Are the FN SPR enthusiasts extinct?

FN SPR A5M XP 24" barrel
TBM Kit
Surefire SOCOM 7.62 Brake
Leupold Mark 5 5-25x56 scope with CCH reticle
Leupold Mark 4 Scope Rings
Flatline OPS Bubble Level
Harris 6-9 BRMS with KMW Pod Lock
Easily one of my most favourite rifles but I found it to be very picky with Projectiles.
All ELDM's shoot really well out of it but Berger and Optimus bullets didn't.
It has a long throat which doesn't help but I have it sorted now and it's a hammer.
Settled on 168gr ELD-Ms at 2730fps. I've had it to 800m but no further.
Only dramas I have with it are the FN Mags.
The rounds are "loose" in the magazine compared to Tikka and AI mags - this means they rattle and can actually shift in the mags which can cause feeding issues. Other than that, to me this is pretty much the perfect precision rifle.

Anybody know which of these two bottom metals works with AICS style mags?



The first one linked above has a disclaimer at the bottom saying it comes with one of their mags and only that mag works. Any other AI mag will not work. That is kinda weird.

The second one doesn't mention any of that.

I know some of you guys here run a PTG bottom metal with AICS mags. Can you guys check which one it more closely resembles?

Thanks
 
Anyone on here try out the ops2 titanium skeletonized rail? I’ve had a problem with rings clamping on my factory fn rail so I tried the ops2 rail and it’s doing the same thing. The rings I’m using are vortex branded seekins precision 34mm. I’ve tried 2 different sets on 2 different optics that work perfectly on my impact and r700’s. Bothe sets I’ve had for several years and know the rings are good. Is it possible the ops2 rail I got is bad? Thanks

It’s probably the rings

I torqued the rings at 25 inch pounds and I can see the rail moving sideways maybe .02 to .03. I currently have a g2 viper in a set of 30mm vortex pmr rings and they clamp fine. Rifle shoots .3 to .4 moa with that setup all day. I also have a set of Warne mountain tech ultralight ring I tried and they will not tighten enough either. 2 sets of the cheap vortex pro series rings work fine. It’s weird.

What do you mean the rail moves? Is it compressing, or is it not tightened to the action?

I’ve measured the factory rail and it is good according to the milspec blueprint someone on here sent me. I thought maybe I missed something. That’s why I ordered the ops2 rail and it’s doing the same thing.

Measure the inside of the ring attachment when rings fully tightened.
 
I’m 99% sure it’s the rails. Of that I have no doubt. The only dimension I can’t measure is the thickness of the rail on the 45 degree flats. I’m thinking they are too thin on both rails. Either way the rifle is a shooter. I’ll just be very limited on what rings I can use on it. Really disappointing in a 2000$ rifle.
 
Just reading this is making me feel stupid. I’m sorry bro but I’m shocked at how hard this seems to be for you to figure out. Also shocked at the fact your getting help at what seems to be your complete dysfunction.

The dimension circled in red is what I was talking about in reference to the 45 degree flats. I don’t know how to check that dimension so I can’t confirm it is within spec on the factory rail or the ops2 I ordered.
 
Process of deduction. You measured the rail and its within spec. The rings don't fit tight on said rail. Leaving the 2 options of a) the rings are out of spec or 2- you didn't measure correctly. It's the only 2 options.
My assumption is I have either 2 sets of vortex precision rings that are bad. Or 2 picatinny rails that are bad. Both sets of rings work on every other rifle I own. So logic says the rails are bad. So back to my original question that I may not have asked clearly.

Has anyone else got a bad ops2 rail???
 
Then it's something with the rings unless 2 separate companies manufactured the rails with the wrong angle. If the thickness of the rail is right, the width is right and the height is right. The number you can't check becomes irrelevant. It has to be right.
 
I would assume that. But if both rails are in spec then I have 2 sets are vortex precision rings and a set of warne mountain tech ultralight rings that are out of spec that just happen to work on every other rail I have.
 
If your rings work on all your other rails, buy a replacement rail for your SPR. Turn the questionable ''out of spec" rail into an expensive paper weight, coffee table center piece, or the likes. Write it off as lesson learned.
 
I agree. Plus knowing the way rings work (along with the fact that you're using rings that are typically pretty solid) makes me think rail. I would guess that most ring designs allow for some variation in rail dimensions as you tighten that 'clamp'.
 
The 306-06SPR is still an active item at Badger Ordnance.

They just haven’t had any available for some time.

I know they are dealing with high demand and production challenges just like other manufacturers in the firearms industry.
