X-Caliber AR15 (M4E1 Size) Barrel And Receiver Truing Tool B.A.R.T. 2.0 - Receiver Lapping Tool & Reaction Style Rod

Barrel And Receiver TruingTool

B.A.R.T- 2.0 is a two in one tool. Inserted into the front end, the tool laps the face of your AR Uppers, ensuring a perfectly square and centered fit between your Barrel and Upper.

With the head of the tool secured in vise, insert the other (splined) end through the rear of the upper until the splines engage the lugs of the barrel. You are now ready to loosen or tighten the barrel nut, muzzle brake, or suppressors and install gas blocks with ease and confidence without any need to remove sights or optics.

There is NO OTHER tool on the market like it. This one tool does the job of TWO TOOLS, literally saving you $100 or more! If you build or own AR’s this tool is absolutely indispensable.

*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.

All B.A.R.T. Purchases include up to one (1) .5oz bottle of lapping compound at no extra cost per order. Step 1: Tighten BART's head in a bench vise on the "Flats" provided. Step 2: Put barrel in upper. Slide barrel nut over barrel and finger tighten barrel nut to upper. Step 3: Slide upper onto BART 2.0 until barrel extension locks onto the teeth Step 4: Tighten barrel nut to upper with barrel nut wrench to specifications stated by handguard manufacturer.
