Army M24 Build Thread

[Ngpodent]

@whitetailnut follow up question; are the Rpa rear sight bases parked as well? I found one old photo previous in this thread where it looks like the front base is matte/park and the rear is blued. Most of the photos I’ve seen look to have blued bases as well. But then there is the photo where the rear base looks parked(or maybe a bead blasted blue?)

 

[shlouf]

getting closer...

barreled action should be done in a month or so, and the suppressor should be approved in a couple of months

decided to go with the xm2010 glass to get some extra magnification and at least remain quasi "correct"

Question on MIRS rails. I know the general difference between the rev a and b is the milling on the wing to see the serial number , but can anyone fill me in on what this circular modification is on rev b rails? I have seen this on both late production rev bs, as well as rev a’s that we’re modified to rev b(as indicated by the milled area where the rail was then marked rev b)

Thanks!

Hey could you give me some screw lengths on those mounting screws? I picked up a rail but don’t have screws

 

[Ngpodent]

Give me a few days, once my calipers are here I’ll measure them up for you

 

[USNavy06]

I really appreciate that. Been trying to figure out which screws I need

 

[riflegreen297]

I found this with a MIRS rail while digging thru some parts boxes. I didn't see it anywhere in the thread and thought someone might find it interesting.

I think that’s what I needed! Thanks!

My humble start.

 

[ODCMP]

Great start!

 

[Ngpodent]

I think that’s what I needed! Thanks!

Yup, looks like those are correct, here’s what I measure on the actual screws

 

[Mach1pilot]

Interesting set on Ebay... Bit pricy for me. M24 kit

 

[mjh30]

Scope would be incorrect, also only has a duplex reticle, case looks good, as is the d kit

 

[shlouf]

what do a set of iron sights (no bases) go for? assuming they are true M24 take-offs?

 

[mjh30]

Redfield or rpa

 

[shlouf]

no idea. is one worth more than the other?

 

[mjh30]

Getting the bases seems the problem for both rpa and the Redfield systems. Bases are becoming scarcer and scarcer. Sarco sold issued rpa rear sights for about 200 a while ago, ok webber is basically out of business out, Otto died a few years ago.

 

[kb1]

Check Outback Gun Parts. I have had luck getting bases from them.

 

[mjh30]

For the Redfield rear base?

 

[kb1]

For the Redfield rear base?

Yes. They make a repro one as well, or at least they did at one time.

 

[mjh30]

Yes. They make a repro one as well, or at least they did at one time.

I think I had the repro, if they sent me the correct one at the time, it's not the right dimensions as the original

 

[mjh30]

Was able to find that repro they made, compared to the original Redfield, a fair difference.

 

[mjh30]

Also I was wondering if others had any reports that the latest batch of BO M24 marked mounts were narrower than the originals and weren't working for em.

 

[benfur]

Which is the repo?

 

[mjh30]

Which is the repo?

The one which has the 60 degree milled edge, (smaller one) the other is just a regular wb-490 which was milled by Remington to fit.

 

[kb1]

Yeah, that isn't even close.

 

[sinister]

Warner Machine Tools still makes a base:

The Redfields clear the aft ring clamp nut, while the RPAs were cut and relieved:

 

[Ngpodent]

Also I was wondering if others had any reports that the latest batch of BO M24 marked mounts were narrower than the originals and weren't working for em.

I have a recent production badger mount. Current production leupold mark 4 rings, and sei rings fit without issue

 

[Ngpodent]

I know the McCann Mirs for the M24 was a 0 moa mount, but can anyone confirm if the correct uses MARS mount was also the zero moa variant? I assume 0 moa would be correct when using the leupold mark 4 scopes

 

[mjh30]

I am under the impression that is correct, that is correct that zero moa rails were used.

 

[eodsix]

It was my personal experience with a G M24, Zero MOA MARS and a Mark 4 M3 3.5-10x variable illum that I needed the 20 MOA because I couldn't engage targets beyond 800 meters, the scope elevation knob topped out. I had to get a 20 MOA MARS to compensate. I did not test the M3a Ultra scope on the MARS so I can't speak to that. Clone correct or not for me wasn't the question, what worked was.

 

[Master Gunny]

M24 with 0 MOA MARS. I am rolling a Sig Tango 6 5-30x 34mm scope so I don’t run out of elevation 800+. It shot 10 shot group from prone at 300 yards. .80 MOA. 5 MPH wind. I will take that all day. Gun has shot 3 shot groups at .18-.6. Averages .5 or better. 175 FGMM seconds (visual defect)

I also roll an FN SPR A4/A2. Solid rifle but just slightly less accurate then the M24. Just barely though

 

[Master Gunny]

I want to start bringing over some of the technical stuff that was on the old thread:

I am looking for Badger PN 306-85. M24A2 bottom metal. I already have 306-84 (rare). Can anyone help me? Thanks

 

[physhphude]

Also I was wondering if others had any reports that the latest batch of BO M24 marked mounts were narrower than the originals and weren't working for em.

That is correct. The current production badger M24 mounts are too narrow for the original leupold ultra mounts. Normal picatinny type scope rings will fit though.
If anyone has an older wider mount let me know. I will trade/buy it from you.

 

[Ngpodent]

Not sure if it’s okay to post links, so if it’s not let me know and I’ll edit my post, but I found a source for Redfield reproduction parts. The rear base will have to be modified for ring clearance, and the front base(under scope blocks) will have a dimple on the side opposite of the crescent cut. Doesn’t always appear to have inventory but considering how hard originals are to come by, thought I would share.

redfield

Also, if anyone is looking for a MARS, century arms has some 0 moa, and 30 moa long action mars in their surplus corner, but they are pricey.

For myself, if anyone has a source for the old Leupold mark 59230 mounts(the ones that have a shallow countersink in the rear that uses a longer screw compared to the front) I would appreciate the lead. It’s the last piece I need to finish my build(using current production in their interim)

 

[Master Gunny]

Shot the girl (Lola) today. 10 shots 300 yds 2.6 inches. Prone. 175gn FGMM

 

[Ngpodent]

Anyone know if the mars recoil pin is supposed to be angled forward(toward the receiver) or straight at a 90 degree angle? Just need to confirm if I need to reach out to century to swap mine

 

[Master Gunny]

What is the worth on a new take M24 stock?

How about bottom metal?

Badger ordnance M24 bottom metal?

Thanks

 

[shlouf]

Demand for m24 parts is only going up with all the actions sold on gb over the last few months.

with a mag, I wouldn’t sell that badger bottom metal for anything less than 500

Is it 306-85 or 84?

 

[shlouf]

I’m glad I found my m24 can when I did. On arf, Ron A made it sound like there won’t be any more of those made before he retires

9 hole reviews took out a m24 to the range.

I watched it yesterday, being honest I like the first two minutes of these speedway vids and then I move on to something else when they get to the commentary.

Their videos seem a bit more show offish then scientific in my opinion.

 

[Master Gunny]

I really enjoyed the vids. I am more experienced with M40A1/A3. I have fallen in love with the M24. I really like the detailed vids. Thanks for sharing them.

 

[Master Gunny]

I have never understood why anyone would spend HUGE $$$ to replicate faithful the M24 when you could build a rifle as good as or better for less than 1/2 the money!

I grew up with the M24. I learned to shoot at Ft. Benning and my dad was career Army for 23 years! Shot it plenty of times and remember his soldiers at Ft. Stewart begging like a little kid asking for candy to take the M24 to the range for live fire! My best friends dad was an instructor at the Ft. Benning Sniper School and was a sniper his first and second tour of Vietnam.

It was a good system considering it was knee capped with the 7.62 NATO when it had been designed and was actual desired in 300 Win Mag.

In fact my first rifle that I purchased for myself in around 1995 in college was in 300 Win Mag. based on my experience and instructors/mentors at Ft. Benning. I had no desire to do the 30-338 Win Mag.

In fact even if you gave me the original optic for free I would rather run something else.

When you look at everything on the market for the Remington 700 action especialy given the barrel choices and optics available today and triggers I do not get the desire for 100% accuracy.

I am not faulting anyone that does want to do that I just can not wrap my head around it. I would especialy never use a long action if I was going to handicap myself with 7,62 NATO. I love standard and magnum length actions but not if I am going to run a short cartridge that just makes living with the rifle difficult at times when trying to run a fast time on a timed course.

I wonder how cheaply I could build an M24 killer? LOL


To bad no one makes an affordable transit case like the original!!!! Out of everything I would like to have the case more than anything else!

My F-T/R cost a lot less to build than a faithful M24 and is far more accurate I do not get it? I do not shoot M118LR but shoot hand loaded Berger 185 Juggernauts.

Why? Help me understand the point of spending $$$$$$ for what is a compromised system from top to bottom?

You completed miss the point. If you don’t understand then you never will. The M24 is a 1/4-1/2 MOA rifle in 308 (7.62). People love old school sniper rifles. I used an M40A1/A3 and love that people duplicate and collect them. I am not block headed enough to as you say (wrap my head around) to understand. There are better calibers and systems out there. If you don’t understand the attraction then you should probably not post on this thread. The thread is about love.. building, cloning, duplicating the M24. You obviously don’t love the system or you wouldn’t have posted what you did. That’s ok though. Enjoy your 300 whatever….

M24s are cheap as far as clones go. Go venture into the gas gun clone threads and let us know how you feel about guys spending $10k+ on a m110

Fclassparadise is a knucklehead. I just read all 12 of his posts. All are the same BS type of posts. Brings nothing and talks to much…. Don’t feed the troller

 

[Ngpodent]

I understand the contract spec for these rifles is the 10x scope, but have seen the variable power scopes mounted ina few rifles, per this thread the pre-mk4 vari-xs were used as well https://www.snipershide.com/shootin...pes-ever-used-on-m24-military-rifles.7032813/

I assume the vari-x scopes were second focal plane, but does anyone know if the mk4 s used were first focal plane? I assume the socom contracted night vision systems used the mk11 ffp scope with McCann rails, but would all of the other 3.5-10s be second focal plane?

Buyer beware on this Gunbroker auction:

GunBroker.com - Error

The description looked familiar to me, especially the first sentence about the rifle being "leased by Remington to the U.S. Army for training in 2006." A quick search found the Rock Island Auction where I had seen the title and description before.

Collectible Firearms for Serious Gun Collectors

Rock Island Auction holds over 12 gun auctions per year. We buy & sell collectible firearms for serious gun collectors, including antique firearms & military arms. Click now to start selling your guns & investing in collectables today.

www.rockislandauction.com

This is a different rifle and different serial number, but much of the description is the same. It may just be an unknowledgeable seller trying to copy an old description and not knowing what to delete. But I seriously doubt that this rifle was also "leased by Remington to the U.S. Army for training in 2006."

I sent the seller a message yesterday asking about the lease documentation, but haven't heard back.

Just a heads up.
