Just got an Armalite M15a4c.   I was thinking of mounting a small light on the carry handle, posssibly even a light/laser combo.  Haven't seen that on anyone's rig yet, so I was wondering if anyone out there has done it.  I basically don't wanna block my bayonet lug. I know command arms has a nice mount for the lug, but I wanna keep it open. Elzetta makes a nice mount too, but it covers the lug too.

If you check Cheaperthandirt.com they make picatinny rails that mounts to the FSB to allow for laser/light mounts.  You could also mount a single rail to the bottom of the lower hand guard and then mount a CAA FGA or what ever you choose to do there.  Also at www.cheaperthandirt.com  Or get a railed forend and ditch the stock handguards all together.  I'm sure other members have better solutions or better ways of doing things.
