## Overview

Wheeler’s 320 Grit Bore Lapping Compound is a premium silicon carbide abrasive paste designed for smoothing firearm bores, bolt faces, and lugs. Packaged in a convenient 1 oz jar, it’s part of a progressive grit system (220, 320, 600) that ensures a flawless, polished finish. Trusted by gunsmiths, this compound enhances firearm accuracy and longevity, backed by a 1-year warranty.

## Description

Wheeler's Bore Lapping Compounds are available in three grits: 220, 320, and 600. This combination of lapping grits allows for cutting (220), smoothing (320), and polishing (600) your firearm's bore. The compound is useful for a variety of applications including lapping bores, bolt faces, and bolt lugs. When lapping a bore, pressure will likely increase with grit impregnated bullets. Due to the likely increase of pressure, light loads are recommended. Five shot strings up to a maximum of twenty shots of each grit are recommended. Use progressively finer grits to reach a significantly smoother bore. Each 1 oz jar includes high-quality silicon carbide abrasive paste.

## Features

- SPECS: 1oz jar of 320 grit (smoothing) lapping compound
- FUNCTION: Used for lapping the bore of a firearm, bolt face, bolt lugs and other applications where a perfect final fit or a lapped smooth surface is needed
- VERSATILITY: Offered in three grits 220 (cutting), 320 (smoothing) and 600 (polishing)
- CONVENIENT: Repeating the process using progressively finer grits will produce a significantly smoother bore

    Easy to use.
  

*by E***K on Reviewed in the United States on October 10, 2024*

Easy to use. Like the quality finish that it leaves. Handy for lapping mating metal to metal parts for a good seal. Works great on valve seats!

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Better than JB bore paste....
  

*by J***S on Reviewed in the United States on May 9, 2023*

JB's bore paste always left a somewhat dull finish after use.The Wheelers compound polished the bore of my rifle to a mirror finish in 30 strokes.Rifle bore copper fouling now less than 50% of what it used to be.

### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars







  
  
    Great for lapping gun barrels
  

*by A***R on Reviewed in the United States on November 28, 2022*

Needed a good lapping paste as I was having issues with my chamber being too tight. About a half hour of polishing and got everything to mate together as it should. Saved me a good bit of money and works as described.
