The AR-15 is a semi-automatic rifle that fires the .223 Remington round. Shooters can go through a lot of ammunition in a range session, and many hunters and shooters enjoy reloading their own ammunition. If you're tired of picking empty shell casings off the ground, consider building a brass catcher to set up alongside your rifle while you're shooting. Construction is simple, and the supplies typically cost less than £16.
Bolt the lengths of aluminium together, making a square frame. Drill through and fasten each end to another, forming right angles. The aluminium strips should be at least 14 inches long so that the brass catcher is large enough to catch casings as they eject from your rifle.
Fasten the frame to the spring-balanced lamp arm. Pre-drill the holes, then use more bolts and nuts to fasten the end of the arm to the bottom of the frame. Attaching the arm allows the shooter to adjust the height of the brass catcher.
Attach the snaps around the mouth of the bag. Some snaps require a slit in the canvas to mount them. Place the top portion of each snap so that it will fold down inside the bag and snap to the lower portion on the inside of the bag. The size of your canvas bag will determine how many casings you can hold before you have to empty your catcher.
Snap the canvas bag onto the frame. Cut four slits in the canvas, one at each corner of the frame. This will allow the bag to fold and snap around the frame. Prop the frame up so that spent brass casings will eject through the frame, into the canvas bag.
Mount the brass catcher. The old lamp stand arm will probably not hold the awkward weight of the brass catcher on its own. Either attach a weight to the bottom of the arm, or drill out holes so that the catcher can be bolted to a table or other surface when you are shooting. Now you have a firm, adjustable brass catcher.
When handling any firearm, always be sure the gun is unloaded, and follow all universal gun safety rules.
