TL/DR = use a DFAT to install your scope reticle plumb with gravity.

If you’re interested in a method that makes installing a rifle scope easy and accurate, read on. Everyone setting up a precision rifle should be insuring their scope is installed centered over the bore and that the scope reticle is plumb with gravity. I’ve discovered an easy new way to install scope reticle plumb with gravity by using a product from DST Precision called the “DFAT”.
DFAT is the acronym for Dry Fire Adaptor Training. The DFAT device attaches to the objective end of a rifle scope. The Lense in the DFAT is designed to focus a scope at 11’-15’. With a scope focused at such short ranges, the DFAT allows shooters to dry practice at very short distances such as a backyard, garage, or interior room.
The same close range focus that allows for dry practice also allows to focus on a plumb line hung across a room.
Here’s the setup. I place the rifle level in a vise and point it at a plumb line I’ve actually drawn on my wall. I then place the DFAT on the objective end of the scope. Next, with the scope rings tight on the base, and the scope loose in the rings, I simply peer through the scope and rotate it until the reticle is perfectly parallel to the plumb line. All that is left is to evenly and alternately torque the ring screws so that the scope is not rotated while the screws are tightened.
Using the DFAT has proven to be much easier than other methods I’ve used in the past. I no longer have to set up a distant plumb line in my yard each time I’m installing a scope. Using the DFAT has also proven much easier than the method of shining a flashlight in the objective lens to project the reticle image on a wall.
I’m not affiliated with DST precision. I’m posting here as well as other places because the DFAT is valuable as a stand alone dry practice tool. Now that we know it can be used for fast and accurate scope setup, it’s value increases tremendously.

DFAT is well known around here. i use one for dry fire

you could also use the butt stock against the wall and hang a plumb line and shine a flash light through the OBJ lens and it casts a shadow of the reticle on the wall. same concept but free.

I read ya bud. I even mentioned that way in my post. Just another way to skin the cat.
 
Good advice...!

Anyone know where I can get a DFAT GEN II for my ATACR 7-35...?
Seems they've been out of stock for some time now...

I’d shoot him an email, he was really responsive when I reached out earlier this year.

Excellent piece of equipment. I’ve owned both gens and glad I got em.

Cool.
Thanks guys.
I've been in touch with Troy & he's right on it as you both said.
A pleasure to deal with - my order will be going in shortly!!
Only the GEN I in stock, but I'm guessing the functionality is the same as the GEN II?

Yea the only difference is that the Gen 1 is a scope cap that is essentially a butler creek with the parts inside of it and the gen 2 is a threaded piece of aluminum (think necked down sunshade) that screws in.

No issues with either. I had the Gen 1 on a MK12 when I was overseas and used it to dryfire daily. I have the Gen 2 for my ATACR at home and there’s no difference. Both are great and you’ll be happy with either.

Smart purchase man, enjoy!
