I'll be honest and say I don't own an OBR... I assume they still have the pins to hold the upper and lower together? If so, take a punch and a hammer to the pin you're having a hard time with. Be a bit "gentle" (as gentle as you can be with a hammer) and it should pop out so you can get the lower off...

I think he's already removed the pins before trying to pop it open. My guess is its just really tight. You might call Larue and ask them if they have any suggestions.

My OBR damn near broke my leg when i popped it open. Just give it a bump or two and keep trying. I eventually got mine to be "just right"

My lite was much tighter than my tight as hell OBR 7.62.
I had to hold the upper under my left arm supporting the rifle with my left hand and pound down on the stock with my right fist to get it to open. Watch that you don't pinch your fingers between the upper and lower when it comes loose, it kinda hurts. 
Once you work it a little it will loosen up. Oh yeah, make sure your bolt is closed.

I found this topic funny/ironic (not that the OP is having issues) as my two good friends and fellow AR users, have been building a few FrankenARs (All good parts, just many various manufacturers) and they are always complaining about the looseness/wobble of the upper/lower..
The one in general has bought a whole different lower just because of the fit... Does a good job at building whatever he builds, but Hes really obsessive sometimes... I'm expecting to have the issue when I take my apart again as I had to put my ruberized Glock armorors pad on/around mine Upper/Lower and beat it together with a mallet to be able to put pins in... I'm guessing it'll be as tight comming apart... |

Less cleaning, more shooting should do the trick.

Ok here's what i've done so far...
Step 1: drop mag, unload, and check the chamber(hammer should be cocked at this time) Step 2: pull rear take down pin Step 3: place magwell on the soft arm of the couch Step 4: pound/press down on rail with one hand and the buttstock with the other... I thought about using a pine wood shim to wedge between the upper and lower, but i'm paranoid of marring the finish or tweeking something. I guess i can just shoot the shit out of it and hopefully it'll loosen eventually. |

I have several LaRue rifles in both the Stealth's and OBR variety. While they all have had tight lower/upper fits, none have risen to the level you are experiencing. Double check that you have released the bolt forward. If that does not help, I would just shoot it some more.

My OBR762 was so tight I almost had to use a dead blow hammer to open/close it, originally. It loosened up after a few trips to the range, though. My OBR556 is around as tight, but it should wear in quickly.

I am assuming that between steps 1 and 2 you are releasing the BCG back forward before you are trying to break her open right? If so she is just tight, my OBR was super tight and hard to break down the first couple of times but a piece of cake now. Just keep trying it will break free eventually. If you are not releasing the BCG forward please do so.

Maybe there's a burr on the takedown pin, make sure it's pulled all the way out of the upper lug....
Also, you might wanna try letting the bolt down (closed), if you haven't done so already... (if this is the problem, you darn well better admit to it... if you don't respond, we will know  ) |

Ha ha. The very first thing I said was drop the mag. That means when I pull the CH back to check the chamber, the bolt doesn't stay open. I have built 3 rifles from piles of parts, and while I'm no master gunsmith, I believe I know the AR platform pretty well. I'm not even going to dignify the takedown pin swipe. I was asking for solutions, not smart ass remarks. You sir can go f yourself and the horse you rode in on. I finally got last night. I guess I was being too careful and it took some more umph than I was accustomed to. Just was a little nervous to pound the he'll out of a fine piece of LT goodness. |

Put the stock in between your legs resting on the couch chair whatever and beat like hell on the bottom of the upper. It will come off and loosen up over time.

I had the same problem. I had to extend the stock, brace it under my arm, placed the barrel over my bed to stop it as it broke loose, and pound the shit out of the top of the rail with my fist. Finally brolke loose. At first I thought the bolt carrier had to be extending slightly into the buffer tube but it wasn't. I have since place the OBR upper on my KAC lower, and they fit very tight. I have to squeeze them together to get the pin in. But I'll take this tightness any day over my junk Spike's set where the upper literally flops around on the lower.
Cycle the bolt and tap the forward assist to make sure that the bolt is all the way forward, then pound away on the rail (not the barrel.) There is a small chance that there could be a bit of crud blocking the lugs preventing the bolt from fully seating. |

I've done that a few times... Not to long ago I spent a couple minutes cussing at a BCG when it wouldn't go in. I was on the verge of getting a hammer when I remembered to sling the bolt forward...  It was a long day at the range.

I watched one of my guys thrashing around trying to get one apart ... turns out much anguish later that the dust cover was simply closed over a bolt that was back.

Yes I was in a bad mood. Yes I finally pounded the shit out of it and got er open. Have you had one of those days when you're frustrated with other things but something totally unrelated sets you off? Well that was yesterday morning. It's done. I got it open. I was sick and tired of people stating the obvious noob oversights and blew my lid.
RDTCU: I have nothing against you or your horse. As you stated there were earlier posts but by the time I got to yours I was pissed. I can't stand the ones here on ARFCOM who belittle people because they ask a question that seems so elementary. And by stating the obvious, they are right 100% of the time. Stroking their own ego by kicking the shit out of people with a damn keyboard.

I'm pretty sure that phrase is standard dialect in the OK/TX region. You know I have actually had people from the edges of our country ask me "Since you live in OK, do you still see cowboys and indians?"
Me: "Yep I can see the teepees in the distance behind my house and i still ride a horse from time to time."
