Impact 737r bolt diameter?

[ormandj]

I'm trying to order a bore guide for my incoming 737r, but I need the bolt diameter. Does anybody happen to know it or is willing to measure it for me? I'd much appreciate it. I wasn't sure if it was the standard R700 0.700" +-0.005 or something else. Thank you!

I just measured mine at .700+/- for the bolt body diameter.

I thought the caliber was enough to know.

You need the bolt diameter, since that's where the bore guide sits and must be centered, as would be the bolt. The caliber is important as the guide does slide up into the chamber, and obviously must be large enough to pass the cleaning instruments. The rod must fit through, so you need to know the diameter of the cleaning rod in order to ensure it's properly centered as well.

I use the PMA Remington/Panda 6br bore guide in my Impact action and it fits perfect. Just choose the right caliber for your rifle.

6.5mm CM version from PMA tool is what I purchased. It fits like a glove, and is a perfect fit on my ProShot cleaning rod with the insert.
