MM BK1S Magwell Flare (Magazine Sleeve Edition)

Running the MM BK1S Mag Sleeve on your magazines? The standard magwell flare won't clear it — this MM BK1S Magwell Flare (Magazine Sleeve Edition) is reshaped specifically to work with the sleeved magazine as well as a normal, unsleeved magazine, so it's the safer all-round pick if you're not sure which magazines you'll be running.

The trade-off is a small one: this edition retains roughly 80% of the smooth, funnel-like guide feel of the original flare, since the geometry has to accommodate the extra bulk of the sleeve. If you never use the Mag Sleeve and want the smoothest possible mag insertion, the original MM BK1S Magwell Flare is the better match. Either way, it's a simple bolt-on replacement for your BK1S's magwell rather than a permanent modification to the blaster.
