Hi all, does anyone know a gunsmith who is able to cut clip slots in the bridge on a Remington 700 receiver?

That looks like an expensive job .
And I suspect reproofing will be involved .
So is it really required ?

200 dollars sounds like a good price to me for that amount of work. Whats the advantage of that type of modification.

Would that not weaken the action considerably?????

It does not impact the pressure-bearing areas (lugs, chamber etc.) and was a standard feature on older 700s and M40X rifles.
The clip slot serves 2 purposes - one is to enable the use of chargers/clips to load the magazine for rapid fire target matches (if the slots are cut with the charger grooves, much like on the charger bridge of a Lee Enfield, K98 etc.) and the second reason, which is the reason I need it done, is for the mounting of certain scope bases. With the need for charger loading removed, the USMC simply cut rectangular slots for mounting the scope bases.
I have a Unertl scope mount and am building a M40A1 clone/replica, so need the clip slots cut to mount the base on the receiver. These bases are made with lugs that slot into the clip slots, mechanically mating them to the receiver.
I need to do some research but it may well require proofing again, as it is altering a component part, albeit not in a pressure-sensitive area.

Will do. I fear this is something I may be doing myself with a dremel

I think you can buy a couple of thousand grinding pads off the net

Hacksaw, files and a dremel to polish. What could possibly go wrong
