I didn't know there were different brand of rail pieces so I would have no idea about which brand to choose.

In terms of using the IWC insertion tool, is there any brand that is more compatible than another?

LOL.....no problem, it's been a long day for me as well.

I do not think anyone out there that makes accessory rails for this type of installation, uses an insertion tool such as IWC.

The instructions for the JP rail kind of leave it up to the installer to find something suitable to hold things in place during install......http://www.jprifles.com/instructions/Rifle/JPTR.pdf
