MidwayUSA is selling a clone of the "D-fender" D-shaped extraction enhancer.  I saw Midway's price and couldn't believe they were selling the original model that cheaply.  I e-mailed, and they confirmed it's a clone.

Now, personally I don't think the original D-fender is worth its asking price.  I prefer heavy-duty extractor springs, which have worked perfectly for me.  That said, nobody who invested this kind of money developing the product (I admit, the D-shaped thing is neat, I admire the engineering) should get ripped off.  Is this patented or anything?

I searched arfcom for "Defender" and "D-fender" but didn't find a thread on this, or the manufacturer's username.

Lowes, Home Depot, Ace, Tru Value.

armforte is the manufacturer

That looks just like the CMMG kit that I purchased a few months ago.

I do not have a real D-Fender. I normally use Adco CRANE o-rings anyway.

I have a dfender in one gun, and a Home Depot ring in another.. Both seem to be fine... Havent been able to get the Dfender to melt...

+1 on the real D-Fender
it's hard as a rock when you try to pinch it, and it's heat and oil resistant.

It's not a d shaped piece of rubber or o-ring.
