Details

Active reset for the SIG MCX. The Rev 2 Slip Trip Kit puts a Super Safety or ARC-Fire V2 in your MCX 5.56, 300 Blackout or 7.62×39. It is the dedicated MCX version, running a standard AR fire control group or a Geissele MCX FCG.

What’s in the kit

Slip Trip: 4140 steel, heat treated, black oxide
Slip Trip Guide: 7075-T6 aluminum, Type III hardcoat anodized with PTFE (Teflon)
Lever blocker built into the guide: no separate lever blocker purchase needed

Compatibility

Fits	SIG MCX 5.56, MCX 300 BLK, MCX 7.62×39, all generations (early gens may need the safety latch removed)
Requires	Super Safety or ARC-Fire + standard AR FCG (or Geissele MCX FCG) + this kit
Does not fit	MCX .308 or MCX .277 Fury (those need the MCX Heavy kit; ask us), or MPX (use the MPX kit)

Geissele note: Super Safety-cut Geissele triggers work, but if you are running a Super Safety, do not use the MCX/MPX-specific Geissele models; that hammer will not work with the system.

Not compatible with: Atrius Super Selektor, factory Timney trigger, or drop-in cassette triggers of any brand. Do not use any cassette triggers. Some fitment work may be required, as with all aftermarket accessories.

Complete the build

Gunsmith installation recommended. SIG SAUER trademarks referenced for identification only; modification may void the firearm’s warranty.

Laws on assisted reset triggers vary by state and locality and can change. Check the laws where you live before you order. Buyer is responsible for compliance with all applicable laws.
