New to the forum and to AR's. Just got back from the range with my PSA 16" and I cleaned it but have some questions. I have Dewey rod (22-26 cal) and I ordered brushes for it. The brushes are 20cal, 5/40 thread. Even with the adapter that came with the rod I could not get my brushes to fit.
1. Does Dewey sell another adapter to make their own brushes fit the rod?

I just ran patches through it, will it be fine to let it sit until I can get the adapter to brush out the barrel? Only put about 60-75 rounds through it at the range.
2. I have some generic patches (2" round) that work well on my Mosin, but were too big for the 5.56. I just tore them in half and that seemed to work. What size patch should I be using instead? 1x1?
3. When I disassembled the rifle the parts had a pretty thick coat of black lube, is this assembly lube from PSA? Was decently thicker than the CLP I replaced it with.
Thank you!
i bought a bulk pack of 1000 .22 patches from brownells. also bought the nickel coated tipton .22 jag. the first patch is usually tight, but they work great!!
the threads are 8/32 as stated before, at least on my tipton carbon rod.
i RARELY run brushes down my barrels. i've never really noticed enough buildup to justify it. YMMV depending on ammo used and quantity of ammo used

Thanks guys. I guess I just need to order some smaller patches. I don't think the barrel was really dirty after shooting but I thought I might have seen a spot or two while looking down the barrel and I wanted to brush it out, could have just been a shadow I guess.
One more question...
After cleaning everything I did a function check. With no magazine, if I pull the charging handle back it will slam home as normal. If I load an empty mag, the bolt doesn't slide forward unless I use the release. I assume this is how it's supposed to work, I just don't recall if it did it yesterday at the range. Is a part of the magazine triggering something to keep the bolt from closing when it's empty? Does that part not come into contact with whatever it's touching when there are rounds in the magazine? Thank you

The bolt is supposed to lock to the rear with an empty mag inserted. The mag follower pushes up on the bolt catch to engage it.
Thanks. Guess I need to look at some parts diagrams to see how the follower and bolt catch fit together.
If you want to see how it works firsthand, just remove your upper receiver and insert an empty mag into the magwell. You will be able to see where the follower pushes up on the bolt catch.
