I'm going to try the Faxon barrel as is. I can always dremel the feed lips if there is a problem. Gibbs makes a side charger upper, but its almost $300. My complete PSA upper (w/ barrel, BCG, and hand guard) was $450 with tax and shipping. I do have a billet upper sitting around. So once my KS47 upper arrives, I can compare the two and see if it can be easily modified. |

Finally fixed my vise set up and got angry enough to get my barrel nut off. Bare threads and had to have taken 200 ft/lb to break free
With an adjustable gb and full time suppressed, what buffer weight and spring do you guys like for the platform? |

I use a Sprinco Orange (Extra Extra Power Spring) and H3, and I’m still a little over gassed when shooting suppressed.
I’ve just learned to live with it. |

Are you running adjustable gas? I have a variety of sprincos handy but I don't think I have an orange.

Been using my secondhand KS-47 for a couple months now and loving it.
I'm sure it's been covered, but I'd rather not review 27pgs, will any ol' x39 AR bolt with the .125" bolt face depth work with the modified KS-47 carrier? I'm looking to grab a space .125" bolt for this and another x39 AR I have, but PSA only sells the bolt and carrier as a combo. I understand the carrier has been modified, but I'm not worried about the carrier so much as the bolt. Figure if the carrier is wrecked the entire gun is probably down, but I like to have a spare bolt and/or a bolt rebuild kit with me at matches or during a hunt. So, could I slap a Maxim .125" x39 bolt in the KS-47 carrier and be good to go? |

Ah, thought it was just the carrier which had been worked on to clear the AK mag. Why doesn’t PSA just sell a bolt? The extractor is a standalone part you can purchase. |

I agree, a spare bolt covers the extractor and broken teeth problem. @PalmettoStateArmory any chance you can sell a complete bolt without the carrier? I would definitely be up for one.

I put in a warranty claim on my KS-47. I had several light primer strikes on the first 50 rds fired. Its been a week and i have not heard from anyone. |

Not sure if the discontinued LMT Enhanced bolt was also modified, but I swapped the LMT from my DI ARx39 into the KS-47 carrier and the KS-47 bolt into the standard DI AR carrier and both worked fine with stripping rounds from the AKM mag and the ARX39 mag. I didn't put a caliper to them, but the KS-47 bolt appears to be the same as a standard, .125" bolt face depth, 7.62x39 AR bolt. The standard DI AR carrier did not work with the KS-47, but that was expected as it does need to be cleared for the AKM mags. I picked up a Maxim .125" bolt face bolt as a spare along with a .136" face depth Grendel bolt. I'll be sure to test fire the .125" bolt in the KS-47 and DI ARx39 when it arrives. |

If the bolt carrier is busted the entire upper is probably toast and needs replaced, but even 5.56 shears bolt lugs from time to time. |

What about them KS47 bolts for sale as separate parts?

I'm sorry Josiah/PSA I wasn't clear. I meant stripped KS47 uppers. I already have one of your built KS47 uppers and do not need another one. I like to use your KS47 stripped uppers in other builds with wider mag lowers.
Sorry for the confusion. Thomas. |

Anyone swapped the enhanced FCG for a Geissele SSA or SSA-E?
Picked up another SSA during the G discounted sale and would like to swap it out, but wondering if anyone else has done it and had issues setting off primers in the steel cased ammo. |

I'm sure someone has addressed this already in 27 and counting pages of thread text, but without a search function it sure is hard as heck to parse quickly: can a KS47 upper receiver be used with a mil-spec bolt carrier for a custom build (i.e., NOT using AK magazines NOR AK-compatible 7.62 bolt)? It is my understanding that the PSA KS47 BCG simply has cuts along both sides' lower rail-riding areas, but I thought that was to accommodate the AK magazines. In a custom build for a different purpose that isn't using AK magazines, would the KS47 upper itself impede mobility of a mil-spec carrier in any other way? Is that why the PSA KS47 BCG has a weird trapezoidally shaped rear mass, or am I reading into this too much/missing something?

View Quote Not sure I understood your question correctly, but I swapped my Gen 2 KS47 upper with bolt and carrier on to a standard AR lower and while the KS47 upper has a cut out for the standard BHO paddle, an ASC x39 mag wouldn’t lock into the magwell. Guessing the upper and/or carrier interferes with the STANAG mag feed lips. |

@PalmettoStateArmory
Weird suggestion (I guess) - I would love to see a bolt-action upper that’ll pin onto KS47 lowers. I did a bolt-action a while back using a Uintah 300BO upper with one of your KS47 lowers with a Velocity trigger and liked it (a lot). This was back when shorty bolt-actions were just getting hot. My main negative was I had to modify AK 5.56 rocker mags to make it all work, which it did but made the feed lips a tad thin. Would love to see a no muss, no fuss option that could use readily available mags without modifications some day. Here’s a pic of that creation and my little girl at the range squeezing a round off. Attached File Just an idea… ETA: If by chance you might consider it a possibility, hit me up for a suggestion or two. There was one area concerning upper design I really (REALLY) felt needed attention. |

So I just got my form 1 approved on my 8.5” KS47, so I can step a stock on it and add a foregrip. So I went to add a magpul RVG with the little 1913 rail with mlok attachment screw pieces. I can’t mount the rail with the mlok screws because the screws hit the barrel. There isn’t enough gap between the mlok railed hand guard and the barrel. Is there any solution to this besides dremeling down the lengths of the magpul screws that came with the RVG?

PSA, a couple of things:
1st, ditch the extractor o-ring. That's probably contributing to extractor breakage. It's a bad band-aid that came from treating a symptom rather than the disease in M4s. Think dropping a round into a pistol chamber then dropping the slide. I've seen ARs that malfunctioned due to excessive extractor tension. If the gas is right, one shouldn't even need the insert, only the spring. Along with the TC-E extractor, it should be much better. 2nd, look at the AR Performance 750XD and Titan bolts and extensions. I've wanted this in a KS-47 since day 1. Powerhouse PSA has done more extensive custom parts many times. This should be easy and could create lifetime bolts. Bonus points for incorporating dual ejectors like the new KAK bolt. Also, the lugs are already rounded, so might work fine with AK mags. Hell, if you really want the ultimate, go with Aermet alloy. These together could really cement the KS-47 as the ultimate 7.62x39 AR. Incorporate it all with the Jakl / KS-47 hybrid and BOOM! AWESOME!!! |

I have a KS-47 pistol and stripped the top screw on my handguard and have been trying to get a simple screw for weeks now from PSA and there telling me I have to send my whole gun in for a tiny screw is there any way I can figure this out without sending it in for a simple screw? It’s been the run a round for weeks now.

Hi all...Will take some time to dig through this thread as I'm sure this has been asked/answered
I'm running a Gen 2 KS-47, 16" barrel, suppressed. It functions just fine...however...when breaking it down to clean last night I heard rattling in the buffer tube and it appears the plastic bottom of the buffer had exploded into pieces back there. Any thoughts? Seems like it may be impacting the back of the tube violently. Would a heaver spring prevent it from smacking so hard? Apologies if this has been discussed already Thank you! |

Depending on the can you're using, you might need to increase the buffer weight and/or spring strength to slow down the bolt carrier. |

I just noticed primer marks on unfired rounds after being loaded and ejected. Anyone else having this? Can upload a pic later, just looks like a light primer strike but from only being sent into chamber. Thankfully didn’t fire but still seems sketch

Thankfully didn’t fire but still seems sketch View Quote I’ve seen that in a number of different t firearms that don’t have a spring loaded firing pin, to include .223 ARs. Never been an issue since the firing pin doesn’t weigh much and doesn’t have enough energy to actually detonate a primer just by contacting it upon chambering. Could also be that PSA uses a slightly longer firing pin to ensure consistent ignition of the notoriously hard commbloc primers in steel cased ammo. I had to put one in my first x39 AR years ago to get reliable ignition. |

Would anyone happen to know how much the PSA upper receiver weighs? I am wondering how it compares to the Gibbz side charger because im trying to shed some weight off my 10.5" sbr gen2 setup. I don't think I want to take my stock 10.5" upper apart in case the new upper didn't work out so I can keep the warranty on the PSA uper. So im looking at building one using a faxon 10" barrel with an adj gas block and lighter handguard setup.
What other uppers work other than Gibbz and billet rifle system? |
