Quality materials, design is a bit short.
Fantastic quality made product, however the adjustment for the strap which wraps thru the thumb hole was a bit short on Velcro.. The Velcro was not long enough for it to meet. I ended up just sewing it together right before the area where the Velcro meets. If they added Velcro the full length of the thumb hole strap, this would be a 5 Star product. Comment Added by URBAN-ERT SLINGS, LLC: The Horizontal harnesses are designed specifically for the F/FS2000 manufactured by FN Herstal. The Airsoft Version of this rifle has a longer stock body and therefore will not allow the 2.5" of velcro overlap designed into the harness. The velcro is however only to maintain the excess webbing after adjustment. The male buckle has a webbing tension feature designed into it which is what maintains the adjustment. If you are ordering this kit for an Airsoft version of the real rifle, you can simply install and adjust the horizontal harness and once adjusted, remove the horizontal harness and just hand sew a few loops into the excess webbing of the harness to maintain it's position. So, we are assuming that the 3 stars review was for it not fitting an airsoft rifle.
