Product Overview
MCX CSMR® Button - A MCX version of our popular M4 CSMR button. The MCX CSMR mag button features the same 8 degree raked face for a more natural finger placement. Installs low enough to clear reciever fencing or as far off the reciever as desired. Offered in our "Apex" face (a mild yet grippy texture) to accomodate both the agressive or more conservative style of MCX's. Also included is one of our 302 Stainless Mag Catch Springs (also available separately for purchase here) for even smoother compression, Patent Pending.
Also compatible with Sig MPX, M400 Switchblade, M400 SDI VTAC, 716i, & 762G2 (the ambi bolt release may prohibit button from sitting below recevier fencing on 716G2).
Only includes 1x Button & 1x Spring
