Compatibility Tags
Overview
The TriggerTech SIG MCX Adaptable trigger is the adjustable MCX path for shooters who want to dial in pull weight rather than accept a fixed 4.5 lb duty trigger. The mapped curved SKU adjusts between 2.5 and 5.0 pounds and is built specifically for the SIG MCX trigger pocket.
The TriggerTech release system gives the trigger a low-creep, crisp break feel while keeping the unit self-contained. Key components are 440C stainless steel in a 7075 aluminum housing. This is the black curved SKU ARC-TBB-25-NNC.
The flat ARC-TBB-25-NNF variant is also available separately. For pure duty rotation, the Geissele Super MCX SSA remains the more conservative fixed-weight pick; choose the TriggerTech when adjustability matters more.

Cons
- −Premium pricing, comparable to the Geissele Super MCX SSA
- −Match-derived feel may be too light for duty rotation when set below 3.5 lb
- −Aluminum housing is lighter but less rugged than Geissele tool-steel construction
- −Adjustable design adds a wear component compared to fixed-weight competitors
