Yes, the Rem 700 FS featured a stock made by Brown Precision.
They were offered either in a solid grey color or a camo painted pattern.
They were made 1987 to 1989
Here's some info from an earlier thread
https://www.24hourcampfire.com/ubbt...s/5756025/Re_Remington_700_FS_fiberglassThe FS stock was made by Brown Precision and is a proprietary design especially for Remington. The pistol grip is the same long open style of their standard model but the forend is much more slender. I've had two, a 7mm Rem. Mag and my current one, a .30-06, both left hand. Some were made with a nice ghost leaf pattern and some were plain grey. FWIW Brown will still make this stock pattern as they still have the mold, or had when I called about 4-5 years ago.
These things were always real sleeper deals. You got an excellent aftermarket stock and barreled action for just a tad more than the going price of a standard Model 700. The recoil lug on the .30-06 is very neatly glass bedded into the stock. All metal is matte finished, including the bolt and the stock is the blind magazine ADL style. The .30-06 with Talley lightweight mounts and a Leupold 4X scope weighs 6 lbs 15 oz. unloaded. Subtract the scope and mounts and the rifle alone will run right about 6 lbs 4 oz. Not bad for a full contour barrel in a long action. A short action .243 will run a couple-three ounces less than that.
