I saw the thread on AR 15.com, but I want further clarification...
  1. Where is the best spot to start the cut using a dremel?
  2. Some say you need to cut in two places, some say you can finish up the cut with snips.
  3. I see the gas tube passes through a hole at the top of the ring - do you have to cut the gas tube free (better have a steady hand for that, I don't want to nick the tube!)
thanks!

Make 2 cuts at opposing sides and separate the ring in half. Cut at the sides, not near the top... just because the gas tube is there and you don't wanna chance any damage to it.

The gas tube doesn't go through a hole in the delta ring itself... you'll understand everything better after you make the cut. Don't worry, just cut carefully and slowly. Its quite soft, it goes fast.
 
This is going to sound dumb but can't you take the barrel off, dismantle the ring assembly and just slide it off?
I seem to remember putting a barrel assembly together from parts and I had to get one of those weird plyers to put the thingy in to hold the spring.
 
Get a barrel wrench & reciever vise block- you will eventually anyhow, so you might as well spend the cash now to save the delta ring (which go for around $30 as an assembly)

There is nothing much to re-indexing the gas tube, so don't shy away from it based on that.;)
 
Personally I'd rather sacrifice the delta ring assembly than mess with taper pins and headspacing. If the rifle runs, don't mess with the barrel. The loss of a Delta ring assembly is a small price to pay for ensured reliability and is much faster than removing the barrel.

Really??? So I presume you pull your FSB and gas tube off with a pair of pliars without removing the taper pins. Failure to tighten your barrel nut will result in a non functioning rifle. Either of these actions are not what I would call a good trade in exchange for a delta ring assembly.

TDC - before making any more comments, I would tear an AR down for familiarity. Eugene Stoner was one smart cookie on this rifle design - you can leave the barrel nut hand-tight (or looser) and it'll still function.
 
Holy! Misinformation abounds!

Remove barrel from upper, drive out pins in front sight base, the sight will come off with a little twisty motion. Easy, peasy and no cutting involved.

The only way you could screw up the headspacing would be if you misaligned the register pin to the upper register slot...pretty tough to do unless you are a total doofus.

I would however recommend that you have the proper AR holding fixtures before attempting any of this.;)
 
There's no pins holding the barrel having anything to do with removing the barrel or the delta ring set.

Ya don't need to remove the FSB to get the delta ring off.

The only time I'd worry about head space on an AR is if you mate barrels and bolts of undetermined amounts of rounds fired. Newer parts are good to go as is. That is, if you trust them to be in spec. :)

Plug 'n play baby! :)

You should really invest in the tools to get the job done right and develop good habits right from the start. Cost you 'bout 50$. ... and a vise if you don't have one.

Right, right.

I'm not disputing the design or the ability for it to function with loose or mis-aligned parts. my point was that wasting money on action blocks and f*cking with the factory setup of your upper to remove and save a delta ring is not worth the cost or aggravation. The risk of damaging your upper or its reliability is not worth the money saved. Who really removes the barrel of their rifle on a regular basis and why? There is no need to remove the barrel. Set it up, shoot it and leave it alone. Unless you plan on owning or working on AR's fairly regularly. The cost of the tools just isn't worth it.

.......Meanwhile, back at the ranch......, :jerkit:

I cut the ring off and removed the springs etc, and had no problems whatsoever, and have installed my new Samson floating rail... (thanks to Canucklhead!).

Thanks for all the advice guys! :)
 
Cut it. Don't cut it. Cut it. Don't cut it. ...

Scares me to buy stuff sight unseen around here when I hear these things being done to guns.

Tsk, tsk.

That's what good, detailed pics are for. If the best a guy can do is a single, poorly-lit, blurred shot - shop elsewhere.

One man's "pristine" is another man's "modified front site", so pics are your friend.

And yeah, taking a barrel on and off an AR is simple with the right tools, usually simpler than taking off an FSB with taper pins if some of the threads on that task are accurate.
