I put a BCM enhanced trigger in mine. works like it should. so id imagine most of the others work just fine too. and yes there will be a few parts left over when done. |

I've been tempted to purchase the KS47 lower many times, especially at the Black Friday sale price but I'm not going to buy a complete upper from them. I want to build my upper the way I want to build it.
Why hasn't PSA begun selling the upper to match this lower? I'm sure I missed the answer ten pages ago but I feel PSA has lost a ton of orders for not following up with their uppers. |

I have not had a problem with any mag (except tapco mags) since the minor machining of the bolt that I mentioned a few pages back in this thread. This includes using the mag as a rest or uni-pod. I have been confident in my KS47 ever since! |

I simply removed the bolt from the BCG and milled off the bottom corners of the 4 o'clock and 8 o'clock bolt lugs that were making contact with the magazine feed lips. The 4 o'clock lug needed a bit more material removed than the 8 o'clock lug as it was shaving down the left feed lip more than the right on my pmags. My 4 o'clock bolt lug is now more of a triangle shape than rectangle. Hope this help! |

After dragging my feet for a long time, I finally jumped into the pool myself... could resist the discounted/free shipping deal last week.
I have a lower on its way to my FFL and an upper on its way to my house. Interested in seeing how this thing plays out.

So I'm semi new here in as I was active once awhile back and then lost the old account info. Anyhow, I decided to mess with building a KS47, and so far I've really liked the firearm. i went into the build with the mindset of if it works then that is awesome and if it dont...well I can still make most of my money back off armslist.
So far, after 500rds down range with out any issues, I decided to strat building her up. Here she is in its current state, still trying to decide what to replace the basic magpul furniture with. 
That being said, my only complaint, is whomever put the barrel nut and set screws for the gas block on should never touch an AR again. They were put on ludicrously tight. It required a touch to loosen the barrel nut and I had to drill out one of the set screws after it broke two of my bits and mangled an allen key. |

I know your not a fan of pics but could you post one anyway to make sure I'm doing this correctly. I'm about to send this junk back if I can't get it to function correctly. I run and gun with my rifles. I shoot prone and around object which in return means the mag could rest on something or bump another object. It's absolutely crazy to own a gun that jams or has the bold get stuck when you place pressure on the mag. I own 11 other ar15 and have shot them for personal and military scenarios and never once have I had an issue with a magazine not feeding bc it was bumped. I like psa but it is not an acceptable excuse for them to tell us a magazine is not designed as a rest or grip. I under stand that but for the ones who use thier guns for more than bench shooting it really messes with preformance.
I just ordered this gun and got it in Thursday. I was super stoked about shooting it only to find out it jammed on it on almost every obstacle I tried to run it through. My buddy has the mutant and has never had this issue. I have used psa in the past and would rather keep business with them but if this can't be corrected then I don't want this gun. I will go to a mutant and call it a day. I'll be reaching out to psa on Monday to see if there is anything that can be done about this issue. If not I'll ask for a refund. I didn't buy this gun to bench shoot. I bought this to hunt, and run courses with it. It functions fine while standing up and nothing hitting the mag but that's not acceptable to me. If I can shave a little off the bolt and have it function then I'll go that route. |
|
I'm using p mags and also some type of steel mags I have left over from my ak a few years ago. I'm not sure of the brand.
I shaved and sanded the p mags. It cycles flawless unless you put pressure on the mags. This could be my favorite gun, even more so than me BCM and noveske guns. I really really enjoy the x39 but this is crazy |
|
I've got a KS-47 as well, but haven't had a chance to get out with it yet. After reading the trouble some are having with mags, I've picked up a few different brands to try out and so far the ones that fit the best and look like they'll be the best as far as the bolt not dragging on the feed lips are the Bugarian polymer (with steel reinforced lips) and the CAA 30 round (CAA mags @ PSA. The Bulgarian mags have a slight drag, but the CAA mag actually has no drag at all on the feed lips by the bolt, even when resting the gun on the mag. The CAA mag fits snug in the magwell with absolutely no wiggle to it. Again, this is all dry fire evaluation, but it may be something worth trying.
When I do finally get out, I'll report back. I'll be using Tapco, Bulgarian polymer (30 & 40 round), Magpul Pmag gen 2 and CAA mags for comparison. |
| I'm new here, but read everything I could find on the KS47, before posting. Just built up my KS47 lower after buying the kit on Black Friday. I have built multiple standard AR lowers before but never had left over parts...but I have a small set screw and a roll pin that is approximately 5/8" long that I just cannot figure out where they go. The lower functions properly, the upper came completely assembled. Any idea where these parts go? I looked online for assembly instructions with no luck, so I just assembled like I would any standard lower (without the mag release and bolt catch). TIA |
| What lead to the 16" carbine gassed Classic rifle kit going on closeout for $300 shipped? I don't think I'd seen that one before, usually the carbine gassed uppers have been heavy barrel. That's probably the cheapest AR rifle kit I've ever seen... almost wish I'd picked up more, to flip. OOS now though. |

I really wanted the mid-length but it went OOS last week. Any reason why it was marked as "clearance"? |
|
Does the basic AR-15 rule apply? Meaning does the longer gas system somewhat soften the felt recoil pulse on the KS47? On the same line, I wonder what putting an A2 tube, buffer, and spring would do to how the gun feels...

I don't see why it wouldn't, but 7.62x39 has less chamber capacity vs bore so it generally needs a shorter gas system than 5.56.
Somewhere in between carbine and A2 would be the VLTOR A5 setup, they have some very heavy buffers available for it but it doesn't make the gun as much longer as a rifle tube. I'm really curious as to quality of these Classic kits. I too would've preferred midlength, kinda kicked myself for not ordering it at $400 shipped on Black Friday, but this one isn't the same kit as the carbine kits that I've seen before. I prefer a medium profile barrel to a heavy barrel on a gun like this. |

Notice how they've been machined or ground down so they slip over the feed lips. This is exactly where the bolt hangs up on the mags. I contemplated doing the same to mine, but I want to get some rounds through it before I start removing metal. This mod should eliminate the issue.....nice work. |

I have a dremel I could use but I don't want to take off too much I viced mine in a milling machine but, don't think you will have any issue with more material removed. I actually removed I bit more material from my bolt than the one pictured and have had no issues since. |

Does the KS-47 require the hybrid bolt carrier group or can any 7.62X39 BCG work?
So, if I understand this correctly, the bolt carrier is cut to accept AK mags in the KS47 lower receiver. A regular 7.62X39 BCG would be used in a rifle that uses a regular AR lower and AR style mags. |

I'll wait for your range report before i purchase some. I have to break this into 2 posts due to the arbitrary site rules..... I was finally able to get out to the range yesterday and wanted to give an update. This was my first time shooting the KS-47 and I tested it with Wolf & Tula steel case ammo and tried the following mags: Magpul Gen2, Bulgarian polymer 30 & 40 rd, Tapco & CAA. My rifle was assembled using a blem lower and the 16" midlength carbine rifle kit. I started with 10 rounds in each mag, just to verify function of the gun. Shooting off the bench using a bag for a rest (not the mag), the Magpul and both Bulgarian mags functioned without a problem. Surprisingly the CAA & Tapco would not feed at all. Both mags locked into the gun, but I could not get either to strip a round off so neither of those was tested any further. After spending some time with those mags after I got home, it appears both are not seating high enough into the upper to allow the bolt to strip a round. I sanded the tops of those mags to get them to better fit, but won't get time to test them out for a while. 
|
|
Next I loaded each of the mags with another 10 rounds and shot off the bench and rested the gun on the mag. I experienced some FTF with the Magpul and Bulgarian mags using this method, but not every round. As has been posted numerous times, the 4:00 and 8:00 lugs of the bolt drag on the mags. After this I loaded the Magpul and Bulgarians to full capacity and shot off the bag. None of the mags would feed when fully loaded, not unlike some 5.56 guns I've shot. I ended up stripping off a couple rounds from each in order to get them to feed the first round. After that, no failures when shooting off the bag or standing.
Here are a few pics showing the wear on the mags: 
I think the fix for the issue is to remove some material from the 4:00 and 8:00 lugs on the bolt if you want to rest the gun on the mag when shooting. If you don't have a need or want to do that, then the gun functions just fine. Overall I'm happy with the rifle. Accuracy seemed good though I wasn't necessarily shooting for groups. Recoil is noticeably more than a 5.56 rifle. I'll probably try a heavier buffer and possibly install a muzzle brake. For what I have invested in it, I'll definitely be keeping it. |
