KOLIBRI.works LIEVIQ (PRO and SIM)
 
Switching to your secondary is always faster than reloading... must have been said by somebody who has never had LIEVIQ on their rifle.

(lievik translates to funnel in Slovak - the Q is for style points).
 
LIEVIQ increases your magwell surface area to roughly 200% of its original size, thus giving you a lot more room for error with your reloads.
 
PRO variant fits most MIL-SPEC FORGED lowers with standard magwell profile (as shown in photos, 28mm magwell width). Tested on VFC VR16 GBB, Grand Power, Daniel Defense, Anderson, Nuova Jager, Aero Precision.
 
SIM variant fits most airsoft replicas with a standard magwell profile (as shown in photos, 31mm magwell width).
