Zenitco selection guide

Choose the right Zenitco handguard system

Quick answer: choose the model family by platform length first, then select the mounting interface. B-10 models are compact; B-30 and Sport-1 cover longer configurations; Sport-4 and Leader systems are intended for full-length 415 mm configurations. Confirm the exact platform and upper component before ordering.

Compact B-10 systems

B-10L

A lightweight compact model with Basis interfaces on the sides and lower section.

B-10LS

Compact format with side Basis interfaces and a reinforced lower interface.

B-10U

Balanced compact configuration with Basis interfaces on the sides and lower section.

Compact model with Picatinny rails on three sides for Picatinny-mounted accessories.

Long and full-length systems

B-30 family

Choose B-30 for a three-sided Picatinny layout or B-30U for a mixed Basis and Picatinny configuration. Compatible upper options include B-31, B-31S, B-31L and B-31N, subject to the selected lower model and platform.

Sport-1 family

The Sport-1 and Sport-1S kits combine side and lower Basis interfaces with a continuous top Picatinny section. The S version uses a reinforced lower interface.

Sport-4 family

Sport-4 systems extend beyond the gas-tube area and are intended for compatible 415 mm configurations. They are not a substitute for Sport-1 on shorter variants. Review the Sport-4 kit details before ordering.

Leader family

Leader and Leader-S are extra-long matched systems for compatible 415 mm configurations. They provide Basis interfaces with an additional mini-Picatinny section for a carefully planned accessory layout. See the Leader kit.

Selection checklist

Identify the exact platform variant and configuration length.
Choose the interface: Basis for a low-profile modular layout, Picatinny for direct Picatinny accessory mounting.
Match the upper component: compact B-10 systems use B-19-family options; B-30 systems use compatible B-31-family options; Sport and Leader products are matched kits.
Check every product page: confirm listed compatibility, included components and installation requirements before checkout.

Frequently asked questions

B-10M uses Picatinny rails on three sides. B-10U uses Basis interfaces on the sides and lower section.

Can B-19 and B-31 upper components be interchanged?

They belong to different length groups. B-19-family options are used with compatible compact systems, while B-31-family options are paired with compatible long systems.

Are Sport-4 and Leader systems suitable for every configuration?

No. These full-length systems are listed for compatible 415 mm configurations. Confirm the exact platform on the product page before ordering.
