Is it possible to put an MP5 grip frame onto a G3, or is there a G3 frame of similar style? I tried searching but it hasn't gotten me anywhere.

This is the one I'm talking about:

yes, you can use the mp5 or 93/33/53 grip frames on a 91/G3

there are G3/91 lowers but only real difference is it has a longer(2 push pin) tang.

So the MP5 trigger pack can be used. Nice!!

But whey does the G3 model have a dual push pin in the rear?

Don't know why for certain, but I'd guess it has to do with adding a bit more rigidity to the receiver. Gotta figure you're talking firing 7.62NATO vs. 9mm.

FWIW I bought a used Hk91 that appeared to be unfired. I took it apart and the first thing I noticed was the shorter tang on the back of the grip frame. It is an IB date code and the color on the grip frame matches the blue grey factory finish of the receiver and stock backplate. Perhaps someone carelessly used a Hk93/94 grip frame at the factory?

The two pushpins are probably due to the increased recoil of the .308.

There is an 0-1-20 and SEF version for the G3 available for sale by a member in the EE board here if you want to see their differences: http://hkpro.com/forum/showthread.php?t=72209

Numrich has some for sale here: http://www.e-gunparts.com/DisplayAd.asp?chrProductSKU=985050&chrSuperSKU=&MC=

RTG also has some here: http://www.robertrtg.com/g3sefplastic.html

The rear of the G3 receiver is beefed up with the two push pin design to distribute the stress it and the buttstock receive when the carrier violently slams into the buffer.

MP5/33 grip frame on my G3K clone...

I too am trying to understand this and was wondering if it is a drop in install or would you have to modify. My confusion I guess is the two lower holes in the front that look as though they are for a forward push pin. My metal lower does not have both the round holes at the bottom ot that tang up top, it is all flush. Does the receiver have to be drilled for a forward push pin?

Edit: I think I just found the answer to my question. Turbo_supra is your SEF lower modified like this?

Yes. What you are looking at is the ever-popular "clipped and pinned" modification.

I have both lowers. The "0-1-20" is the proper lower for a G3K. Here is a picture of both of mine for comparison:
