So I figure this is an easy fix but to be fair to my friend I wanted to ask you all if my proposed solution will fix it. He blatantly ignored my advice to buy a BCM and bought a dpms instead for the price of a colt mind you.
Out firing the other day we brought steel cased ammo. Cheap at cabelas so don’t burn me. Anyways the gun cycles the fmj fine but sticks casings and blows primers on the HP stuff. Now I know that its Def the ammo there but my first question is if Ned’s 5.56 reamer would fix this? My next question is if someone nears south Dakota would be as so kind to let me borrow theirs. Or if someone would be willing to mail one to me for his barrel?
I do understand that the moral of this story is friends don’t let friends buy crap ars.
Man you are fast and I Dang sure appreciate your help. I established that it is a 223 chamber so I can’t use your gauge much. I hope I didnt waste your time tho.
I hate to break the news to you, but that gage will do nothing for the issue. You need a true 5.56 chamber gage like Ned C. makes. You insert it into a clean chamber and if it sticks then the chamber is too tight.
If it falls free then it is a 5.56 chamber. FWIW- I have personally checked DPMS barrels and they are tight.
The chamber reamer removed a fair amount of substance from the chamber. Don’t assume that it is the ammo. Blown primers and stuck cases are all signs of tight chambers.
Right I assume that the problem is more the barrel actually. I was talking about how it cycles the fmj stuff and not hollow points. Same brand and weight but the biggest thing is the chamber.
I was hoping someone would possibly have neds reamer near me but even the gunsmiths around here. It’s amazing that I live 20 miles from places like black hills ammo and carbon as well as a number of custom rifle builders but am still having trouble finding one. I try to stay with quality barrels so I have no need to buy one. I was hoping someone here had one to rent.
When I refer to the barrel I am actually talking about the chamber. Some people believe that the reamer will cause harm. I’m not going to get into that. But, the alternative is either sell that barrel and get a real one or accept that you will have to yest your ammo out every time to make sure it works.
I too meant chamber when I say barrel. So IG I know your position on dpms but are you saying its the wrong move to ream the chamber and instead you would just buy s new barrel. I have told him that eventually needs to do that but it is unlikely to happen now. He and frankly most around here lack the tools to change a barrel. I could do it by jimmy rig but if its not a dire situation would rather not. He already feels taken after I showed him what he could of had for 1400 bones. I think his only option is a new complete upper or to salvage the barrel he has and ream the chamber. Which worst case scenario is to have to buy a new upper anyway. I should of mentioned the circumstances better. He’ll go with my advice and i’ll go with someone like yours.
Not wrong, but economicaly it doesn’t make sense. The chamber reamer costs 240.00 and that’s alot for a one time use considering you can get a good barrel for close to the same.
If you can locate one or have someone do it for a fee then by all means.
Def why I’m hoping that someone is willing to rent or loan me one. No way am I buying one. I will stick to known trusted manufacturers. He didn’t get taken to the cleaner too much he also got a bsa red dot. Lol
Send me the entire upper and I’d do it free of charge so long as you/he pays the return shipping of the upper. I’d also remove and remount the carrier key and install better screws and stake it correctly. I recommend using a BCM SOPMOD extractor upgrade kit also which includes an extractor, ext. pin, ext. spring, black ext. buffer and o-ring and a new set of gas rings.
I had a similar problem with a Bushmaster barrel. Despite being marked 5.56, it was, in fact, a .223. I considered various options and instead of trying to fix the Bushmaster barrel I simply purchased a new BCM 14.5 mid length upper with a hammer forged barrel, permanently pinned PWS, with LaRue 12" rail. And yes, the BCM is perfect and I could not be more satisfied.
But I have a question: is it possible to use a reamer on a chrome lined barrel? I have read in one of the AR books by Sweeney that the chrome lining is harder than the reamer, that reaming the barrel is not possible, and in fact, will only destroy the barrel and reamer. Is this correct? Will the reamer indicated modify a .223 chamber into a true 5.56 chamber without destroying the barrel and reamer if the chamber/barrel is chrome lined?
I do wonder if dpms/bushmaster/etc. engage in class action fraud for selling barrels marked 5.56 when they know (or should know) that they are not?
At any rate, I recommend that the dpms barrel be treated as garbage, disposed of accordingly, and that a quality barrel/upper be purchased instead.
Robb for some reason my phone won’t let me pm you but thanks. My buddy said Hell yes to your offer. Instead of sending it I think I might just bring it by as I have to head back down to nc and its only a minor detour from SD to there. That is if nova is still where your at which I don’t doubt.
Yes in Manssas VA, I’ll be of wild boar hunting in FL and will be back the 14th and 15th and then off on vacation the following week. But you can drop it off and I’ll get to it when I’m back.
Ghost__1, I was having similar issues with a CMMG upper. Took it to VA Arms and after quite a bit of chamber material was removed, it’s been good-to-go ever since.
I Def do appreciate the help with it from Robb. I also didn’t mean any disrespect Ned by saying I won’t buy one. Kinda hope I don’t need it after this. FWIW I think that its probably saved countless folks some trouble from out of spec barrels. Pretty ingenious.
Ghost, no prob at all-- I know $240 ain’t cheap, especially for the guy who has only one chamber to do. It’s more for the guy with a ton of AR’s and friends with tons of AR’s or some one managing a whole fleet of them for an agency. I’m glad you found a place to get it taken care of.
