Thanks. That's why I didn't order it because I was didn't want an 8620 bolt. Like I said I think all my other ones are either 9310 or 158. Google was turning up nothing on either 9310 or 158 bolts. View Quote View All Quotes View All Quotes Quoted:

I'm looking at 7.62x39 bolts and I'm seeing that they are all 8620 Steel. I'm pretty sure my 6.8 bolt and both of my 5.56 bolts are 9310. Should I be concerned by this or not so much? Do yourself a favor and spend the couple of extra bucks on the Cason or the LMT. They will last far longer then anything else out there. Will make the gun run better with fewer complications and are easier to clean up. Neither of those will be made out of 8620 and they are far superior to anything else out there. Thanks.

I believe that the Cason is made of aircraft grade ss with a chrome coating. The LMT is some sort of aremet steel which I won't even begin to tell you I know anything about but they do last in the x39 which is very hard on bolts. My Cason is going strong, no probs as of yet and I use it.

Muzzle brake question:
I bought a YHM Slant Muzzle Brake (see below) in .30 cal with 5/8"-24 threading to match my barrel. http://yhm.net/30-cal-muzzle-brake-308.html I was browsing the YHM website because it didn't come with a crush washer (and it needs one) and I stumbled upon the 9mm/6.8/7.62mm version (See below again). It says "Rated for 9mm, 6.8 SPC, or 7.62x39mm". So, what one should I be using? This whole time I was under the impression the one "rated for .30 cal" would be appropriate for this caliber. http://yhm.net/9-slant-brake.html |

You said your barrel is threaded 5/8x24 so it sounds like you have the right one. The 9mm/6.8/x39 model is threaded 1/2x36. |

Okay then I'm good to go. Just was a little concerned is all before I go shoot it
Thanks |

This is Cason Engineerings web site address if you need it in the future. If you shoot a couple of thousand rounds, you most likely will.

Got my muzzle brake, bolt and charging handle today. Also ordered my barrel from Green Mountain. Going to start assembling the upper this week, well as much as I can without a barrel.
I have a question, the bolt didn't come with an o-ring on the extractor spring. All of my other bolts have one. Should I buy a Crane o-ring or not so much? |

To the OP's question should I build a 7.62 AR? The answer is ABSOLUTELY YES!!!
I'm a new site member but have been lurking/learning a ton for a while now. Do to the responses in this post I went ahead and took the plunge and built my 1st AR as a 7.62 (to be a little different than my friends). I bought the Palmetto State Armory kit that just required a stripped lower. I assembled it about a week ago and fired it on 12/31/15 and then again today on 1/5/16. I went the preassembled route after reading some of the issues others had with trying to build 'from scratch'. I can say that the PSA kit is AWESOME! I used the ASC 30rnd magazines and Wolf 123Gr. FMJ steel cased ammo. My issues to date with 180 rounds thru it are as follows: 1) Very first round didn't chamber when I tried to charge it. (Brand spanking new ASC magazine) 2) 2nd round didn't charge properly and scratched the case. (Both of these rounds did load and fire properly later) 3) I've had 2 light strikes. (They both also fired properly when reloaded) THAT'S IT. Besides the above, this kit and gun have worked flawlessly! Thanks to all who shared their experiences and encouraged all the rest of us wondering about a 7.62 AR to build one. I now encourage everyone thinking about this to build a 7.62 using PSA's kit or upper. You WON'T be disappointed!! |

Does anyone know if you can use a 6.8 mag for 7.62? I can't find any 7.62 mags but have some extra 6.8 mags.

Looking at LCJWholesale's site, I see 28 and 30 round 762x39 mags. Is there a reason for that, like one being less reliable than the other?
|
|
LCJWholesale sell CPD mags for 7.62x39 cal- this is what you need to feed reliably in your AR. The 28 rds mag will fit in the US GI mag pouch , designed for 30rds 5.56 AR mags. The 30 rds CPD doesn't fit but it should be just as reliable as the 28 rds mag.

Just checked gunbot end it appears that the lowest price per round is almost exactly the same for 7.62 x 39 and .223 Steelcase (21/22 cents)
I have been debating this idea, but the "shoot the cheap Ammo" argument seems to not hold true. Now, is it really worth another caliber, new mags, etc? Someone convince me (or not). I have been on the fence for a while. I found a KAK Industries barrel for $110 (made from Green Mtn blanks) and I have all the other parts (unless I need a new BCG and mags) Help me arfcom, you are my only hope for my first world problems |

the main reason I went with an ar chambered in 7.62x39 vs 5.56 or .223 is my military experience
I was a gunners mate attached to a seal team and shot about 150,000 rd to 250,000 rds a year I got used to 5.56 and just didn't like its performance in a short barrel plus I like having a 123 grain bullet or a 154 grain soft point steel cased bullet for 4 cents more a round if u look at 223 its the same price but if u want the higher pressure and faster round and get a 5.56 the price goes from 22 cents a round to 27 to 34 cents a round big jump for little difference also when the gun craze was going I was still getting 7.62x39 for 20 cents a round where as .223 and 5.56 was going for 32-38 cents a round which was to much of a fluctuation for me also it was to main stream to me honestly if ur into 223 or 5.56 its easier and cheaper to stay into it but for new building ar guys its the same price for 7.62x39 for parts and getting into a different caliber for first time guys I have five friends that all started ar-15 life with 7.62x39 and only one has had a lug break on him and he got out of it and got a 5.56 ar but now after about 1000 rounds through his he doesn't like it and wants to get back in 7.62x39 honestly most of the problems have been worked out of the mags and anyone without experience can make an ar in either caliber just personal preference I think now. but comparing 300 blk out and 7.62x39 I have convinced 10-15 people out of the round at the range after they shot my gun and they already had a 300 blk out pretty funny when they are shooting for 50-80 cents a round and im practicing for 20 cents a round with same size bullet and full mags I think most people build them because they can they are legal to hunt with in most states that require a 30 cal bullet and after u figure out any issues in your build they are great so that's my reasons and rant have a great day guys |

Parts are starting to roll in. In fact all the major parts are in. I'm having my buddy weld up my muzzle brake this weekend. All I'm waiting on now is the small parts, spring, detents and take down pins. I ordered them from RRA last week. No idea of they've shipped or not. They are sparse on communication; but I've ordered from them in the past and I've always gotten my stuff so I'll just wait. My PSA trigger came in today.
The only thing I need to decide on are sights. I'm kind of leaning towards a carry handle and a picatinny mounted A2 style sight which kind of makes me want to buy an A2 stock. I already have a full length ACE skeleton stock I'm not using so I'll throw that on for now. |

I like the updated build.
