Hi im a new member ive been looking on the site hoping to get an hesse ar15 .223 and now i have one but its already having problems..i went to go test her out and it got about 2 shots off and then quit working..i come to find out later with some help from reading around the website that my buffer retainer came out.and it was stuck in the bolt carrier and the bolt wouldn't fully go back into the carrier.So now im trying to find out how that problem happened and what i need to do to fix it.Thanks for any help. |

The buffer retainer pin in is held into the lower receiver via the end of the receiver extension (the buffer tube). If you are using a carbine stock on the build, then chances are you did not screw the extension far enough into the receiver for the end of it to retain the pin. Also to point out, with some of the cheaper units being sold, you may need to trim the end of the tube a half thread so it indexes correctly for the butt stoke and the end of the tube lip to be just short of the kissing the inner buffer retaining center post (tube lip over the top of the outer ledge of the pin). Now if you have a standard A-1 or A-2 stock on the receiver with the receiver extension tightened correctly, and the buffer retaining pin is escaping, then the buffer retaining pin channel was milled too far forward in the receiver, and the lower receiver is out of spec. Since sending the lower receiver back is out of the question, then the solution to the problem would be to set back the locking shoulder of the receiver extension to allow the tube lip to protrude deeper into the receiver cavity, and if needed, you may have to mill the back of the tube cavity also for the correct buffer, B/C rear ward travel as well. Hope this helps, and welcome to the site!!! |
| well it was shot before and screwed it in pretty tight like it was pretty hard and i thought i might brake it and ya i havnt seen too many good things about the hesse but hey it was only 500..is there a pic that shows what it should look like when its screwed in all the way..and ya i think i have the a2...is that the adjustable one. |

The telescoping stock is the carbine unit. If you have this type of stock/receiver extension, then you will need to loosen the receiver extension castle nut and screw the tube in a turn or two to capture the retaining pin (over the top of the outer ledge of the pin, and just short of kissing the center post). Also as pointed out, you may have to shorten the end of the tube a 1/2 thread to get the tube to work correctly. |
It's like your first piece of ass gives you syphilis...
Thanks Dano523, i will do that once my parts came in...and i ordered them from dpms..
hahaah...and so i take it i kinda got a piece of shit on my hands...is there something i can upgrade to fix the problems these guns have..and thank you to the rest off yall that helped too... |
more like "cause its a Yugo"  Seriously...listen to the guys above...you'll be bucks ahead to dump it and go with a quality platform (ie Colt, Bushmaster, RRA, CMMG, LMT, etc) |
|
damn now bustin on the yugo...lol thats the other gun i have...so what do yall think i can sell that pos for then..i bought it for 500.. and im just wanting to know just to know too why they are so bad..i keep doing searches for hesse arms and i dont come up with much. |

Hesse Arms is(was?) notorious for low quality weapons...much the way Century Arms is in the FAL community. Out of spec, non-mil spec parts being the norm... Can't help you with the value question...most knowledgeable AR-15 folks avoid Hesse, American Spirit Arms, etc etc like the plague. |

Here's some pics of my buffer tube and retaining pin on my 6-pos stock: This first pic shows the tube screwed in as far as it will go and still clear the retaining pin. Note that with my 20" HBAR having it screwed in this far prevented the bolt hold-open function to work on an empty mag (no other function problems).  Here's the same tube backed off one revolution. It's barely holding the retaining pin in and looks like it's going to allow it to pop out at any moment but I've had zero problems. Backing off one turn solved my bolt hold-open problem.  |

FredMan, You can solve the bolt hold open problem by slicing off the needed distances from the buffer bumper. Just mic the current distance with the bolt face as far back as you can pull it with the charging handle to the back of the ejection port, then subtract 1/8" from that number, and remove it from the tip of the buffer bumper. Worse case is if you do decide to trash the out of spec receiver extension, you just have to replace the buffer bumper back to a standard un-mod'd unit. Also to point out, depending on the end of the receiver extension itself, when you mod the bottom of the tube (either slotted or just shortened), remember that you will need to cut back the top of the tube as well. On standard in spec tubes, the bottom of the tube is longer, and the upper section is radiuses to match the contour of the inside of the lower receiver threaded section. If the upper section of the tube is not mod'd back (read flushed with the inside of the back threaded section), them the protruding lip of the tube will back the upper/carrier from cam'g into place when the upper/lower are positioned together. |
What kind of receiver ext is that? |
|
It's one of the cheap units (the $29 specials) that are not thread indexed correctly. The slot you see in the end of the tube was slotted by FredMan to allow the tube to index correctly (retaining pin verses the butt stock indexed correctly). The slot works, but as noted in his post, with the tube out of spec, you have to mod the buffer bumper as well or the bolt face will not retract back past the bolt catch. As for the special, I don't see the savings in the long run, since what few dollars you save up front, is lost when you have to add in your time reworking the end of tube and slicing on the buffer bumper. |
He's referring to the "Yugo" car...a POS import from the 80's was it?..anyway the bright side is you can keep your SKS...the Yugo is top notch!  The Hesse has got to go though...
