Now Available, B.A.R.T. 1.0 in M4E1 and M5E1 sizes to fit the new enhanced AR uppers.  They will not properly lap the standard uppers so please use the standard-sized B.A.R.T. tools for that purpose.

 

All B.A.R.T. Combo Purchases include one (1) .4oz bottle of lapping compound at no extra cost.

 

Barrel And Receiver Truing Tool

Whether you are a professional armorer, gunsmith, or hobbyist, if you work on AR's you cannot afford to be without this set of tools.

*NOTE: When lapping with the B.A.R.T. Tool, it is recommended to use a hand-driver and manually turn to lap your upper, and in a pinch, a power-driver/drill can be used with discretion (on low), but *DO NOT* use an impact driver as this can damage or break the bit extension on the B.A.R.T. Tool.

It is strongly advised to utilize the B.A.R.T. Tool in a horizontal fashion.  Using it vertically in combination with lapping compound can allow the compound to run inside the upper receiver's bolt-carrier channel and cause the unintentional removal of anodizing in that location.
