Meet the Manticore X Lower for Ruger® 10/22®, a groundbreaking upgrade that marks the next phase in the evolution of the Manticore series and 10/22 style firearms. This modernized system is meticulously designed with modularity as its core objective, offering a level of customization that sets it apart from conventional 10/22® builds.

For those seeking “the full package,” be sure to also get the PRO Bundle for Manticore X! This discounted combo includes our M-LOK® Forend, AR hiveGrip, and Folding Picatinny Buttstock to provide you with everything you need for the ultimate upgrade.

Unlike traditional 10/22® chassis or stocks, the Manticore X boasts a lightweight, integrated trigger assembly and chassis design. This seamlessly mounts to Ruger® 10/22® receivers, barrels, and a myriad of aftermarket accessories to offer the ultimate advancement in customization and modularity. Its compatibility extends beyond the ordinary, allowing shooters to explore diverse configurations tailored to their preferences.

The heart of the Manticore X is  a pre-assembled housing ready to accept AR style grips with or without tangs. The lower doesn’t just stop at grip compatibility as Manticore X also supports picatinny mounted buttstocks, braces, sling swivels, and more to accommodate a wide array of accessories. Additionally, the Manticore X Lower also features an integrated QD sling mount reversible for left or right side use.

The Manticore X comes fully assembled and ready to rock with all of the features of the original Manticore and more including:

• Ultimate Trigger Kit: A lightened trigger pull with a textured, flat-faced Victory Trigger Shoe

• Trigger adjustability: adjustable for over-travel and pull-weight from approximately 2.25lbs to over 5lbs

• Cornerstone Rotary Safety: Ambidextrous, short throw rotary safety selector

• Bolt Keeper Extended Bolt Lock: auto bolt release and enlarged actuation knob for simplified use

•  Fireswitch Extended Magazine Release: textured face and bi-directional actuation; push or pull to drop magazines

• Aerospace grade aluminum: CNC machined housing with matte black anodized finish

• Enlarged trigger guard: supports large or gloved hands; features index points for memorable ready position

• Direct grip mount: accommodates AR compatible pistol grips with or without a beavertail

• Direct stock/brace/sling mount: rear picatinny mount for stocks, slings, or braces; can be configured for inline or 12° downward pitch to customize stock angle

• Integral QD rear sling mount: swappable to left or right side

• Upgraded pins: includes self-capturing rubberized Shock Block Bolt Buffer to replace steel bolt stop pin and ball-detent Upgraded Receiver KrossPins

• Pin Storage: dedicated retaining holes in lower to store KrossPins and Shock Block Bolt Buffer when disassembled

• Free floating barrel: The barrel is free-floating from the chassis, allowing for superior accuracy

Manticore X uses TANDEMKROSS’s self-capturing Upgraded Receiver KrossPins as a universal takedown mechanism. This method offers improved accuracy and reliability over a detachable barrel system. Fixed barrel and takedown receiver owners can now break down and reassemble their firearm without any shift in point of impact (POI) as the barrel, receiver, and optic remain fixed. The Manticore X works with both takedown and non-takedown receivers.
