Remington 6 Digit Actions - Sear ?

[GregV]

I have two 6 digit Remington 700 receivers, a 266,xxx and a 321,xxx, which I am planning on using for an M40 and an M40A1 build. Both trigger assemblies appear to be identical, except for the sears.

The 266, which is an ADL, has a two pieice sear and the 321, which is a BDL, has a one piece sear. I hope I am describing them correctly. Anthow, did the sear type change between Feb. and Dec. of 1967, or is it just possible that the later one was changed out at one time? I am using the date codes that were on the barrels of each rifle when I got them. I am thinking that the barrels were original to the receivers, but I don't know for sure.

Thanks, Greg V

My 351xxx short action is a little later than either of yours' but it has the one-piece sear, if that helps.

Thanks. It sounds like they may have changed sometime in 1967.
