it is better than an ugly bulky quad rail,not as perfect as it sounds, if you have a big hand you may no have enough space on the hand guard. i don't trust the strength of the attachment. so i don't think it is suitable for vertical grip and or for a sling attachment. It will be good for a simple flash light or other attachment that does not require accuracy and precision
Pros: good alternative for quad rail
Cons: it fits, not a perfect fit though
