Fits MK-4 cans
"The pouch is great construction & quality, but the flap is a little short for an MK-4 can. It still closes, but if the flap was another half inch or so in length the Velcro would have that much more bite. For some reason options for OC MOLLE pouches is slim even with the abundance of agencies switching to outer vest. I am sure that I have tried all the brands on the market dedicated for OC. Spectar Gear, ProTech, Condor, and now Propper. The Propper one is at the top of the list. I do like the ProTeck one better, but the 2-4 month wait for one takes it towards the bottom of list. Note: The Condor one is at the bottom. It does the job, but does not hold up over time."
