AR-15 | Cleaning

Just got a CMMG AR with a Romeo + Juliet combo scope/laser. Sighted it in and just cleaned it. I’ve always just used Hoopes on my shotguns. I used it with the AR after taking it apart. Any issue with this or would someone recommend using another cleaner?
I also had trouble getting the rod + cleaning cloth down the barrel. Purchased a bore snake like I have with shotguns instead.

We used Break Free CLP in the military 40+ years ago. I still use it now, cleans, lubes, protects, haven’t had any issues…

Get a quart of quality 5w 30 motor oil. It's made to handle more extreme conditions than anything your rifle will see and has plenty of detergents to clean carbon buildup. A bottle of Hoppes is good to have for any stubborn spots.

I run gun butter on my bolt carrier and bolt and dab a little on trigger springs. A little goes a long way.

Pretty sure CLP is still the mil standard.

I just spray some Rem Oil in the action and a few swabs through the barrel.

Dedicated gun oils have more of what is actually needed, motor oils don't do as well with gun residues which often contain lead and copper compounds.

Ever hear of leaded gasoline? My point is that engines sustain far more abuse than your typical semi auto rifle, so not that much is going into the latest and greatest gun lube and cleaner to justify the difference in cost per volume. Hell, I remember some company claiming they had the next best gun lube and cleaner, which turned out to be nothing but a very common industrial grade oil; aka Canola oil. It worked well, but the mark-up was insane, like most gun oils and cleaners.

Honestly, I clean about 2 guns a week and a $15 bottle of CLP will last me a year. Price typically isn't a concern.
For AR cleaning, you guys have any good tips for specified tools? I've recently bought some chamber cleaning tools off Amazon. Always a pain to get in there. Not sure how well they'll work as I've not used them yet. Additionally, I've seen mixed reviews on bolt carbon scraping tools. I typically just soak in Hoppe's and brush with a brass bristle brush and remove what I can as I've read scrapers will prematurely reduce the life of the bolt.

Its all you need.
They'll sell you as much equipment and products as you'll buy, but to maintain a rifle you just need a simple kit and some CLP, maybe a little grease for bearing surfaces.

I use a bore snake as well, but it doesn't clean out the area where to bolt locks in. I shoot suppressed, so it get's dirty in that area. Hasn't caused any issues, but sometimes I just get anal and when a q-tip keeps coming out pitch black, I wonder if there's something that could at least help put a dent in cleaning it a bit.

Brake parts cleaner.

It needs to non-chlorinated brake cleaner. I'm not a fan of the 3:1 cleaner, lube. ect.
I use a bore snake to clean the barrel. To clean the upper, lower, and bcg, I use the non-chlorinated brake cleaner. After that, I will use a lube on the bcg. After 15k rounds my ARs have never skipped a beat. I use Lucas products for lube.
I usually don't clean my ARs until 1k rounds are fired thru it. Just make sure the BCG has plenty of lube

Yeah, for race cars and maybe some older aviation fuel blends these days. Last time I bought race gas it was Sunoco 104 unleaded though. Modern everyday motor oils are not formulated to deal with lead compounds and are actually designed not to attack copper compounds either as copper/bronze alloys are still used in bearings and guides.

Do you have any research that quantifies that? I look at a lot of military small-arms research, especially stuff that applies to how they test and look for better CLP's and I don't think you really know how much abuse is going on with these things which is why gun lubricants are formulated to handle much higher temperatures than typical motor oils as well as higher concentrations of EP additives. Cost per volume? I bought a gallon jug of Breakfree CLP for $68 a long time ago, it will last probably me another two decades so cost-per-unit-volume is pretty much a non-issue if you are using the stuff properly.

Yeah, several companies put out similar products because the military put out a request for a biodegradable product to replace CLP years ago. There are plenty of synthetic oils derived from non-petroleum products that do offer great performance, and some of those compounds get formulated into motor oils too. Also, there are gun oils that use mostly deoderized kerosene and mix in alcohols and citrus oils so the marketing wank isn't just limited to those that use vegetable oils and one of the best products for corrosion protection uses sheep grease (lanolin). The Army tests commercial off-the-shelf (COTS) products all the time, have been for decades, and they still use BreakFree CLP because nothing has proved better for the cost. If a motor oil could meet the specs then I'm sure they'd rather repackage it and save the money but MIL-PRF-63460D is a damned tough standard to pass and even BF CLP doesn't pass all of them.
