very comfortable as is. I personally love how adaptable it is as I run an mp7 and often switch from that to an m4 platform. Using the buckle feature with the mk3 micro rig is just a bonus. this jpc is very well made and holds the weight on my rig which include 4 mags Allen key knife glow sticks pistole mags, it doesn't bend fold or loses its shape. thanks again airsoft depot for selling amazing products.
