How to check your scope rails…
So….
The trirail from AF is about 1/64″ off center and the single piece mount for my scope from accushot was about 1/32″ off center, add these up and suddenly the scope is far left of the centerline of the rifle…

Who the hell designs these things and do they know ANYTHING about how it works?!?!!?!?!? WTF!!!!!
Fine if your only shooting at 35 yards any thing closer will hit to the left of the centerline of the crosshairs any thing further it will hit to the right.
Goto shoot a FT setup at various distances and everything is fucked no matter where you setup the scope…
SO I made a funky little gauge from a leftover part for the silent pellet trap. I bought a breaker panel for the outside box, it was cheaper then the outdoor ones. And it had a little spot inside (that I removed) for the wires to attach to the panel.
Well each hole is threaded for screws to retain the wire and with a few longer screws I was able to make a gauge to check the center the scope on the frame of the rifle.
Mine was about 0.03″ too far to the left off center, I used the gauge to determine how far it was off from one side and divided it by two and reused the gauge to check alignment after shimming. I used a thin piece of pvc sheet to shim, should work well…
Here are a few photos.
First one shows the part with screws to check alignment.
The second shot shows the shim…

My tri-rail was received in June of 06. I’ve no idea when it was manufactured. I’ve had no such problems with mine. It squared up nicely. Sorry for your misforture. AKULA
Nice work. I’ve suspected a misalignment based on a left / right POI shift vs distance. I may try that gage trick.
Thanks for the post, I think that pretty slick, I think I need to make one to.

I have had two bad tri rails. With the first one, I could see that the scope was not parallel to the center line of gun. The second one was not much better but I have shimmed the mounts on the rail–I will try shmming the rail as well. I was told this was not a problem, but in reading these posts I can see this is a bigger problem which has not been addressed in the production of the tri rail.
