C.S has spent the last two years iterating this upper from concept to working prototypes. Now moving from 3D prints to metal production, the Contact Front AR Conversion Upper brings a purpose-built platform for shooters who want a compact, reliable upper that uses the ubiquitous Ruger 10/22 barrel.

Key design priorities:

•Works with standard AR-15 lowers and accepts a standard AR trigger group for fast, familiar installation and serviceability.

•Engineered to work with both full-auto (FA) form-factor lowers and selectable forced-reset (FRT) link systems — compatibility tested with common FA/FRT lower geometries.

•Early prototype runs used 3D-printed disintegrating links for testing; production will ship with machined steel/aluminum components and industry-standard fasteners.

•Compact footprint and a 10/22 barrel interface give you light weight, simple parts availability, and inexpensive barrel options.

Pre-order now to lock in the $399 introductory price. We’re limiting this offer to 20 buyers to fund final production tooling and QC. MSRP on final release will be $999.

•Compatibility: Standard AR-15 lower receiver (mil-spec fit).

•FA/FRT: Designed for compatibility with full-auto style lowers and forced-reset link devices.

•Barrel: Uses standard Ruger 10/22 barrel interface.

•Prototype link type: Disintegrating links (3D printed used in prototyping; production parts will be metal and 3D depending costs).

•Construction (production): CNC machined aluminum receiver, hardened steel internal wear points.

•MSRP: $999 (expected).

•Pre-Production: $399 (limited to 20). / Pre-order $699 (limited 100)

•ETA (target): Jul 4th, 2026 (we aim to ship earlier if possible).
