Hopefully that resolves your issue...definitely seems probable.
10.5" ar huge groups? RESOLVED
- Thread starter SksA1
- Start date
Fingers crossed, hope that's just it... I think when I built my DMR, after the first trip out, I came back and rechecked everything to make sure nothing moved or loosened...
I have MBUIS on it already....havent sighted the in but should get the point across if need be
I purchased an S&J 11.5" barrel from SFRC. While installing the flash hider, torquing and removing to get proper washer for orientation, the barrel came out of the barrel extension. Might want to check yours for this flaw, hopefully it is isolated. Thankfully I never shot mine before discovering this very dangerous defect.
I have sent the barrel to S&J at their request. It arrived there Jan 31, 2013 and have not heard anything.

Uhm, if the extension is loose - send it back.
Odds are if you tightened the extension back on - the gas port will not line back up, nor will the headspace be correct (in all likleyhood).
Once the barrel extension is torqued on, the barrel index pin is set - this is drilled and inserted thru the extension into the barrel as well.
This is a factory warranty issue IMHO

Well i tightened the barrel back on and the flash hiders is reinstalled....now you guys have me nervous!!!!,
I bought the barrel from the EE and it was brand new! But im not the original purchasee so i doubt they will accomodate me!?
I forgot my rifle today (was in a rush this morning) maybe its time to email S&J!
Edit;
I sent an email to S&J and informed them if they wanted the barrel back i dont want to wait for a repair and id preffer a replacement

Good luck with an answer. I sent my barrel back to them (at their request) at the end of Jan and they still have not replied to any emails or phone calls. My barrel extension came loose before ever being fired.
Just got an email!!!!
I guess im buying a new barrel!! And no compensation
So i ordered a chrome moly government daniel defence 12.5
THE EMAIL I RECEIVED WAS A MISTAKEN REPLY AND WAS NOT THE VIEWS OR OPINIONS OF S&J HARDWARE!!! PLEASE EXCUSE MY MISTAKE

Really? They are not either giving you a replacement or a refund?
They gave one to my friend not two weeks ago.
The reason it's loose is because they nitrided the barrel after the extension was installed. With parkerizing, it's okay to do it after installing the extension, but with nitriding it seems that the heat (and difference between the hardness of the barrel and extension) causes it to come loose.
You could try re-torquing the barrel to 150ft-lbs but it's unlikely the gas port would line up properly :/
Perhaps talk to the original owner ? - $20 to them, may be enough.. Just a thought.
My thoughts exactly... That's piss poor customer service if I've ever seen it. As a dealer myself ( not firearm ) I couldn't imagine not warranting a known issue. Original owner or not.
