If you want to turn your AR pistol into a rifle, all you need to do is add a 16 barreled upper and a stock. Just make sure that if you return it to pistol configuration that you detach the stock first and an forward vertical grips you may have attached to the weapon...f the firearm was already classed as a pistol with a barrel shorter than 16 inches, it cannot be converted to a short barrel rifle and legally registered. An AR15 pistol can be rebuilt as a legal length 16 barrel rifle at a later date, but not as a legal short barrel rifle of less than 16 inches.
Step 4. Add one or two handfuls of garden soil or finished compost to the tumbler (see References 3). Garden soil or finished compost adds beneficial bacteria that helps start the decomposition process.
You have less of a chance of smothering the lawn. You may want to use Â¼-inch mesh hardware cloth. One way to incorporate the compost is to aerate the sod, then apply a 1/8-inch to Â¼-inch covering of fine compost. Use a rake to distribute the compost into the crevices.
