Sorry for the delay, had camera problems.
My $.02; It's a nice adapter and looks as nice or better then the pics that Renagadebuck has up. The mag release button does sit out to the side a little more then I thought but it functions, I see no real problems with it unless you abuse your firearms.
Now the only down side, if you are one of those people that have trouble turning a screw, this will be a hard project for you. If you understand how to work on stuff then it's just doing some grinding/cutting of the lower part of the trunnion just inside the mag well, the mag opening on the rifle doesn't need modded at all.
It does work and works very well, I put a few mags through the rifle last weekend and had no issues with it.
Now I did see a post somewhere on another forum where someone modded the front of the mag but cutting a little off the front corners, this would require less work on the rifle but I don't know how well the mag would hold up over time. But then it might not matter since the AR mags are really cheap right now?
This is a pic with a 20 rnd mag in, it all I had near me at the time.
I'll get better pics later
