$2500 AR, WHAT AMMO is ok/not ok?

[hatidua]

Im referring to the fact that when DI rifles get really dirty, they will start to jam. I do not have any experience with the AR or DI platform, so all i know is what i read, but this is a known issue with the DI system. M4's jamming in Iraq, Afghanistan etc.

That's rich

Buy my XCR for half that price and shoot anything you want out of it!

Well AR's appear to be put together with ball peen hammers (center left), so pretty much anything should fit in the chamber if you hammer it hard enough

Her main tool appears in center left as a ball peen hammer

I would very much like to see anyone put together a complete AR with all the roll pins involved without a ball peen hammer!

^ I'll make a video. Lol.

Does pliers and screw driver count? As long as I'm not using ball hammer right??

EDIT- UGH. MY f'ing head is going to explode. Just went on ammoman.com and wholey cow....so many options. More options than building the damn gun itself.

Yes, way too many for a newb like me... So I'm just waiting for the gun show this weekend to buy bulk 1000rds of something, Federal if they have those.

cheap ammo....

this can happen to any firearm


cheap ammo can squib in a barrel, then the next round fired turns the gun into a grenade.

I hope that the person who shot that is ok.

I guess a claw hammer is ok!

You want to avoid laquered covered ammo. A lot of the cheap russian stuff does this. It gums up your barrel and you'll never it out of there. It can even damage your barrel.

That is why I always laugh at the AK guys who swear "their AK can fire anything". Sure, so can an AR, it is that it is really dumb to do so in both that they completely miss. The really cheap stuff will jack up any barrel, regardless of what it is attached to.

How would a coating on a casing get inside the barrel? In actuality the steel case expands less than brass, so you get more residue/gunk in the action than you would with brass, has nothing to do with the lacquer

Again how will cheap ammo "jack up" a barrel, compared to expensive ammo?

Only thing I shoot for fun out of all my guns is brown/silver bear now, even my somewhat pricey AR. No problems period, not a single bad round.

Round counts with this ammo are approx:
AR-15 - 450
Glock 26 - 2000
Glock 17C - 200
Saiga 7.62x39 - 3800
M91/30 - 200

Im not the person you quoted but ill answer the question anyways. Laquer cased ammo heats up the the point where the laquer begins sticking in the chamber. The chamber is part of the barrel technically as it is all one piece. After a while that laquer builds up in the chamber. Let it cool and it hardens in the chamber. Then run more ammo, either steel or brass and it will get hot again and pretty soon the laquer gets soft enough to stick to the new rounds getting chambered until you get one stuck and the extractor rips the rim off. Then go though the hassle of getting the case unstuck and it will have a layer of hard blackish laquer stuck to it. Been there, done that, and have seen it with others many times. Laquered cases arent that common anymore though so its pretty much a non-issue.

My advice is to stick to American made factory ammo regardless of what you have. I have never had any trouble Federal or Winchster. I have not tried rifle ammo from Magtec or PMC, but I have had great success with their handgun ammo. There are also some extremely expensive match grade ammo companies that I have not tried because they are too rich for my blood.

While I normally avoid foreign ammo there is a Czech company called Seller & Bellot that I have used with great success. Never had any issues with their .223 in my AR.

Fiochi has been hit and miss with me. Wolf I would not touch for anything.

I do not shoot reloads. I did not reload them so I cannot trust them. 99.99999999% of the time when a gun exploads a bad reload was to blame. It is one thing to reload your own ammo and know what you are doing. It is completely another to trust some stranger. How much is your hand and face worth? Is disfigurement worth the few cents you saved?

Stick with factory ammo from a brand you can trust.

There is a lot of FUD here. The lacquer from steel cased ammo does not gum up barrels; that is nothing but a myth. And as for reloads, I would agree that it is a good idea to avoid any reloads from people that you don't know, but factory reloads are pretty much the same as new ammo; they come from licensed ammo manufacturers and the only difference between their ammo and "new" ammo is that the brass has been fired once before.

More nonsense. Take a spent lacquered steel case, heat it with a torch and tell me if the lacquer melted off.

i have one of those expensive ar's. maybe two of them. i shot seller and bellot. zero issues on them on different mags (pmag and some steel or Al ones). Wally world federal bulk back. no issues. bulk ammo from sportsman guide (can't recall which but the 1K ones); no issues. black hills and federal gold match. love it. i think i also have some prv partisan 62 gr or something like that.

i've not tried wolf/steel casings.

Magtech is from Brazil and PMC is from Korea. FYI.

Brass, Steel, my AR shoots it all. . . . . .

I went back and did some more reading on failure to extract issues, and wolf ammo. Here are a couple links to threads, hope it's ok to mention other forums in here:

From what I gather maybe some guns have chambers that are too small, maybe they heat up and expand during use, then a round gets stuck and as it cools becomes even more tightly stuck. Edit: extractor springs and gas port sizes may also factor into the problem.
I wonder if some or all? of the black on them is normal carbon buildup being pulled out due to being stuck or oil and penetrant washed down the barrel as part of the extraction efforts.
This seems to be mostly an issue with some ARs. As other people have commented they've run many thousands of rounds with no problems whatsoever.
I like AK's, cheaper and don't have that problem. Beauty is in the eye of the beholder.
