Can anyone tell me their experience with the D fender extraction ring? Does it help? Is it worth the $12.00?

I took the advise given by others on this board and ordered some increased power extractor springs from Wolff. Now my rifles work fine and will last a long time. You can get 3 springs for the price of the o-ring, and with the spring you don't need the o-ring. Fewer parts is a good thing.

I ordered one to give it a try, but was also told by one of the instructors at the NRA range to just go to the hardware store, buy some little donut/o-rings that would fit around the spring, and use those, as they are DIRT CHEAP and work exactly the same.

YMMV, $0.5 or $12....

I don't think I paid $12 for one.  I put one on along with the Wolf spring when I changed a worn extractor.  Check Numrich Arms and see what their price is.

[url]www.triplebreakproducts.com[/url] sells the Olympic X-rings which do the same thing only much cheaper.They've worked real well with my AR's but now I use the Wolff springs.

I agree with SMJayman.  I use the O rings sold at Home Depot and they work perfect for my shorty M16.

I dont like little rubber parts inside the operating parts of any of my firearms.

Get the Wolff XP spring.

I have a defender in my home gun and an Issue rubber O ring in my work gun, gotta loose that ring on the work gun LOL.

I would say go with an issue O ring if possible.  It has been heat tested while Home Depots probably has not.

If someone is interested in a heat resistant O ring, Viton O rings are rated to 400 degrees F and are resistant to harsh chemicals.  I thought if the Home Depot O ring melted, I would stop by the local supply house and buy the Viton.  But, I haven't had to do this yet.  Small Viton O rings are less than a dollar.

Ive never needed it in any of my AR's. Now, if I did, I'd get the Viton rings that Dan mentioned. They are chemical and heat resisitant, and have used them in my old 1966 Corvair with great results.

Band-aid used to keep a rifle running.

Bottom line is that it's better to fix the problem with the rifle, then to over power the extractor spring to mask the real problem.

Mik,

To answer your question, I have three of the D-Fenders in my AR-15's. They work fine and I have had no failure's to extract. However, none of these guns had any problems before, so I really can't tell you they made any difference.

Thanks for the info guys, I'll go with a Wolff, and try just that before going to the D ring.[:D]
