"If you're looking for a bare-bones chest rig, just to hold your magazines, and maybe a grenade, then this is for you. I'm 6'3" and 190 lbs, and this fits me beautifully. The split harness design doesn't dig into my neck and makes it wearable for long periods of time. Six KWA 120 rd. midcaps (1 in the gun) are more than enough for most games, and the extra pouch holds my Tornado Impact grenade. I run the Tippmann M4, I wear a hydration carrier on top of this with my HPA tank and I retain my range of motion and mobility. Reinserting mags takes little time and the chance of mags slipping out is slim to none. The whole interior of the chest rig is accessible by opening the Velcro on the top and I find it helpful to carry my phone, some bills, and maybe a bag of BBs, along with anything reasonably flat that will fit into it. You can stick your moral patches, flags, name tapes, whatever on the Velcro section on the back connecting strap. When in storage or transport, it rolls up to about the size of a water bottle. Compared to the Blue Force Gear similar chest rig, this is a more affordable alternative if you don't feel like shelling out 90 dollars. In combination with a battle belt, you can add your pistol mag pouches, dump pouches, or whatever you can't fit on this chest rig. Overall, if you like having lightweight kit a minimalist feel and adaptability, then this may be for you.
Pros: simple, good retention, affordable, lightweight, compact, works with HPA rigs
Cons: may not fit large frames, limited capacity, no MOLLE/PALS
"this is a very nice no frills chest harness, good buy for the cost
you can fit two M4 mags if you force it in the pouches (I own the BlackHawk version of this vest and it fits 2 magazines a lot better)
and any G36 users, you can fit one mag very nicely
the biggest con for this vest,
I am 6 foot, 250lbs, the vest sits high on me with the straps as loose as they can go, built for smaller frames (easy fix to this is taking it to someone with a sewing machine and replacing stock webbing with longer piece to fit you better.)
this is a good buy for a simple rifle shooter chest harness, if your a large framed player, this will not fit easily on you without the modification I mentioned.
