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. Purchases include up to one (1) .5oz bottle of lapping compound at no extra cost per order.

 

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.

The best lapping tools ever!
I was really skeptical about paying a higher price for your lapping tool but I must say that I'm incredibly pleased with the results.  First off, I ordered both AR-15/AR-10 tools and they are perfectly engineered and machined hunks of metal. The fit and finish is pristine. Their weight alone  should convince anyone these are professional quality tools.  I was also unsure of your lapping compound but I used it and was very impressed. It worked quite well.  I had my AR-10 lapped in under 20 minutes and that was going slow.  If you like to build ARs then the BART kit is a must!
