Butt pad on carbine mod?

I ordered one and I'd like to sugjest ya'll add a pair of Velcro straps over the mag pockets to keep them more secure, I've found in mine after only a day of owning it that the mags, if you are not careful, can slide out and hit the ground. I'll be sewing a pair of cheap simple straps of some sort onto mine. Maybe one that buttons down, which ever is cheapest... but I hope someone there at the factory reads these and just gives it some thought...
