700 Police Scope Base Screws 06-48 or 08-40?

[astrohound24]

I picked up a Remington 700 Police .308 a couple days ago. Looking forward to getting everything together and shooting. I have seen some information online at various places that says the Police versions of the 700s are now drilled and tapped for 08-40 screws from the factory instead of 06-48. I have contacted Remington but have not heard back. I figure someone here will know for sure, but apparently some have ran into this. One source said he contacted Remington and one individual there didn’t know, and one said yes all police versions are 08-40 now. I am looking for a scope base and 30mm rings also. Seekins, etc. Anyways I just want to make sure I order the correct scope base with the correct screw size. If I can’t verify I guess I can try to measure the screws. I would feel better to have confirmation from some of you because I know you guys will know. I am open to suggestions also on a scope base and rings, bipod, etc. Thanks for your time.

I measured the diameter of one of the holes and it was nearly 5/32 across so I guess that translates to a number 8 screw but if anyone can verify what they know about it I appreciate it. Thanks.

You might try pulling a screw from one of your other rifles and see if it fits.

Most likely 6-48 if your rifle is a few years old.

The 8-40 thing is relatively new for the 700P's.

You could buy a Leupold Mark 4 base as it comes with both sized screws and the base will work with either size.

I just picked up a 700P in the last couple weeks and they are 8-40

The label on the box will actually show the 8-40 designation on most of the Police models.

If yours is the 8-40 version, you can get the base already factory setup with the 8-40 screws and appropriate counter sinks.

Well that settles it. Thanks for the info everyone. It ended up being #6 screws. I know this might be a deep hole question, but should I get it tapped out to the 8s or just not mess it. Thanks again for help.

I wouldn't bother having them tapped. Ive never had issue with my #6s

10-4. I will just leave them. Thanks!

Years ago I made a spread sheet to compare linear length of screw size & threads-per-inch to better understand any difference
choices make in length of fastener thread engagements. You can see from the chart a 6-48 screw actually has a tiny bit more engagement
length than a 8-40, not significant but the smaller screw is a comparable choice.

In my mind this has needed to happen for awhile. 6-48 is proprietary to the gun industry. Going to 8-40 just makes sense from a standards perspective. There's no real good reason to use the odd ball thread size. Kind of like 1/2-28 for muzzle threads in the US, and 1/2-20 in Europe...no real reason except to make it more difficult for the end user to source their own parts and tooling.
