Push Button QD Sling Swivel by Blue Force Gear
The Push Button QD Sling Swivel provides a secure, quiet sling attachment point and allows slings to be quickly removed and installed on multiple weapons.  The Push Button Sling Swivel can be threaded onto any Vickers Slings. 
 
Designed to be Stronger and Lighter
The smaller swivel body and push button reduce weight while minimizing the chance of accidentally disengaging the swivel. A larger gauge sling loop gives increased strength and durability. The Push Button Quick Detach Sling Swivel has a matte phosphate finish for corrosion resistance and signature reduction.
 
Fits all common quick detach (QD Swivel) sockets
The Push Button Sling Swivels fit all common quick detach (QD Swivel) sockets found on some buttstocks, forends, rails, or aftermarket socket adapters.  Ensure that your weapon has a QD socket to correctly attach the sling to the weapon.  For attaching a Push Button Sling Swivel to railed forends without integral QD sockets, you can use the Rail Mounted Push Button Swivel Socket.
 
Choosing between 1" and 1.25" loops
1" Swivels can be used on any Vickers Sling that has 1.25" webbing. The 1" loop keeps the Swivel more stationary on the sling.
1.25" Swivels can also be used on any Vickers Sling but allows for more movement of the webbing than the 1" Swivels.
