My brother purchased a nice single-point sling (I believe it's a Gear Sector?) for me to put on my M4-style carbine. It's got a tension strap that runs down the left-hand side of the rifle (I'm a righty) and then a loop that goes around my body & clips to a sliding point on the tension strap. I have a sling swivel at the 9:00 position at the front of the handguard. What I'm looking for is a decent option for mounting the rear of the tension strap at the end plate. I'd like a quick-disconnect so I can remove the tension strap easily. I've looked through the M4 sling thread & I'm really just looking for a source for a decent rear end plate that I can use with a rear disconnect. THANKS!
