I'm not a high volume shooter like some of you folks. My AR's generally don't shoot more than 300-500 rounds each in a day - and that's limited to when the kids/grandkids are here! They do get hot in a hurry, but I never have problems with ftf/fte's, and cleaning is always easy using the old school type stuff that I have used on my other guns for the last 40-50 years.

But, I do tend to run mine wetter than what a lot of folks suggest.

I was instructed to oil just a few points or places on an AR, and to leave the rest alone.

The Mobil One synthetic oil is definitely a winner, it is great on firearms. Mixing a little tranny fluid with it will thin it down a bit, make it penetrate a little better. - I use it as it comes, it has a lot of staying power and will not dry up so quickly as a lot of the other oils.

I tried using dry-moly lube on my AR, it seemed to work OK but is messy if you get any of it on you. I never tested it with a lot of rounds though, I always shot mine deliberately, like a rifle.

You don't shoot much, do you?

I think so many of you are missing the suppressor factor. They significantly increase carbon deposits into the action. Fire one round from a clean action and bolt, with a suppressor, and the carbon build up on the top two rounds in the Mag is pretty heavy. That is an indication of how much junk gets into the action with a suppressed AR.

Did you put bad mojo on another AR? You are the Schleprock of ARs. Must be a left hand thing.

IMHO, there is nothing special about cleaning an AR bolt. Dissemble the BCG and use your M-Pro 7 to clean. Re oil with a good gun oil (liberally inside the BCG) and you should be good to go. No snake oil is needed.

Kyle and I may need to perform an exorcism on your rifle is this continues...

Mine has not broke down, but it did get sticky to clear the action. Two hands on the charging handle and the butt stock on my toe, sticky. That was yesterday evening. Cleaned and oiled this morning and the rifle ran fine this afternoon.

Once or twice a week, weather permitting.

It is true that I have never been a big 'spray and pray' fan, I get my kicks shooting groups, a paper-puncher.

Lol Jason is the crux of AR's. I shot mine all day long without failure let him shot it one time and it fails to feed lol.

Yes, a suppressor is basically a muffler - and produces some back-pressure as all effective mufflers tend to do.

I've decided to treat them like the mustang in the pasture. We will come to an understanding, and live in peace.

Haha

I think you are missing the reason for a piston system.

I'm not missing it. You are missing the fact that I already own a direct impingement rifle that I got a fair price on, and have already developed a hand load for. All it needed was a trigger, which it got today, and all it will need in the future is oil. Which I always have in the truck, in the hunting pack, or in the shop.

Do you have an adjustable gas block? I can imagine how much extra carbon you have to deal with using a suppressor.

Not yet. Joe Bob's was all out, and Midway was low on choices yesterday. I found a clamp on, and may have to go that route. It's ejecting at 2 o'clock, so I am getting too much gas into the chamber.

Bingo.

Hope you are buying Syrac, only one that stays where you set it

Syrac is the brand that is in stock. I was little concerned about a clamp on, but thought it was worth a try.

They are the only one I found that has detents for each setting, the other have nothing to keep them from backing out, making you continuously adjust it. I highly recommend spending the little extra for the Syrac or put clear fingernail polish behind the adjustment screw

Good to know. I also read that it is adjusted from the front. I can't understand why there would be any other design, with as many free float tubes people are running.

I have one syrac gen II, and 2 SLR sentry. I like both so far, the SLR are very nice with click detents in between each setting. I've read the SLR have good customer service and you can disassemble the little leaf spring detent and clean out the carbon if you need to, though I haven't had to do anything to any of mine yet.

As far as clamp on, I like them. You don't have to worry about set screw dimples, and I don't see having trouble with it moving, especially if the block is under your handguard. I had a WOA barrel cerakoted black, and believe it or not the thickness of the coating made it so that the set screw block would be way tight going back on. So I bought my first SLR clamp on.

Good info.

Jason I got my Joe bobs dialed in last time I was at the range. It does suck to have to take the rail off to tune it, but I'm only tuning it once. This one has a set screw and then it has brass screw you screw into the steel screw locking it down. I don't see it going any where but haven't gotten to shoot it enough to really know.

That was then, this is now.

I love my black guns and so do my 3 girls. I have a good friend on this forum that's still active duty, 2 tours in Iraq and Afghanistan and he bought and built his own AR. What does that tell you about the guns now?

Agreed. Having carried one for 20 years now (currently in Afghanistan), I own a few. To be sure, the first M16s were problematic to say the least. But as far back as the 90s, the only malfunctions I saw first-hand were magazine induced (usually worn feed lips), or a result of using blanks. But I think some folks need to join us in the 21st Century.

Video here, NSFW due to language, but it's a pretty telling example.
