Out of state dealers have not been willing to take the mussel break and pistol grip off and send a ten round or no mag to my ffl dealer. Even the ras 47s are the rare here but there are a few available. I'm in between a rock and a hard place Dealers are selling those here for 800+. we're screwed.

      +metaltrooper62 I was already doing the headspace filming when I remembered an AK Files member said it would be nice to see some spent rounds. So I put the hand guards and internals back and replaced the rear sight slide. But when I got to the range I decided that placing my face on an iffy rifle I was not trying to check for accuracy might not a good idea.The gap thing.....no two rifle will be 100% identical. So I made sure to mention that. Like I said, people would ask me all the time when they measure the gap, how much should there be?

    The head space on my chrome lined 5.56 74 is very similar to the snap in lock up with the go gauge you're showing with the maadi, but the gap is a little less significant. I'm pretty sure I have a rough chamber issue, still even after lightly polishing the chamber with 0000 steel wool and running the bore brush from the cleaning kit in there with a dab of brasso on my cordless drill. I'm glad I watched this video I was concerned with the gap I was thinking it was supposed to go all the way over with the go, phew. lol... well the first outing before I lightly polished the chamber it was stuck cases every shot fired, the carrier/bolt is grabbing new rounds out of the mag so I know it isn't under gassed, lost a few hot rounds do to them slamming into the stuck cases, then I smartened up and started loading one at a time. After lightly polishing the chamber I'm still getting stuck cases every 3 rounds or so but it has improved and that is all I have changed and rechecked headspace after polishing, no noticeable change. I still need to try some steel cases and see how those extract as well. I have somewhere around 80 rounds down the pipe on this thing as of today and its getting old loading one round in the mag at a time lol. Think I'm gonna polish the chamber a little more, I have a different extractor to try as well now, I need to pick up some steel cased rounds and maybe try a extra power recoil spring and see how it goes as I experiment.

    • @Mel64d
      @Mel64d  8 років тому

      What ever you try, do one thing at a time. This way you know what the problem is. If you swap out or do 4 different things all at once and the rifle starts working correctly.....which "fix" was the fix.???

    • @brianpresto1446
      @brianpresto1446 8 років тому

      +Mel64d Yeah that's some good advice. I have swapped the extractor to see if that helps, I may polish the chamber a little better and test it out. Polishing the chamber just a tiny bit seemed to help so I'll step that up a notch and recheck head space as I'm polishing to ensure I'm not messing anything up. I just stripped the rifle completely today, degreased scrubbed and wiped it all down and hit the whole barreled receiver, dust cover, etc, with Rustoleum Appliance Epoxy. Seems like a pretty decent far cheaper alternative to Duracoating and the finish looks almost identical to the safety lever that I didn't refinish. Around 6 light to mediocre dustings and it has that nice kind of slightly textured satin look to it. I don't have anymore of the PPU 223 so I can't verify if it runs better with the changes I'm gonna make when I test. I did run some Independence 5.56 through it and it seemed a little better but not much.

    • @brianpresto1446

  • @michaelbenjmitchell1
    @michaelbenjmitchell1 8 років тому

    came up better this time. Good thing you didn't blow yourself up with those 12 extra rounds Mel. But I think the RAS47 can be brought back to life with a properly headspaced barrel new FSB and new rear sight. The furniture is junk anyways and can be replaced. There seems to be something funky with the BC if the piston was getting damaged but I think the lightning BC is probably too fast for its own good. and the loose rivets can be re crushed back to proper tightness.

    The information you explained here blew the cap off my novice ak47 brain. I own a RAS47 and was very happy with it's performance since purchased in Nov. of last year. Now up until last week, aprox 1k rounds down the pipe I am consistently getting feeding and ejection failures with different brands of ammo/mags. My bolt, carrier and trunnion(s) has the same wear as in your video and AK OP's 5k round video as well.
    I truly wanted to believe the bad rep Century Arms got was just a whole lot of bias opinions and reviews or lemons. My question is: if the headspace is off and causing the failures, how can it be repaired and is it worth to fix?
    Thank you

    • @Mel64d
      @Mel64d  7 років тому

      If you can do all the work yourself then it's better price wise anyway. If you take it to a company to do the work then you are looking at a little more than half if not more than the price of a new WASR10.
      The barrel will need to be pulled and a new trunnion and bolt (should replace carrier too) need to be bought. The old trunnion will need the rivets removed, then the trunnion can be removed . The holes in the receiver for the old trunnion will need to be filled (weld) in, not all three on both sides but the two upper rivet holes on both sides will need to be filled in, ground smooth, then locate and drill the correct hole placement for those four upper holes. Then rivet the new trunnion into the receiver and press the barrel back in and re head space and drill for a new barrel pin. Then if you want the finish to all be matching....
      See, nothing to it.
      This is why I said if you can do all the work yourself it's way cheaper.....but this rifle (ras47) really is not worth the time, money, or effort to make it correct.

      Seeing as it's a 10/63, I'm guessing its had at least a couple of previous owners that may have (for some reason) replaced the bolt or barrel at some point and the head space is way to tight now as a result.

    So, If the RAS47 when new is headspaced to fit tight on a GO gauge then not lockup on a NO GO gauge it should be fine and at the end of 5K rounds it would be still be within specs.

    • @Mel64d
      @Mel64d  8 років тому +1

      +Timothy Powell Not necessarily, The metal used for the bolt and trunnion are not up to spec. Well the trunnion is closer than the bolt. But the material seems as if it might not be the right stuff for the job required. Seeing as the bolt deforms as easily as it does, then even at the 5000 rounds count there very well could be enough deformity to cause the headspace to become very loose.

    • @Mel64d
      @Mel64d  8 років тому +1

      When a firearm starts loosing headspace, the potential for the weapon to blow itself apart becomes more and more. Usually it just scares the hell out of you and makes for a cool story later on....but sometimes.....you can get seriously hurt i.e. fingers blown off or an eye put out, maybe both. There are tremendous pressures involved when a round is fired. The bolt and lugs must contain those pressures when the weapon fires. If the headspace grows to much, then the bolt and lugs will eventually loose their containment (grip) and the weapon will violently on lock and or blow apart. It's definitely not something one should overlook. Especially if you like to let your loved ones shoot.

      Most barrels if the journals are machine correctly will go in far enough that the breech journal will have a tad sticking out the front of the trunnion (breech block). You can press in and periodically check with the bolt while setup in the press (if you've given yourself room that is). Sometimes it's a lot of going in and out of the press to check fitment. Kind of a pain, but it is what it is.

    so a no-go should not turn the bolt at all while the GO can got with a gap or not?

    • @Mel64d
      @Mel64d  7 років тому

      On an AK there is no minimum amount of force for the Go Gauge. Zero (0) to 33lbs. for the Go. So if the bolt rotates on the Go with little to no effort, then the No-Go will start to rotate the bolt. This is not considered bad (for the AK at least)...just way loose. For a new built gun (while building) a Go and No-Go are used to set head space. The Field Gauge is only for checking out in the field (hence the name) to see if a WELL USED rifle is getting to the maximum allowable amount of head space before catastrophic failure could happen.
      The "Gap" is from the bolt rotating 38 degrees for lock up. This will leave a gap in-between the bolts cam lug and the right side of the receiver. The gap should not be the judging factor for setting head space.
      In Russia they consider the rifle to only be in need of repair if it fails the Field Gauge check.
      In America we consider the rifle to be in need of repair if the No-Go fails.
      The AK is a weapon that is made in a way that loose tolerances, and loose head space, can still make for a usable weapon.
      That is blasphemy for any weapon made in America though.

      @Mel64d  6 років тому +1

      With the bolt stripped and even the hammer (safety reasons) removed. Will it close on a live round? If so then you are probably good to go. If it's to tight it can be ammo specific. So you may have to shoot that brand of ammo for a bit until everything loosens up. My builds all have the 'Go' tight.
      The bad thing about "All American Made" AK's is, they can machine the parts but have no clue how to fit the parts together. The AK is not like the AR. With the AR's you can CNC machine the parts and then assemble the rifle and basically you are good to go. Not so with an AK, no matter how good the machining is with the AK parts. You still have to hand fit the bolts to the front breech block, i.e. trunnion. This is why the "All American Made AK" fails...it's to damn expensive to have a warehouse full of people just hand fitting AK's together.

      Mel64D thank you sir ive just been worried about my front trunnions right side locking shoulder, it seems to have deformed/folded quite a bit and even the bolt locking lug that rides and locks to the right side of the trunnion shows a little mushrooming. The rest of the bolt is fine with no wear also the left side of the front trunnion (the primary locking side)looks perfectly fine.

      Tsquare28 Century made poor copies of ak’s to sell to consumers who know nothing about them. If you were to purchase a rifle either imported or built by a reputable builder from a com bloc parts kit. Then you would have yourself a good rifle. Century has given the ak a bad name in the attempt to sell an all American made ak. They failed. Well the succeeded at making a profit from them but failed at making anything even remotely close to a real ak rifle. Now consumers like you think all ak’s are piss poor like the Ras47 and c39’s because of Century’s con job they pulled.

      Mel64D I give a flip. Just put a Romanian mk99 on layaway full utg furniture set and had a dark black coating on everything. Don’t know a whole bunch about ak47s just thought it’s time to get one with what’s happening in Virginia. Well started watching all these videos about what to look for and honestly it seems their is more to go wrong in a ak then any other firearm I’ve read or heard about. Are these things just ticking time bombs? If their is anything wrong with it is their anyway I can replace the parts? Like buy a new BCG and drop it in ect? If you have time do you have any opinions on the Romanian mk99? Is that the same thing as a wasr? Because I been searching UA-cam for a few days and noones description says mk99 or Romanian mk99 so I’m just extremely lost over here on what I’m actually getting rifle wise.

    I have an AK that headspaces correctly but the lug does contact the trunnion with no gap as with this RAS47. What do you think?

    • @Mel64d
      @Mel64d  8 років тому +1

      +Lori McGeary The gap is ideal...but not 100% necessary. Some rifles have no gap, some have a little gap, and some have a big gap. Just check with the NoGo and Field. Just because the NoGo will close, does not mean that the rifle is out of spec. If it just falls into battery with no effort on the NoGo, then the Field gauge must be used. When the rifle will close on the Field, then it should be deemed unsafe.....but even the Russians are a little iffy with the rifle closing on the Field.

    how does the headspace increase as the rifle wears? Is the barrel physically being moved forward over time?

    • @Mel64d
      @Mel64d  7 років тому +1

      Different things can happen to cause head space to increase. With the ras47 in this video, the front block (trunnion) is an inferior casting. Same with the bolt. Casting can work if done properly. But the ras47 is built to the cheapest standard possible. The casting specs that Century has set for the ras47 keeps the rifles cheaper....but more dangerous for the consumer. Century is banking on the vast majority of buyers to only put a few hundred rounds a year through the rifle. Even this is a bad idea, because the rifles will eventually reach a high enough round count that the problems will still present themselves. It will just take a bit longer.

      If any rifle closes on a field gauge it should be repaired before shooting again. If you wish to replace said rifle with a WASR instead, that's fine too....but if you sell the out of spec (head space) rifle, then a full disclosure of why you're selling it should be done.

      +fioshd97 For what it's worth, 5000 or more rounds will take the average person YEARS to fire. Even then there are those who have fired close to that or beyond with no headspace issues or excessive wear. Take Mel's advice and simply headspace every 1000 rounds or 35 mags (packed to 28 rounds and not 30 ) . Think about lubing an polishing any, and all edges lightly with sandpaper and then lubing area that contact the lugs. It will be years before it'a and issue if you are like 99% or Americans who shoot less than 1000 rounds a year. Just my 2 cents as a RAS47 owner with no worries or issues.

    • @Mel64d
      @Mel64d  6 років тому +2

      Head space is the measure of safe distance between the bolt and chamber depth. If it's to short then the gun can have malfunctions or only work with "x" brand of ammo. If it's to long then the gun can have a catastrophic malfunction (explode in your hands right next to you face) while shooting. Gauges will help determine if your head space is good or out of spec.
