I got a pile of lubricants and cleaners on the back wall of my garage work bench.
I have a tackle box full of brushes, patches, punches, Allen and hex keys.
Baggies full of screws.
I have organizers full of springs, parts, etc., to the point I label each bin to keep it straight.
Point being, old_me nailed it, that’s a great tote type to hold it all, but you’ll just keep building onto it.
I recommend a bore snake for any caliber needed, pistol, rifle, or shotgun.
Some people clean after every trip, some never.. and some, in between.
Bore snake is good for a few pulls through the barrel after a good range trip.
A nice bronze pushrod and handle kit that allows screw on lengths of rod, depending on the firearm, is a good idea.
My advice, get quality here. You can get Amazon Cheapo…but the fittings wear, get loose, etc.
Out of all the cleaning supplies and tools I have, quality bronze fitting and rods are where I went cheap twice…but not the 3rd time.
