I picked up this thing in late 2010 when Sportsman Warehouse had the $800 deal. Unfortunately I was unable to put the thing through its paces before the one year warranty expired due to school and work obligations.
My only problem is that the accuracy fucking sucks. Terrible groupings with every ammo I have used. I replaced the hand guard with a free-float and that didn't help. The only other ARs that I have experience with are .556 and I've never had an accuracy problem before. Anyone else have these problems? Solutions outside of replacing the barrel? |

Have you tried a Lead Sled or another shooter? If so, then barrel replacement is all I can think of. No lead sled, but I have had two other people attempt to sight it in with the same results. I guess it could be me and them. Like I said, I've never had this much trouble with any other ARs or other guns for that matter. |

Are you using iron sights or are you using some type of optic? What is your average group size and at what distance? If you are interested in replacing the barrel you might want to check out Rainier Arms. They have a very good selection of 308 barrels. Using a Nikon Buckmaster 3-9x40 in a PEPR mount. The grouping is so sporadic that I can't really give you a number. I have tried sighting in at 100 yards. I get on paper, but it spits rounds all over the place. I'll look into Rainier Arms barrels. Thanks for the suggestion. |

Have the crown recut. Are you sure its not you rather than the gun? What do you think it would run to have the crown recut? ADCO charges $30 on a disassembled barrel. $50 fee to take the upper apart and put it back together. Thats $30+ship both ways+ a box and packaging. Its not a guarantee thats the issue. I would buy a new barrel and sell the old one. Someone might have better luck with it. |

Thats a hell of a lot more than a recrown and shipping, and more often than not its the crown; regardless ADCO can check it and the bore and chamber. Nobody is going to pay squat for a barrel that wont shoot. |

If its a barrel problem that cannot be fixed, it will need to be replaced anyways; then you added to the whole mess. It just like any decision. Possible problem, possible costs, and most importantly your time. |

Very strange-
Kinda reminds me of Jeff Cooper in a reply to a Steryr scout rifle that would not shoot. Try some Federal 168 match ammo for a buck a shot,if it does not shoot somethings wrong. garbage in garbage out. Use a known accurate scope and a good mount,make sure you are shooting off a good bench rest or bipod with sand bags in the rear or up front if you are not using a bipod. Check out the barrel and see if it is loose,call the company and arrange to send it back!!!!!! you might have to break that sucker in,shoot 5 then clean then shoot 10 then clean.(abreviated break in ) Hope this helps John |
| Take it back to Sportsman's Warehouse. I used to work there and they buy a crap load of products from vendors like Remington who owns Bushmaster. I used to send the customers' guns back even when it was "out of warranty" and they still fixed them. Never had one came back with any notes saying "out of warranty". Just make sure you didn't tamper with anything that will give them a reason to deny the repair. |

Seems so simple that I should have thought of it. I'm going to try that this weekend. And pick up some match ammo. Thanks. |

All of the sportsman's in Texas closed due to financial issues. I don't think that's gonna work for me. |

I was having accuracy issues when I 1st got my ORC. Couldn't figure it out & got frustraited. I had been running a Primary Arms single bolt offset mount & a KonusPro 6-24x44. I think the heavy scope & flimsey mount was getting pounded by the recoil. I Changed the scope mount to a cheap set of Weavers Quadlocks on top of the risers that came with it. Went from 6" groups to 1-1/2 - 2" groups. I used a ton of Radway surplus to break it in, then cleaned the heck out of the barrel (altough its chrome lined), put some 168g Hornady match thru it and it does fine (inch or so with a pure sh_t trigger). I think the barrel likes heavy projectiles as several commercial brand 150g didn't seem to do as well as the 168g.
I'd go one fix at a time & start dialing it in - Good luck. |

Stumbled across this thread and thought I would add my 2 cents worth.
As others have mentioned perhaps the best thing to try is different mounts and/or optics. Not necessarily the cheapest but what can you do. You can actually re-crown the barrel yourself very easily. Just Google recrowning. Larry Potter from Midway has a Youtube you can watch and he uses a drill, round head brass screws and lapping compound. The way you make it sound however doesn't sound like the crown is the problem. Also although free floating a barrel is typically good for accuracy most common shooters will probably not notice much difference especially at only 100 yards. Although your problem could be something simple you just as easily could have gotten a crappy barrel. They do happen. I know that's not what anyone wants to hear but......... The barrel itself could have a improperly cut chamber. I know you replaced the handguard, but did you have to remove the barrel or check it for looseness? As others have mentioned ammo is important but again the way you make it sound this doesn't sound like an ammo problem. And as others mentioned unless you are a superb shooter using a gun vice or proper shooting rest, front and rear support, will help eliminate any shooter error. Hopefully an optic and/or mount swap will solve your issue but if not I'm thinking barrel issue. |

Tried this weekend with a known good scope and mount. I also bought some match ammo. No dice. Thing still shoots like shit.
The barrel was not loose when I first purchased. I checked. And it certainly was not loose after the hand guard swap. Next step is to remove the barrel and inspect it. Crown and chamber. Looks like I'll probably just buy a new barrel if I can find one in stock. |

Just another thought! You bought the gun while Bushmaster was still Bushmaster I assume. Or it might have already been bought out by Cerebus/Freedom Firearms Group. I think they(Bushmaster) had a one year warranty but not sure what the warranty is now. You might try calling Remington and asking if they might do warranty work for you. It's certainly worth a try. Since the company was bought out they might still honor any possible warranty work required, depending on how long they choose to warranty now. You could always use the excuse of the company transition and not getting any customer service.
Oh and although it's a Bushmaster I believe that DPMS actually made the rifle. They were/are under the same parent group. I think you might have several "possible" options before having to buy a new barrel. |
| My .308 ORC with a RRA one piece scope mount, Zeiss Conquest 3X9 scope, and 155gr TAP ammo is printing three shot groups at .788 at 100 yards. At first mine didn't like ANY ammo but after a couple good range sessions/cleanings and finding a round it likes I'm very pleased with it. If it had a better trigger I'd bet my groups would improve too... |

Sending it off to someone equates with a trip to a good smith, only with the smith there's no shipping, just the drive there. Borrow a good rest to shoot from, shoot quality match ammo with the iron sights, don't even try to adjust the irons, use a large piece of cardboard, and just shoot for a group by shooting at the same point, regardless of where the rounds hit. If it shoots a good group, regardless of where the rounds impact, it's not the barrel. Start at 50 yards with the irons, If you aim at the same point and the rounds are all over, you should then look more closely at the barrel. Regardless, I'd still have a smith check it before rebarreling the rifle.
Just my 2 cents! |
