Adam, since the SCAR already has the OEM rear sling mount (the hole) you don't necessarily need another sling mount for the rear of the rifle. For the front of the rifle it is very helpful to have a QD sling mount such as our Picatinny Rail Sling Mount (http://www.tacticallink.com/Picatinny_Rail_Sling_Mount.html) when using a convertible sling. Another sling mount to consider for the front of the rifle is this one: http://www.tacticallink.com/Kinetic-Development-Group-Front-Ambi-QD-Sling-Mount-For-SCAR-Rifles-SQP5-110.html
Thanks for the inquiry.
