QR Sling Swivels & CTR?

[wahoo95]

I notice a lot of pics on this site with Slings attached to QR Swivels on CTR Buttstocks. Where can I get the proper QR swivel to attach to my CTR...and does anyone have the product code?

DD, KAC etc make them.

Grant sells a version of the VCAS with them built in.

Vltor and Blue Force Gear also makes heavy duty QD swivels.

I'm using Vltor QD swivel on my CTR which I got from Bravo Co. USA.
