I like the Magpul MS3. 2 point QD and if you're not an idiot you can detach the rear and secure the adjusting portion to your shooting arm and use it to help stabilize the rifle.
Guess I'm planning on using the RPR this year for deer and need a QD 2 pt sling.
Anyone have experience with these? I'm a traditional sling guy. Assuming 1.25" push button mounts is universal?
