Hey Everyone,

I ended up getting a Vortex PST 1-4 with a AD Recon QD mount. Just wondering if someone can help me with the below.

1) When mounting the QD mount do I push it towards the barrel or to the butt?
2) Do I torque to the scope specs or to the mounts specs?
3) What is the best way to find eye relief? Is there technique?
4) I have a laser bore sighter is there a way of getting it close before going to the range?

Thanks T
 
1) Towards the front of the gun
2) Scope torque specs
3) Mount scope but don't torque it down, get behind rifle in shooting position with eyes closed, open your eyes and see where the eye relief needs to be, adjust scope, repeat until you get it where you like it.
4) Can't help you here. I've never used a laser bore sighter. I just take my rifle to range after mounting the scope. Shoot paper at 25 or 50 yards and get it close. Then go out to 100 and sight in.
 
I am no expert but here's my take.

1. Not sure what you mean. I assume the levers? They should fold forward to the barrel.

2. Torque to the mount specs but don't exceed scope specs. Normally a scope can take more pressure than the threads of the scope mount can: aluminum and/or fine threads can strip easily.

3. As Clocked92 said is good: leave everything just tight enough to hold and adjust as needed. I never set a scope so that it is "tight to a bell" (where the ring is very close to the eye piece, center and/or objective) because you want to be on the center tube surface that is exactly the same diameter inside the rings everywhere (if that makes sense - not sure how else to describe without taking forever).

4. I use a 1/4" grid target or make one. Figure out the distance from your bore center to scope center. At 10 feet make sure the cross hairs on the 1/4" grid and the laser point are the exact same distance vertically apart (up & down) as your bore to scope centers. At any distance, until you sight in with ammo, the cross hairs and laser point should be exactly vertical (hairs above pointer).

You are looking for the center one where the perfect vertical height from scope cross hairs to bore is the same on the gun as at 10 feet.

There are other ways, likely better ways, but this method gets me on paper at 50 yards every time on the first shot, then two more at 100 yards and I am ready to super fine tune. I have done firearms this way and I am usually a tiny bit low but centered at 100 yards in the first shot.
 
For #1 I guess I should have asked exactly what you meant. I'm assuming that you are talking about the entire mount on a pic rail? If so, push the mount forward so it is touching the rail. That way, recoil should not affect the mount.

and yes...for #2, tighten to mount specs but don't exceed scope torque specs. I know that some mount specs like nightforce ask for 25 in/lbs but my Vortex AMG says only 18 in/lbs. Definitely don't exceed the scope specs or you risk damaging the tube.
