We have found this a regular question from customers, “how can I attach a sling to my XCR”?
Depending on the age of your rifle and what buttstock/stock adapter you have installed, there are a few options.
Original ACE Stock
This stock has a loop on the back of the receiver designed to install an HK style snap hook. This would be ideal to 1) use a single point sling or 2) use a 2 point carry sling.
1913 Rail Mount Front Attachment Point: Daniel Defense
Single Point Sling: Specter Gear
Newer model ACE Stock
This rifle has a hole in the top of the receiver designed to install a push button sling swivel. Ideal for using a single point sling.
Push Button Sling Swivel: Daniel Defense
NEW FAST Stock
The new Fully Adjustable Stock also has a hole on the bottom of the stock designed to install a push button sling swivel. This is designed to use a single point sling also.
NEA Stock Adapter
If you are using an NEA stock adapter on your rifle you will have additional mounting points for push button swivels.
DLASK Stock Adapter
Dlask XCR M15 Stock Adapter
Dlask XCR Ambi Sling Plate
If you are using a DLASK stock adapter there is an ambi sling plate which can be used in conjunction with the adapter. This will give you a loop which you can attach an HK style snap hook.
Hope this helps!
