Just wondering if anyone knows of a magzine extension that has a built in Laser centered in the tube. I'm thinking something like a 3 rd extension to go with a 20" barrel with the laser built directly into the cap end of the tube. And holding 2rds of ammo. I guess I could make one but its always easier to throw money at a problem. I guess I could maybe buy a 2rd extension and mount the laser in front of it. And slip a nice cover over both the light and the mag ext.
