The Marucci RCKLESS Comp JBB -10 USSSA Baseball Bat is built for hitters who want pure speed, explosive barrel response, and a smooth two-piece composite feel from the first pitch. No loading screens. No warm-up lap. Just a mid-loaded USSSA bat designed to help players swing fast, play bold, and keep the scoreboard moving.
Built with a FLEX Composite Barrel, the RCKLESS Comp JBB delivers maximum barrel flex, extreme responsiveness, and an explosive sound on contact. The barrel is designed to create a wider sweet spot with consistent performance across the hitting surface, giving hitters more confidence to attack pitches and stay aggressive in the box.
The OLS Connection creates an extremely stiff connection while helping reduce vibration on contact, giving players a strong and smooth swing feel. Paired with the PFX Composite Handle, which is engineered by weight drop to enhance swing speed, power, and feel, this bat is built to bring comfort and performance together.
Finished with Ring-Free Barrel Construction, a TFX Endcap, Custom-Molded Hand Taper, Optimized Knob Design, and an Enhanced Soft-Touch 1.75mm Grip, the Marucci RCKLESS Comp JBB USSSA bat is made for hitters who want fast hands, effortless power, and all-game comfort.

OPTION GUIDE: Should I order this bat stock/untouched or Heat Rolled with Progressive Pressure?
If you order your new bat Heat Rolled with Progressive Pressure, it will be delivered to you completely and evenly broken in. This process adds 20-40ft of distance to your solid hits, increases consistency, improves durability and adds 2-3 business days of lead time to your order. If you plan to use the bat in an official game or event, please verify the legality of our process with your league or sanctioning body before use. We (LongballBats.com) do not encourage the use of a Heat Rolled bat in any game or event where it is against the rules. Click here for details about our process!
