I just checked mine and I do not have that issue. I would recommend you contact the manufacturer and they will make it right.

Did you call them and ask them what's going on? Any way they could test another new one (in an actual AR57, not bench mode) before sending it to you AGAIN? At least then you'd know if it was a factory thing or your own gun that causing it.

i called and was told to send them pictures i did that and they responded with they had never seen that be for ever. they told me to send it in with the their address. i called and told them im not paying for shipping this was supposed to be brand new item i had never even fired it so they payed for the shipping and also at the same time sent out a new 1 so id have it for x-mas. i dont know whats going on but im not happy for 700 bucks this is BS. i took my dremal and sanded down the high spots it seems functions fine but there's definitely a problem with who ever is doing the machining of the bolts and quality control isn't doing there job either IMO

well got the upper in all looked good so i cleaned it up ran a patch down the barrel oil it then cycled a few rounds and now noticed the necks on the rounds are getting pushed down happened on all three rounds i tried they went from a OAL of 1.5850" to a OAL of 1.5730" so there chambers are also out of spec. the last upper also had this issue i didn't notice until i went to measure some rounds. i contacted them again this will be the 4th upper there going to send and i have the feeling it will be the same way because all the uppers they have sent have looked the same with a round loaded into it i am uploading 2 pics so you can see. now if you look at the picture you can see that the bolt is not contacting the barrel so my thinking is the round is getting slammed into the barrel and it's causing the bottle neck to get pushed into the case causing the shortened round. what do you guys think?

You've been more than patient...I'd send this back and demand that my money be refunded. It's pretty clear they're currently unable to perform proper QC on their products and there's no reason to risk injury from their products.

What manufacturer is this? I'm in the market for an AR57 upper and would like to avoid these guys!

You have shown admirable restraint by not flaming the manufacturer. Politely ask for a refund.

I honestly would rather my money back but I didnt buy the upper from ar57 directly I bought it from lone wolf not sure how that would work. This upper is the only ar57 brand that I know of from 57center

well received a call from jeff at ar57 HQ and he personally fired and checked out the upper hes sending me. hopefully this will be it and all issues fixed. i did send those pictures to him and he said the bolt is not supposed to contact the barrel why i don't know doesn't make sense to me. he also said the tolerances look good but he couldn't tell without it being in his hands. hopefully this is it if i have any probs with this upper im going to ask for a refund and ill use that money to finish the 308 I'm building.

Well, having been on the fabrication side of things at one time, I can attest that things can and do go sideways despite all good intentions. At least they appear to want to make it right. Good luck.

When I bought mine, I went directly to their office. I live about 2 hours from their shop. They made a point to say if I ever had any issue to call or bring it in and they would make it right. I am glad that they have shown you this much help. It shows that they are truly concerned for their product and care for the consumer even though you had bought it from another distributer.

heres a couple pics of the rounds 2 left ones have been chambered and the 1 right round has not. i think the weight of the bolt and the spring pushing it foreword and nothing to stop the bolt its just ramming the round into the barrel messing it up iv had a couple pieces when extracted they had the bullet fall off. you all might want to check your uppers and see if this is happening the change in the brass could cause it to be over pressured.

If those compressed cases had fired you would have had a shrapnel grenade go off inches from your face.

i received another replacement upper today and unfortunately its doing the something to the brass so i sent an email and asked for a refund but i don't know how that's going to go sense i bought it through lone wolf dist. if i was all of you id check your brass im willing to bet all the uppers do it sense the bolt has no way of stopping its relying on the soft piece of brass to stop it. the brass on these uppers is getting push to far into the chamber re shaping/sizing it.

Gents,

From the looks of the brass I'd say the upper was short chambered...due to the shoulder pushed back the way it is...

Definitely NOT kosher...

You could clean it up and see if it continues to do the same thing...

Yeah still having issues I cleaned everything up as soon as I recieved it. I still have gotten no response from the office about a refund its been 2 months sense all this started. Today I decided to send a email to the tech I was dealing with to see what he had to say. I'm very disappointed with this company and lack of CS which was good in the beginning. If your looking at a 57 upper save your money build something worth 700 bucks or drop a 22 conversion into your 556. BBB might be the next step if I don't get any response.

Your brass is being compressed because you are trying to force the bolt to meet the face of the chamber. They were not designed to operate flush like a normal rifle. If Jeff tested it then it works fine.

Generation 1 or 2 upper? I'd guess Gen 2. My Gen 1 seems just fine. I can't even see how the bolt would mark the barrel face that way, even if the bolt was in upside down. No compressed cases here.

gen 2 and the issue with the bolt is it wasn't completely flat the indents where high spots around the bolt face. the compressed case issue is another problem idk why its doing it iv checked everything. pretty sure its a chamber issue as they had a bunch of bad ones awhile ago they do not cut there barrels they only "glue" them in place according to jeff when we last spoke.

Glued barrels? I recently was in contact with Jeff when my barrel came loose while removing the muzzle device. I was concerned about head spacing, but he said as long as the bolt closed against the barrel and not the receiver, I was ok. 50 ft/lbs and red Loctite.

You shouldn't have to, but milling the bolt face flat should be easy enough. But a bad cut on the chamber? Way not cool.

milling the bolt face would be easy but it had already done damage to the barrel face, it shouldn't have ever left the shop that way IMO. QC is poor IMO he said they put 1 bullet down range to function test and that's it as long as it goes bang and not boom it goes out the door. yeah he said glue but meant loctite im sure. they got a little happy with the loctite on one upper i had received PITA to clean up

Hello,

Has this issue ever been resolved??

I have just received a GEN-2 AR-57 upper via Lone Wolf but had trouble installing it. Similar to the picture above, my barrel extends into the receiver. The result is that it pushes the bolt back beyond the end of the upper receiver by about 1/8th inches and prevents it from closing down on the lower receiver.

The assembly arrived with the both the barrel and muzzle device only hand tightened. My initial thought was that there must be some kind of barrel shim or lock washer missing which would lock the barrel at the correct depth. Can anyone advise?

Thank you

My barrel came out when trying to remove the muzzle device. On inquiry, I was assured there was no headspacing necessary. I torqued it down and it runs fine. It protrudes thru the upper as much as 1/16".

My issue was never resolved they stopped responding to my emails after the last batch of pictures I sent them of my compressed cases and told them there out of spec chambers could seriously hurt someone. Try giving them a call/email.

I emailed AR57.com and got an answer from Dennis who said that:
  • 1. The barrel is supposed to protrude into the receiver as pictured.
  • 2. The barrel should be tightened to 60 ft. lbs. and no further headspacing is necessary.
But I can't close the the receiver with the bolt sticking out as much as it does. I tried this with a few Bushmaster and Rock River lowers without success. Below are pictures of how much it sticks out and the fitment with the lower receiver:

Can I ask you guys to measure the length of your AR57 bolts?

Mine appears to be just over 6.75" in length.
