Actually, probably the best video I've seen on C308 disassembly. Picked mine up last month at Cabela's. Ordered 20 extra magazines from Cheaper Than Dirt, since they had free shipping on orders over $50. Don't think I'll ever need to order more.

For those whom have never worked with feeler gauges: 1. The resistance should be similar to pulling a sheet of paper out from under a magazine. 2. Close them by grouping thinner gauges to thicker gauges. This prevents bending or kinking that can ruin a gauge. 3. Wipe gauges with a lightly oiled rag to prevent corrosion. 4. Always store closed in a safe location, separate from your other tools. Keep measurement and indicating tools in their own drawer, bin, or similar to prevent damage. They are some of your most important investments to producing quality work, with when checking firearms or fabricating parts.

Thank you so much for making this video! I have taken the delayed rollback part apart before and had an absolute nightmare with trying to figure out how it gets put back together without instruction. For somebody that did this for their first time, you did a really good job of showing how it's supposed to be done.

Just got my C308. Reassembled the bolt to the locking piece and carrier, but could not get it to unlock to loosen the rollers so it could be reinserted into the receiver. Glad I found this video, by moving the bolt back a click and using a file as leverage, it`s in and functional. Off to the range right now.

Thank you for this video! Excellent step by step instructions. I've never had a roller lock before, now I'm not as afraid to disassemble the bolt for cleaning and maintenance.

OMG, this video saved my ass…my rollers where stuck in the rear position and I couldn’t get the bolt carrier group to slide back in….thank you.

Quick tip. To get the rollers compressed after reassembling the bolt group, turn the bolt carrier backwards and push it down into the receiver. The frame will force the rollers in and open the bolt. Then simply pull the bolt out and flip it over and install as normal. Hope this helps some fingers from damage.

Good luck keeping that thing clean lol. They get very dirty, by design though. That’s about how they look after 80 rounds. Amazing to me how reliable they actually are, a reputation for being reliable too, but being as dirty as they are. I still like my PTR91. Mine setup with the wide grip hand guard and the metal HK bi pod.

High 5's on your clarity of explanation and the ability to actually see (great lighting and focus) what you were doing. I purchased my Son's C308e and, after numerous months, I'm pretty sure he's not going to be buying it back. Looked at it this morning and I don't think he EVER cleaned it. Now I can comfortably break it down and get it ready for it's maiden voyage at my local range. Thanks again. ~G.Alan Fink NRA RSO and Firearms Instructor.

I do have some experience with the HK G3 series of rifles. I hate the lack of the magazine paddle, and I do prefer the HK style rear drum sights. Other than that, these rifles are machines that are meant to be used.

Thanks for a great usefull well made vid. I just today got a CETME (Spanish) rifle, made as semi auto for civil use (!) and as new old stock, had been converted from .307win (a rimmed .308 as the latter was forbidden to civilians in Spain) to .308 using new HK G3 bolt and carrier. So I end up pushing the bolt into the bolt carrier and it clicks and out pop the rollers, so I couldn't get Humpty together again! Thanks a million for this video, you saved me mate. The bolt parts are all black and pretty tight, springs are very strong, to turn the bolt on the carrier I used a wrench on the side flats as I was afraid to damage running surfaces. BTW the external metalwork is gray phosphate and the furniture is wood with the old STG45/K98 slot for the carry strap through the stock. these old guns have magazine paddle and even feature the full auto markings on the lower receiver with a stop to emphasize it wont work.

When using the feeler gauge, start larger and work down. If you start with the smaller and work up, you can get a false reading because you may be slightly wedging the bolt away.

Free tip: The pins should go in in alternating directions. Soldiers did this to prevent them being accidentally being knocked out. If they go different ways you can't accidentally knock them both out.

Rainy Sunday, cozy garage, working on guns... ASMR 😁

Gotta love being multilingual. The Spanish videos of actual soldiers who used these give great tricks for maintaining these rifles and you don't have to understand Spanish to see them. But apparently one trick is to use the sling to remove and replace the bolt.

Just ordered one, can't wait to get it. Thanks for a great how to video! Will do this as soon as I get it home.

Great job. Love my C308. Great shooter.

Great video, just did my 1st breakdown and cleaning watching your video. A great aid as I really had no idea what to expect. You covered it all perfectly, many thanks!

I had never done it before last night and it took me about an hour to get it back together. Wished i had found your channel last night. Did a really good job of showing how to do it right. Now i will have to go take mine back apart and check everything. Thanks. Have you done a video on the trigger pack?

Solved my problem! Used metric mags instead of inch. Got locked up. Thanks so much!

Good video Nolan. BTW the part that comes out after the bolt is called the Locking Piece.

Thank you, it helped a lot on my first try. My bolt latch spring is way harder than it needs to be. Im plenty strong, but that spring is ridiculous.

Thank you for the video, I've been trying to decide if I want one of these or not. I'm just enough of a gun wonk to love this kind of disassembly.

I was out with my c308 at Kingsbury in the cold. Very entertaining rifles.

Thanks for the video. Its been a while since i stripped my century arms clone. Forgot how to do it

The battlefield way of checking the bolt gap is disassemble it right. Push the bolt back against the carrier and if the firing spring is not pushing out then your gap is wide enough…. If your firing pin is sticking out a little bit when at home that’s dangerous grounds for misfire when chambering and also a runaway rifle which is terrifying. But if the firing pin is only sticking out when you press it in from the rear of the carrier and not any other way then you’re safe. My Daniel defense DDM5V1 terrified me… it would always put a little dent in the primers when I chambered one because of the free floating firing pin….. I was going to install a firing pin spring or even make one to make it a little safer… thank God for the ultra hard primers otherwise I’d be injured by now. But yeah that’s the reasoning behind it from my knowledge and if you don’t see the firing pin then you’re good to go. The spring is like 100000X safer than a free floating pin.

I could figure out how to release the rollers. Thank you for the great video.

Awesome as always Nolan!

Great job on the video. Thanks for the Intel, now I feel bett about stripping mine apart for its first good cleaning.

You ABSOLUTELY MUST completely strip these guns and clean them like you would any other Milsurp. Mine still had quite a bit of cosmo in and around the bolt, Receiver and recoil assembly. I used PB Blaster and Break Cleaner and scalding hot water for the initial cosmoline clean, then I go through with a standard cleaning and finish up with a bit of oil.

Very nice explanation on the basics.

Please keep in mind it's a military rifle. You have to do the assembly and disassembly without tools, blindfold and in as little time as possibly.

Actual Bolt Gap Check 16.19 great vid thanks much

Nice seeing a Cetme with a Cetme magazine

Easy way to release the rollers from the locked position is to insert your carrier into the receiver backwards and shove it in. The edge of the receiver hits the rollers and releases them.

You could get a job at Copper Custom! haha Great video.

Thanks a lot I hav one more payment before i get mine!! Will pick up a gap gage also will clean before using Thanks.!!

saved my butt..thanks

Pretty informative video, although there is a procedure for pushing in the extractor to make it easier to rotate the bolt in the carrier... Otherwise... Decent video... Thanks

Locking piece should be at an angle so the sleeve is most prevelant through the 'window' When putting the bolt head back into the carrier(upside down): push all the way in, turn clockwise one click, pull out, turn clockwise second click, pull out, turn to third and final click. Done. Bolt will be in its correct orientation

nice vid have yet to found many vids or recent forum post about these or this process.

Nice vid.

Great job brother.

Is the charging handle supposed to move with the the bolt carrier when you fire? Mine did it from day one.

Very informativ, thx

Ensure that the rear of the bolt was NOT filed at the factory to create a passing headspace. If you're sure that it has not, then order + o r _ .02 or .04 mm rollers from Robert RTG parts to bring your gun into spec. or improve its existing spec.-John in Texas

Great video. I put a front sight adjustment tool up for sale on eBay. Hard to find.

My charging handle is loose, any suggestions? Just the handle, nothing else.

Mine measured at 0.10mm is that good?

Any reccomendations on an action that seems to stick. Sometimes its easy to pull back. Sometimes i feel like thor would have a hard time with it

hello everyone. I have recently acquired a CETME C and would like to know the production date by the serial number. where can i find this out. and I noticed that my rifle does not have these bulges for mounting optics. do you know why?

Hey I was wondering if you had a video of replacing the recoil guide rod?

I can’t figure out how to get those rollers back in and not sticking out of the bolt so you can put it back in the rifle

I got my bolt stuck after the second turn and now I can't get it to go either way. What did I do wrong and how do I get this thing apart now?

I have a Century Cetme. I have an issue with the charging handle not able to disengage the bolt to charge the rifle. Does this have something to do with the bolt gap or rollers? What do you recommend? Great video btw.

You're firearms don't work in the rain? :)

Will yours accept the original wood furniture? I had to sell mine but found one like yours but want to put the wood furniture on it, polymer hand guard rattles, about 1/8 inch slop. Guy put an AR style buttstock on it too, idk why. But $650 is a steal !!!

You forgot to disassemble the extractor from the bolt. Not the grimiest part but the most delicate. Pull the extractor spring forward and it falls apart. You should have gotten a tool for it with the rifle.

My C 308 bolt carrier is real tight when pulling back ,you think needs cleaning ?? and little oil

No utilizar una lima para montar el mecanismo de rodillos, con la correa del Arma roscado alrededor como una polea lo cierras, de esta manera no dañas el complicado y super efectivo y eterno sistema de cerrojo, un saludo.

Can you check bolt gap without the barrel pressed?

You think you cleaned up your G3A3... I think you're up to get a weekend pass revoked... Hellenic Armed Forces.

When reassembling the bolt carrier, after the first click and when I get to the second click it pops loose. Anyone know why?

So what do u do if the gap is too tight or too large?

thanks for sharing, what is the cocking tube gap like on your rifle? Is it hard to pull back? Thanks

thanks so much for giving me the confidence to take mine apart..... just shot it today and it needs a good cleaning...… have you tried shooting steel case ammo in yours ??? mine is killed the brass. thanks again for a GREAT video...

How's the rifle holding up for you?

Buy .04mm+ rollers from RobertRTG-Easy way to improve headspace on these sheetmetal monsters!;)-John in Texas

Stupid question: can the rifle fires if you remove the bolt?

I took out the pins but the butt stock just won't come off

What’s the tool you using

Put back right way at 11:30

Is that a full auto bolt carrier 😂

My charging handle won't go all the way back after reassembly

I absolutely cannot get my bolt past the second click on reassembly, no matter what I do

its a MP5 pistil grip not a G3

please dont ever grind your bolt face. this can be catostrophic.instead you must reheadspace the barrel when changing roller sizes

♿♿ ♿♿

Looked at a CETME 308 at a well-known outfitters location and it was a piece of 💩 Would not recommend spending hard earned money on this particular rifle.

OMG Kid. You really have to waste so much time talking in circles?

Omg please talk less man I never comment this is literally my first time but you blabber way to much man. Thank you but come on
