    I recently picked up a real M24 from a contractor (my baby is back!) The only problem is that he threaded the barrel for a can.... I have no need for this (threaded barrel) so I need opinions of which barrel to go with. I was thinking an Obermyer or Mike Rock (possibly a Adavance Barrel System carbon composite barrel) or just going to GA percision.... I wish I could buy a barrel from Remmington ( I want nothing more than a 100% correct M24), but thats not a possibility.

    Feel free to voice any of your opinions. Looking for some help.

    Here's ABS website...http://home.windstream.net/mdegerness/prod03.htm

    I like what I see

    Being that GAP is making M24 Spec rifles, now might be a good time to ask if they'll help you out.

    That's where I'd be headed first stop

    If you want the gun to spec. Without the threads period. I would look to GAP as well.

    Isn't Boots Working with Rock now? I don't remember where I heard that...Maybe I'm retarded, but someone "in the know" said it. Point is that either is about the same. I would have GAP put a Rock barrel on it. Good luck.

    So it sounds like Mike rock and the labor done by GAP would be the best bet.... Thanks for all your opinions.

    I'll shoot em a call and see what their lead time is... for now I'll have a local smith make a thread protector.

    Thanks again,

    Try and find a barrel from Remington for a MilSpec 5R. They are M24 leftover/overrun barrels.

    Wrong contour,There is no evidence they are overrun barrels either.

    Call GAP. They might just have a Rock barrel floating around.

    Wrong contour,There is no evidence they are overrun barrels either. </div></div>This is a messed up topic for sure... I went to the Shot Show in Orlando this year and specifically sought out the Remington people to have this question answered once-and-for-all. First I went to the LE/Tactical booth where the guys there told me that "yes" in fact, the barrels on the 5R are over-run barrels from M24's. Then I went to the "Main" Remington booth and the guys there told me they didn't know what I was talking about. Kind of in a "leave us alone" manner. I left the show scratching my head. I've since found out- and I believe this to be the case- that 5R barrels are made by Remington to the same basic rifling specifications as the M24 but M24 barrels are Mike Rock barrels... At least the M24's fielded by the Army. Still not sure about it so take that for what it's worth...

    Rock 5R runs 390.00 for the blank. My buddy was talking to them last month and got a history lesson along the way.

    At one point Rem outsourced their barrels now they are tooled up to make 5R in house. Rem custom shop may be able to rebarrel but IMO a Rock installed by APA or GAP would be much better.

    You asked for opinions so here it goes...if its shooting well dont mess with it! You can get a generic thread protector from AAC thats knurled for about 30 bucks if I remember correctly. Or you can have a thread protector custom turned and blended in so its not even noticable. Either way you would still save some money. As for only wanting 100% correct, I dont see how a carbon wrapped barrel fits that description. Assume you mean Army spec but others buy tha M24 as well and some are ordered threadded so 100% spec is a matter of opinion. Food for thought FWIW.

    Rock blank would run a tad under $300.

    Only very early M24 tubes were Rock products.

    Barrel on a 5R Mil-Spec 700 has nothing in common with the M24 tube other than being stainless and rifled the same.

    Re: Re-barrel a real M24. Options?

    Here's what GAP sent me....

    "We can rebarrel your M24, our current lead time is about six months right now. The work would run about $315 for the barrel, $350 for chamber, headspace and blueprint the action, and $235 for black Cerakote finish on the metal."

    The only reason why I want to re-barrel the M24 is that the can that was used needed the barrel to be taken down a couple thousandths from the muzzle to about 8” back to accommodate his set up. The barrel has three different contours… The factory outside diameter, the part were it was lathed down a couple thousandths and where it was threaded.

    It shoots great … I’ll just put a thread protector on it and wait till the lead times go down….six months is too long for me.

    Thanks for answers,

    Sounds like it's threaded for a surefire break used in conjunction with a surefire suppressor. If that's the case just buy a new surefire break. It wont be 100% correct, but you will be up and running.

    I thought that the original M-24's were built with Rock barrels and after the initial run and after Rock just couldn't keep up with the demand...Remington got geared up to produce the Army's 5R barrels, and I thought they still did.

    The Commercial 5R Remington Rifles barrels are definitely a different contour.

    Would be impossible for these to be over-run barrels as the M24 starts at 1.20" diameter, and the 5R/Varmint contour starts at 1.250" how do they add back the .05" to the diameter when they decide they aren't good enough for the M24?

    I think they decide prior to final contouring!

    Unlikely as it would take lapping and rifling before deciding it wasn't going to make the cut, and this would happen after contouring typically speaking. I think the process is bore, contour, rifle, lap, with air-gauging inbetween steps. I could very well be wrong, but maybe Rock will speak up?

    Re: Re-barrel a real M24. Options?

    well maybe another barrel maker LOL. Someone could comment on the process and at which point they would know a blank won't make the cut as an M24, but will be more than acceptable for 1/2 MOA accuracy on an untrued 700 receiver. Known as some of the best shooting rifles coming from Remington's production side (not custom shop), I am very skeptical that these barrels are showing some sign that they won't make the cut for the M24. I still believe that it would take final lapping to know if something was completely out of whack, at which point, how are they getting such a great rep as 5Rs?

    Re: Re-barrel a real M24. Options?

    I am still skeptical, as I don't think they are starting with 1.250 tubes. That would be the only way it could make sense, but I think they are typically taking something that is bigger than 1.250" that way they can turn it down concentric to the bore to either 1.250 or 1.200". Does that make sense? It would be silly for them to turn them all down to 1.250 and then turn the acceptable or needed ones another .05" further. IMHO the only thing that the 5R has in common with the M24 contract barrels is the rifling profile. I guess without someone knowledgeable on the subject weighing in we are diverting the thread with pointless argument that neither of us can substantiate.

    Sorry for the hijack

    Perhaps the type of steel is also a commonality!

    Re: Re-barrel a real M24. Options?

    Sorry for the bad gouge the pricing my buddy got a few weeks back for the RCB 5R was for a fluted barrel blank for 390.00

    I had to go back and check becuse I couldnt figure out how the pricing cited above were so far off what we had been quoted...the fluting was the additional difference.

    Re: Re-barrel a real M24. Options?

    Straight from Remington military website:
    <span style="color: #000099"><span style="font-weight: bold">The M24 features a Rem®-Tough powder coated 24” Remington stainless steel hammer forged barrel with unique 5-R rifling to ensure repeated high performance over the life of the barrel (The US Army has seen as many as 14,000 rounds fired before significant barrel degradation). </span></span>So it would apear that Remington uses the same stainless in the barrels, the same rifling profile AND process, and manufacturer (themselves). Now, I just don't see a company having a whole separate barrel line for two barrels with the same characteristics.

    My original statement that they're leftover/overrun is probably inaccurate. I see Remington's marketing seeing the "Tactical" market booming, and seeing the 5R barrel production capacity being more than enough to support M24 demand, and the dollar signs start flashing. They even use the same 5R rifling on some of the triangular barrels (700 Target Tactical).

    Re: Re-barrel a real M24. Options?

    Years ago When I sent our M24's back to get rebarreled I had several conversations and emails with the guys there in the M24 shop. At the time I had a Remington 5-R milspec rifle myself. I was curious so I asked them some of these very same questions that are being brought up on here. In regards to the questions that I asked them about the M24 barrels being the same as the 5-R milspec's, I'll quote from the email I received.

    <span style="text-decoration: underline">Quote from Remington M24 representative: " Unfortunately it's a 5-R bbl in name only. It missed some of the operations that we typically perform on a M-24 barrel."</span>

    I asked about it because I had one of those rare 5-R's milspecs that didn't shoot and had a REALLY rough bore. I explained to him that I had talked with a remington factory Representative through email before I bought it and was told that the barrels WERE the same. As you can see from above he said that "its a 5-R barrel in <span style="text-decoration: underline">name</span> only". This came from a guy who is not a Remington salesman but a guy who works in the M24 shop.

    On a side note; after explaining to him the problem I was having with my 5-R, he told me to send the rifle back to him at the M24 shop and he would have his guys lap it and "evaluate it" at no charge to me........ The rifle came back a shooter and he even included a test target with several 5 shot groups using M118lr. None of the groups were over .6" CTC.

    Contour and finish are the two things I can think of. Finish is a fairly easy fix, but the countour thing is hard (impossible in fact) to get over. My statement was in response to a recommendation that the OP get a 5R Mil-Spec tube for his "spec" M24. Glad you got a chuckle while not trying to be an ass.

    Re: Re-barrel a real M24. Options?

    I have posted this on other forums but since it seems to come up frequently, here is what I found for you guys. In making inquiries about M24SWS I asked the supervisor of the M24 shop to return my call. We visited about M24's then I asked him if he could comment about 5R's (the rifle not the process) since they were "classified" and M24's were not. He laughed and answered my questions. The 5R barrels are not/never were M24 anything (rejects, culls). Remington lawyers would never allow anything once rejected to be sold. The barrels/rifles are assembled in completely separate shops because of mil contract requirements. No consumer anything ever enters the M24 shop. It is the only weapon assembled in that facility. Federal prison awaits violators.

    The 5R's are made in their own dedicated shop out of exactly the same steel on exactly the same tooling (albeit the machines are newer.) There are differences in the contour and the process of assembly and testing between the two: proof firing, disassembly, and then magnafluxing of M24 barrels, test firing without the expensive post stress magnafluxing for the 5R. There are other steps performed on M24's to satisfy the mil contract, but nothing that significantly impacts performance as regards the barrel itself. We didn't talk about the action. Remington likes the 5R tooling process for their barrels, so they have expanded it beyond .308.

    I have shot both. I own a 5R now that shoots, as best I can remember, as well as the M24. That is all that really counts for me. Mike Rock made the original barrels before Remington finalized the mil contract so I would look to Mike if you're going to re-barrel.

    Carry on.

    Re: Re-barrel a real M24. Options?

    shadow4, It sure sounds like it. I really dug at him about Remington's "classified" 700SS 5R Mil-Spec and the total blackout of any information - not even a sales brochure. He just laughed. I guess they like all the speculation.
