I have a recently purchased BCM SOCOM Carbine Gas 16 inch upper. I put the magpul handguard on there but I'm looking for a solution to mount my sling. Being carbine gas there is only so much space to grip the hand guard so I was trying to avoid mouting the sling there. I wanted a Colt side sling mount that used to come on the M4's but they are esspensive and hard to find. I am currently just using the bottom sling mount with some paracord attached and that seems to do OK but was looking for a better option. Does anybody have any suggestions?
