Product Overview
AICS-Compatible Foundation for the KT10
The KT10 lower is the serialized foundation of an AR-308-style platform designed around AICS-pattern magazines. It gives experienced builders a purpose-built starting point for modern short-action cartridges that do not fit comfortably within a standard AR-10 magazine.
- Designed for AICS-pattern short-action magazines
- Precision-machined from billet aerospace-grade aluminum
- Includes the proprietary magazine release and manually operated bolt catch
- Works with a Kaliber Tech bolt carrier group or a compatible carrier modified by Kaliber Tech
- Serialized receiver that must ship to a valid FFL
Move Beyond the Limits of a Standard AR-10 Magazine
A conventional AR-10 magazine limits overall cartridge length and narrows the range of bullets and chamberings a builder can use. The KT10 lower changes the magazine interface to accept AICS-pattern magazines, giving the rifle a maximum cartridge overall length of 2.955 inches while preserving an AR-style operating layout.
The result is a practical foundation for precision-oriented semi-automatic builds in chamberings such as 6.5 PRC, 6.8 Western, .270 WSM, 7 SAUM, and .300 WSM.
What Is Included
- One serialized KT10 lower receiver
- One proprietary KT10 magazine release
- One manually operated KT10 bolt catch
Compatibility and Required Components
The KT10 lower is designed for AICS-pattern magazines and requires a Kaliber Tech bolt carrier group or a compatible carrier modified by Kaliber Tech for the KT10 magazine geometry. The platform uses AR-308 and DPMS-pattern components where indicated, but dimensions and compatibility vary across manufacturers. Confirm each major component before completing your build.
If you want the proprietary lower, upper, bolt carrier group, and magazine supplied together, choose the KT10 Builder's Kit instead.
FFL Transfer
The KT10 lower is a serialized receiver and must ship to a valid Federal Firearms Licensee. We will need a current copy of your receiving dealer's FFL before shipment.
Frequently Asked Questions
Will a standard AR-10 magazine work?
No. The KT10 lower is designed around AICS-pattern magazines.
Can I use an existing bolt carrier group?
The carrier must be compatible with the KT10 magazine geometry. Use a Kaliber Tech bolt carrier group or contact Kaliber Tech about modifying a compatible carrier.
Can the lower ship directly to me?
No. The serialized lower must ship to a valid FFL for transfer.
Which chamberings can I build?
The KT10 lower is designed around AICS-compatible short-action cartridges. Final chambering depends on the upper, barrel, bolt, magazine, and other components selected for the build.
