For shooters focused on precision, modularity, and real-world ergonomics, modern semi-auto pistols must balance adaptability with a clean, serviceable design. The following review examines one platform that delivers a thoughtful approach to customization and optics integration while remaining compact where it counts.
AREX DELTA L is offered in three basic variants, and each can be ordered in a factory Optics Ready configuration to accept reflex sights. 
Design and Modularity
The AREX DELTA L emphasizes modular construction: removable front and rear frame inserts carry the slide guides and the complete fire control mechanism. Critically, only the front insert is serialized and required to remain with the pistol; the rear insert and other components may be swapped to suit grip geometry, frame color, or control layout. This architecture makes maintenance and personalization straightforward for competitive shooters and professionals alike.

Variants and Optics Integration
The platform comes in three variants; the compact M variant retains the footprint of the first-generation Delta and maintains compatibility with reverse-grip frames for shooters who prefer that profile. The Optics Ready option allows direct mounting of popular reflex sights without adapters, streamlining co-witness and minimizing slide work for those wanting a low-profile electronic sight.
Why the serialized front insert matters
Because the front insert is the serialized component, owners can legally configure or service non-serialized parts without transferring the whole firearm. For armorers and serious hobbyists, that separation of responsibility between serialized and modular parts speeds repairs and customization cycles.

Practical Use and Customization
Arex has engineered this platform for shooters who want adaptability without complex gunsmithing. Whether you prefer a compact footprint or a full-size grip module, the interchangeable inserts and optics-ready slide keep options open. The slide guide design aids consistent lockup and serviceability across field stripping and maintenance cycles.
