Toni System +3/+4 Rounds Extended Basepad for BUL and KMR LP-S Magazines – 141mm Limit
The Toni System Extended Basepad is a high-performance competition upgrade engineered to boost firepower by adding +3 to +4 rounds to BUL and KMR LP-S platform magazines while stringently adhering to international rulebooks. In practical shooting sports, maximizing ammunition capacity within division boundaries provides a vital tactical edge. This hardware is custom-engineered to exploit structural limits, extending the assembled magazine up to the critical maximum length of 141 mm, the legal boundary for tournament check gauges.
Precision CNC-machined from a solid billet of high-grade aluminum, this extended baseplate couples exceptional structural resistance against severe impact forces (such as free-falling drops onto concrete or gravel stage bays) with an ultra-lightweight profile. Its external contouring delivers a solid, positive purchase for flawless palm-strike seating during emergency reloads.
IPSC / USPSA Division Compliance:
The layout of this extended baseplate is specifically tailored for competitive arena environments:
- Strict 141 mm Sizing Blueprint: Designed to measure exactly within the 141 mm maximum length gauge. This makes the basepad fully compliant and legal for IPSC Standard-Optics division (fitting inside the official box) as well as USPSA Limited and Carry Optics divisions, completely removing any risk of division reassignment during official gun checks.
Modular Dual-Groove Guide & Securement Logic:
Cross-platform mechanical adaptability between BUL and KMR magazine tubes is achieved through a smart internal adapter design:
- Two Dedicated Inserts Included: To match the differing structural tracks of BUL and KMR LP-S magazine bodies, the package contains two specific custom inserts. Shooters can easily identify and utilize the correct insert by matching the corresponding guiding grooves as in the picture.
- Single Locking Set Screw Allocation: The hardware features a single locking set screw for structural anchoring. Depending on your chosen magazine type, this set screw must be installed on either the left or right side. This configuration is necessary because one side of the magazine body features a factory retention tab that blocks set screw insertion; securement must strictly be executed on the opposite free-threaded channel.
Technical Specifications & Key Advantages:
- Capacity Increase: Safely adds +3 to +4 rounds to your magazine
- Premium Aluminum Construction: Rugged structural build finished with a protective anodization layer to resist abrasive operational wear.
Fitment & Setup Notice: Carefully cross-reference the alignment of your chosen internal adapter insert within the guide tracks prior to tightening. Never force the locking set screw against the side obstructed by the magazine tube’s factory indexing tab.
