Here's my old "Semi-Scout" practical-shooting rifle, finally in its new stock after having waited 12 years in our basement in pieces. It's a M1903 action from the mid-1930s, with a 1943 barrel, Lyman and Burris sights, and a 10-round magazine.
(The AP rounds are collectors' items from WW2.)

It'll hold about a minute-of-angle from the bench, which is far better than I can do in the field. That bipod helps a lot, of course. It's an important feature of this new stock. (Previously, I used a Colt's "clothespin," hung on a separate boss built-onto the fore-end.)
Here's the bipod completely stowed away, becoming the stock's fore-end tip!
Neat, huh?

Here's a close-up of its nice old Lyman #48 receiver sight that I found at a Los Angeles County gun show...in parts, at two different tables!
Here, too, is the 10-round magazine box I designed. A gunsmith friend cobbled two Springfield '03A3 magazine boxes together, and added a floorplate hinge and a strong latch. I adapted a BAR-magazine spring to an existing '03A3 follower.
Using files and stones, I gave the rifle a three-pound, single-stage trigger. I couldn't get rid of about 1/8" of pre-letoff creep without compromising safety.

Pachmayr used to make and sell this neat removable butt-pad assembly. It attaches with an interrupted-dovetail sort of arrangement, and it is held in place by a very strong latch.
I added Fiberglas tubes, both as stock stiffeners and as a place to stow a cleaning rod, tools, and spare parts. One of the tools is a wrench for the scope mounts.

Having descended into my dotage in the intervening years, the new stock was assembled to the old rifle by a nice young man, James Reid, here on the island, who has just graduated from gunsmithing school. He did a lovely job!
One funny thing: The original wooden stock I made for it, almost 30 years ago, is a pound-and-a-half lighter than this new plastic one is!
Now I have to take the outfit to the mainland, where I can sight it in at 300 yards. I'll have to calculate sight corrections for greater distances. I miss our 1,050-yard, Southern California range! (We have a scant 100 yards, here on the island.)
(That neat stock was made by Brent Clifton, of Clifton Arms, Grand Prairie, Texas.)
