I've had my 16 in 7.62 OBR for about a year now I'm haveing a continuing problem with the gun short stoking ,I have call back to Larue and explained the problem and their answer was sending me out a light buffer spring. After shooting the gun today the problem still is there I was wondering if any else has had this problem and if so how they fixed it I'm trying to avoid sending the gun back
Thanks for the input |

175 gr M118 long range and federal gold match 178 gr 100 rds though the gun it nights as well be a bolt action I have also tried multiple mags as well Sir, i have a 16" OBR that did the same thing. They replaced my bolt. That was all they would tell me. I continued to have problems while running suppressed tbough, and they finally replaced the buffer spring to a green one, which is stiffer. I now run the weapon on unsuppressed setting whether i have a suppressor on or not, per their instructions. The gun shoots like absolute dogshit with the suppressor, but great without. I have never sent it back for any addtional testing. |

So the gun came with the red heavy load spring and when I call and complained they sent me the shot white light load spring I guess I'll call back again with the same problem I kinda expected more from the company If they dont have the gun in hand all they can do is guess at what might be your problem. Could have trash in your gas port, could need a stiffer spring, who knows. Frankly, i dont see what is wrong with them accomodating your wishes and trying to fix without sending it in. They gave you a free spring to try. Since youve had the weapon for over a year and only fired 100 rounds i dont see wbere sending it in is going to cramp your style. No offense, but i dont see where they have done you wrong....yet |
| No trying to get into a measuring competition with any one, the problem I have is I work with guns for a living and when you purchase a rifle from a none mass production company that has the reputation in the sniper community that it has you would expect an issue like cycling and clambering would be QC prior to shipping to the customer . It would be one thing if it was just me but talking to people it seems to be a some what common trend. And when you pay that price tag it suck to have to send it back |

Lets start over. You should send the gun in. They are good people. They will make it right. I know it sucks to bave problems with an expensive rifle but shit happens. Let them fix it and save youself the frustration.
Aside from that, can you specifically describe everything thats happening? Does it always extract consistently? Does it always short stroke or is it periodic? Do you ever have feeding problems where the spent cartridge wont extract and another round gets picked up? J |

I've seen a lot of issues with sprinco springs, enough to make me leery of them. I am using them in a couple of specialized applications, but for general use I prefer the stock springs.
I went to the Tubbs FW in my OBR on the recommendation of Caylen from Magpul. At their PR class my OBR would start short stroking every 40-60 rounds at which point it needed a wipe down and re-oil. He said his ECC would do the same until he put in the tubbs wire, and that afterwards the new spring also seemed to tighten up the groups a bit. I haven't had a chance to shoot it yet because I've been waiting on a new scope. |

J x2 Send it in or based on years reading this forum, call up and ask to speak to Fingar on the phone. Tell him in exact detail what the rifle is doing, I'm presuming he'll either then give you a remote resolve action plan, or worst case have you send the rifle to him, and he'll make it right. Also, what suppressor are you running on it, or are you only having issues/tested so far in un-suppressed mode? Call and speak to MF, if you don't call they can't help ya

| What stock are running? When I switched to a PRS from the collapsible I changed to a rifle length spring and it immediately started to short cycle. I called and was informed I should be running the stock carbine spring with a spacer and where I could buy one (they didn't have any in the shop). The spacer made matters worse until we discovered the one I bought was too long. LT had them back in stock, so they sent me one and the problem is solved. |
If it is short stroking that is indicative of too much recoil spring pressure, or something else being too tight. I could also mention substandard ammo pressure (.308 vs 7.62) but you mentioned both types of ammo. The chamber could be a little tight, so the lube will help, the bolt cold be a little tight, so again, the lube will help until normal wear loosens things up. Also, a stiff spring in the magazine could be creating just enough extra drag to cause short stroking.... I've actually had that problem before. An extra-heavy buffer can cause this issue as well. In the weapon I had short stroking issues with (non-LaRue) I swapped from an Endine hydraulic buffer to a standard carbine buffer and the short stroking issue with my problem magazines went away, that said felt recoil was noticeably higher. You could also try a lighter buffer spring and that should help.... (I think you may have mentioned doing this already, I'm just having a senior moment)

Well,I think you need to bite the bullet so to speak and send it to them.
My Ptar 7.62 was short stroking from the day I got it. Tried many combos of ammo, mags, oiling etc. Larue said send it back on their dime < I only had it a few weeks>. The turn around was astonishingly fast. When the Ptar returned it had a different upper. I am not an expert and know it was a completely different upper because they told me so. When I asked what was wrong with the original upper I never received a definitive answer. In the end a satisfactory experience for me as it now runs all ammo and mags with no secret oiling rituals. Good luck and I hope things work out. |

After firing 15 rounds, I quit. I described the problem in detail (including what brands of ammo I tried, that I had oiled up the gun really well with slip2000, types of mags I tried, where the brass was ejecting--when it was actually getting ejected, what buffer was in the rifle, the bolt wouldn't lock back on an empty mag, etc.) and sent pics. The person at LT that I spoke with and emailed told me they would send me a new BCG and for me to return my BCG. The rifle has been working flawlessly since then. After they received my BCG back, I was told by the person at LT that they had no idea what was wrong with it. Just by looking at the 2 side by side, my untrained eyes couldn't tell any difference between the two other than the functioning BCG was still magnetized, but the one I returned was not. I spoke to another person with an OBR several months ago who experienced the same problem with his OBR. And....this past weekend I was at a long range class and had someone tell me that he had the same prob with his OBR and someone he knows also had the same problem. All those were fixed with new BCGs. So....see if they will replace your BCG. |

That's a lot of malfunction for a 3500 rifle..... Taking mine out tomorrow for its first date, will let you know how it runs on m118. Sure is! Ive seen bigger cf's on better rifles though....hopefully they had a bad batch of bcgs or bolts. My repair said replace bolt-bring rifle back to spec. No idea what that means. Of course, tbey wouldnt elaborate. J |

Especially since the BCG was the only thing that was replaced on mine (and the few others that I have spoken with) and they have been shooting great since then......no probs with mine starting with round #16! |
