MPX Slip Trip Kit (Rev. 2)

NOT COMPATIBLE WITH MCX OR MPX COPPERHEAD!!! Rev. 2 Note: The MCX/MPX Trip Kit has been altered to offer better reliability for the MPX with a dedicated version for each MCX and MPX separately. Rev. 1 users do not need to change to Rev. 2, anyone with significant issues with Rev. 1 (primarily MPX users) should reach out to support and we'll resolve them. To use the super safety/ARC-Fire in the MPX, you will need a super safety or ARC-Fire, standard AR FCG, and this slip trip kit. This kit includes a lever blocker built-in to the trip guide so you do not need to purchase the separate lever blocker.
