The construction is CNC-machined from durable, solvent-resistant synthetic polymer that keeps the cleaning rod properly aligned with the barrel. Model-specific and caliber-specific dimensions support an accurate fit in the AR-15 platform, and the solvent-resistant O-ring seals against the chamber, helping prevent cleaning solvents from flowing back into the action.

The extended design positions the solvent port safely behind the optic and keeps the upper and lower receivers separated, making cleaning more convenient. The beveled rear opening makes it easier to align jags and brushes, and the enlarged solvent port allows easier application of cleaning solvent or oil to a patch or brush without unnecessary mess.

The AR-15 .223 / 5.56 mm bore guide has a length of 30.5 cm (12 inches). During cleaning, the Bore Tech AR Bore Guide adds approximately 30.5-38.1 cm (12.0-15.0 inches) to the total barrel length, depending on the model, so it is recommended to ensure that the cleaning rod is long enough before use.

Begin use by removing the BCG Bolt Carrier Group according to the manufacturer?s instructions. Insert the bore guide through the receiver until it seats in the chamber. When slight resistance from the O-ring seal is felt, stop pushing, as excessive force or pushing too far may damage the O-ring.

For cleaning, place a correctly sized dry patch on the jag and push the rod through the rear opening of the bore guide until the patch is visible in the solvent port. Then apply cleaning solvent or oil to the patch and push it through the bore. The solvent port can also be used to apply cleaning solvent to brushes. To remove the guide, gently twist and pull it out of the chamber and upper receiver.

In summary, this bore guide provides a controlled way to clean the barrel of an AR-15 .223 / 5.56 mm firearm and helps reduce wear on both the cleaning rod and the firearm. Precise alignment, solvent sealing, and a practical solvent port make it a useful accessory for regular firearm maintenance.

Recommended use: suitable for cleaning the barrel of an AR-15 .223 / 5.56 mm firearm when the goal is to guide the cleaning rod precisely and protect the chamber, locking lugs, and cleaning equipment during maintenance.
