Another vote for the 3 port. Have run those on a couple of GMR15's and my JP5 (Steel Challenge Model). The vertical port comp looks like it would be a lot harder to clean out.

I tested the JP pins in the SD3G before i installed it and they fit perfectly. I just left in the J-hook and it works fine. I do like the trigger better than the JP. Seems like its about a pound lighter. I put a Radian 45 degree safety in mine and it works great.

I just ended up using the JP pins with the SD3G. No problems, works great.

The "head" on those KNS anti-walk pins won't fit in the small pin area on the JP5 right hand side near the mag release. Looks like you could prob file on the outside of the "head" to make it fit? Or can you just use the JP anti-walk pins?

Can you use the pins that come with the SD3G (in the JP5), or do you need some sort of anti-walk pins?

Any idea if add-on GMR-15 magwell funnels (TF, etc.) will fit the JP5?
