Description
Keeping a .270, .280, or 7mm rifle running clean does not need to be a production. The DAC Technologies GunMaster 12-piece kit gives you the core tools for routine bore care and packs them into a molded clamshell case that stays organized whether it lives on the workbench or rides along on a hunt. It is the kind of no-frills setup that earns its keep after a long range session or the tail end of a season in the field.
What Makes the GunMaster Kit Easy to Live With
The heart of this kit is the 32-inch pull cord rod. Instead of pushing a stiff rod down the barrel, you run the cord through and pull your brush, mop, or patch from breech to muzzle. That approach sidesteps the sticking and bent-rod headaches that come with cheap push rods, and it keeps hardware from banging around the crown. The multi-function handle ties it all together, working with the pull cord, accepting the cleaning tips, and doubling as a screwdriver handle for the included bits.
Tools Built for .270, .280, and 7mm Bores
Inside you get a phosphor bronze bore brush to scrub out fouling, a mop for laying down solvent or a final swipe of oil, and a slotted plastic tip that grabs a patch and drags it through clean. Twenty-five cleaning patches give you plenty of cycles before you need to restock. The bronze bristles are chosen to cut carbon and copper without being hard on the steel of your barrel.
A Kit That Pulls Double Duty at the Range
The six-piece driver bit set is the sleeper feature here. Loose scope rings, a wandering base screw, or a sight that needs a nudge can all be handled on the spot with the flat, Phillips, star, and hex bits. Pair it with the compact case and you have a maintenance kit that covers both bore cleaning and the small hardware fixes that pop up when you are away from home.

Frequently Asked Questions
What calibers does this GunMaster kit cover?
This kit is set up for .270, .280, and 7mm rifles, since those calibers share a bore size close enough to use the same brush, mop, and tip. If you shoot any of those three, this is the right kit for the job. For other bores like .22 or .30, DAC offers separate GunMaster kits sized to match.
How does the pull-through cleaning work on this kit?
Instead of a rigid push rod, you feed the 32-inch pull cord through the barrel and draw your brush, mop, or patch from the chamber end out through the muzzle. This helps you avoid sticking, bent rods, and wear on the crown that can come from cheap push rods. It is a simple, effective method that works well for quick field and range cleaning.
Can I use the driver bits for scope or sight work?
Yes. The six-piece bit set includes Phillips, flat head, star, and hex bits that snap into the multi-function handle, so you can tighten scope rings, base screws, or sight hardware on the spot. It is meant for basic adjustments rather than heavy gunsmithing, but it handles the small fixes that come up at the range.
Is this kit small enough to keep in a range bag?
It is. Everything nests into a compact molded clamshell case that latches shut, so patches and bits stay put during transport. It slides easily into a range bag, duty bag, or truck console for maintenance wherever you happen to be.
