I’ve had a couple SPR’s (308 & 300wsm) and now have a Stealth. I can tell you the barrel contour is extremely close. I measured it but didn’t write it down so I don’t have the exact measurement. IIRC, it was within .03” at the 24” mark of the SPR’s 24”muzzle and the shank was the same size of the SPR. No chrome lining in the stealth as mentioned above. It has standard size scope base holes, not the heavy duty screws of the FN nor does it come with a high quality base like the SPR does.
When I dropped my action in a takeoff McMillan A1 I had bedded for the SPR I had to open up the inlet slightly after removing the bedding. The channel from the mag area back to the action screw was just narrow enough not to fully seat. The recoil lug was also a touch wider in both directions. The stealth has a MOA Winchester trigger rather than the two lever of the SPR.
Both types of triggers can be tuned if you don’t like how they come from the factory, however, the MOA does need a spring to be replaced and I found a good source if you are so inclined.
That and the truing mentioned above (which I didn’t know about at the time I owned the SPR’s) is the major differences.
Now for the little things.
Because I reload I can also say that the chamber on my Stealth is also different. The free bore is much shorter and the chamber case dimensions also appear to be tighter. Don’t miss read that, the SPR was not Remington sloppy by any means. It’s almost like the Stealth has a minimum spec chamber as my brass requires very little sizing. 175 smk’s run into the lands of my Stealth at around 2.785” COAL where the SPR, IIRC was a good .050 longer or more... I got rid of my SPR measurements when I sold the rifle.
Performance differences...
The 26” Stealth is a good 75-90fps faster than the 24” SPR was.
My best loads in the SPR after I bedded it would run in the .4-.6’s at 100 yards for five and before bedding, was a .7 of an inch. The Stealth is by far the most accurate factory rifle I have had the pleasure of owning. Mind you it’s been restocked and bedded now... so I guess it’s not necessarily a spec factory rifle anymore. But it has now shot several groups in the .2-.3’s during load testing.
The last time I was at my 1000 yard range I was doing a drill where I would get out of position for every shot and it just hammered the 800 yard steel target, 15 shots all inside of .25 milrad on my FFP reticle and here’s the kicker, I was using pulled (de-milled) 175’s, some of which I know to be out of round. To say I am pleased with the Stealth would be putting it mildly. Fast and accurate, I am going to be holding on to this rifle. And to think I was considering cutting the barrel down but decided I should shoot it first, glad I did...
I picked up my Stealth used a couple years back and it looked unfired. The clerk told me the previous owner had won it at a local gun club and didn’t like it. If I was a betting man, I’d bet he didn’t like the chamber as I could see it causing a problem with standard grade factory ammo... I know FGMM ammo will be jamming into the lands a little.
