Your trusty Hi-Point carbine is a bullet-eating, lead-spewing machine that will cycle box after box of ammunition until the cows come home. All this firing can lead to mounds of empty 9mm, 40 or .45ACP fired brass to pick up. Sounds like a rich man's problem, but a brass catcher can help if you need one.
Why a brass catcher?
Many shooters simply fire their rounds, examine their targets, and walk away when they are done shooting. However many ranges require that shooters police up their spent rounds by picking up their brass. Brass rolling around underfoot in concrete or paved areas is a safety hazard. On dirt and grass ranges, this can lead to projectiles being sent screaming when lawn care is done. Once trampled into the soil, brass corrosion on a massive scale can lead to ground water issues. For several reasons, it's important to pick up spent brass.
This can be a time consuming process involving rakes, shovels, brooms, and the good old-fashioned stoop-and-pick method if lacking the above tools. However, the simple brass catcher mounted on the side of the firearm and as its name implies, collects those ejected rounds before they ever hit the ground.
For those who reload, this also helps keep that spent brass both nice and clean while eliminating the possibility of cases being squashed underfoot and bent by bootheels.
The UTG catcher
One the kings of the aftermarket supply distributors, UTG, offers what they bill as their Deluxe Mesh Trap Shell Catcher. It has a steel-framed box opening that is covered with a mesh type of material to keep weight low. The design fits around the receiver with the use of Velcro straps and is lightweight at less than 4-ounces. These run for anywhere from $6-10 and can be had on eBay, Amazon, Midway and other outlets fairly quickly so shop around for the best deal.
These are marketed mainly to AR-15 rifle owners but they will work with the Hi-Point 995/4095/4595 series. The generic design makes it a requirement that you play around with the catcher to get it to fit your carbine and it has been noted that the bag is rather shallow, requiring dumping after a couple magazines. Still, for $6....
Make your own
If you or someone you are close to is handy with a sewing machine, a brass catcher may be just 15 minutes worth of work away from you. All you need is a bag sewn out of virtually any cloth that won't melt or catch on fire from hot brass (avoid polyesters) and a way to hold it onto the firearm.
Canvas or athletic netting is very popular for these projects as are old BDUs-- after all you just require a little material. The band can be leather, canvas, Velcro, paracord, or elastic. Some enterprising Forum members have even made scratch-build brass catchers that mount to the rifle using rare earth magnets; a method that forgoes any straps.
Of course, you can always just spread out a tarp, but hey, to each their own.
