​Dryfire, Focus, Adapter, Training

The D.F.A.T is a DST Precision Product, that we're happy to carry, as a top notch training tool.

This device allows you to use the rifle and optic to dryfire practice in a very small area.  With this adapter most scopes focus in the 11-15 feet range, depth of field is about 6”.  By increasing your parallax distance you can sometimes increase that focal distance.  With proper lighting you can use your scope at maximum magnification.  Perfect for in the house, in the garage or a small backyard.  Use this device to practice different positions, balance points on the rifle, slung vs unslung, various support bag combinations. I have found the D.F.A.T to be extremely valuable in determining how small I can make my "wobble" with non-prone positions.  Usually shooters can get a good idea of their abilities and improvements by dry firing on known "MOA" size targets. 

37 D.F.A.T.- HD   ->Most Universal Size
The 37 D.F.A.T.-HD  has the aperture lens system held within a threaded aluminum sunshade, like other Gen 2 D.F.A.T.’s, It is different than the 55,58,62mm DFAT’s in the fact the glass lens is held in with a threaded retainer. It is possible to remove for cleaning if needed.  This design provides a very secure fitment like lenses in a scope.     

Another advantage of the 37mm Gen 2, is the smaller diameter allows one DFAT to fit more scopes without any barrel clearance issues. In the past we needed additional clearance  since the outside diameter could be larger than the scope you were using it on, examples 62 D.F.A.T.  O.D. 69.5mm, 58 D.F.A.T. O.D. 64.5mm, 55 D.F.A.T. O.D. 60.5mm. 
Currently we have adapter rings to allow the NEW 37 D.F.A.T. to fit the following:
27mm = M27 x 0.75
M47.25 x 0.6 
55mm (D) You can then use the other 55 adapter rings above 55 to make a 55mm or larger scope ring fit the 37 D.F.A.T with this 55mm ring as an adapter.

​55 D.F.A.T to: (56,57,57.5,58,59,60,671D,62,63, VX50, VX56)  


any "to 55mm" D.F.A.T. ring will fit the 55 D.F.A.T

any "to 37mm" D.F.A.T ring will fit the 37 D.F.A.T

and any "to 55mm" D.F.A.T. ring will fit the 37 D.F.A.T. with the addition of the "55mm to 37mm" adapter ring in addition to the ring size you need or your scope.

For example, if you have a 37 D.F.A.T that you usually use on your Leupold Mark 4 LR/T 3.5-10x40 with a VX-40mm to 37mm DFAT Ring, and you want to also be able to use your 37 D.F.A.T. on your Mark 5HD 7-35x56 you'd need to purchase the ring for that scope (the VX-56mm to 55mm ring), as well as the 55mm to 37mm adapter ring to make the VX-56 ring be able to adapt to the 37 D.F.A.T.

55 D.F.A.T.-HD fits: (Larger than scope bell, ensure enough clearance 60.5mm)
55mm fits: Vortex PST Gen 2 5-25x50, Vortex 15-60x52 Golden Eagle, Vortex 3-9x50 Crossfire, Vortex 4-24x50 Strike Eagle, Vortex 3.5-10x50 Diamondback, Athlon Argos GEN 1 

37 D.F.A.T.-HD fits: ALL adapter ring combination/available will work with this size
37mm fits: Vortex 2-8x32 Diamondback HP, Vortex 1.75-5 Diamondback, Vortex 2-10x32 Viper PST Gen 2, Vortex 2-7x32 Crossfire I.

But more IMPORTANTLY it allows use of all the adapter rings available

37 DFAT-HD with thread adapter works with scope bells very close to barrel.
These are not scope OD this is the inside thread diameter of your scope/sunshade attachment. Consult your scope manufacture for your scope thread pitch/diameter.)

Please see THIS PDF for further size Information on ring sizes for different scopes.

In the drop down menu when selecting your size DFAT adapter ring to be able to attach your DFAT to your scope, there is the option to purchse the DFAT without a ring incase you need a reaplcement DFAT but still/already have the proper rings, however if you're purchasing a DFAT for the first time, you will need the appropriate ring to attach/use it on your scope.

THIS PDF has additional information and recommendations from Troy - creator of the DFAT.

The D.F.A.T. is great for helping you to find and build stable positions when shooting from a variety of positions.  
Take it one step further!  By picking random shooting environmental data you can get even more out of your practice.

889 yards
12 MPH wind from 3:00
DA= 3000 
Start port arms 60 seconds to get into position and 5 shots off.

I guarantee your 4th time doing that will be way faster than your first.  If you shoot in matches, or practice for hunting this will improve your confidence and speed.  
How comfortable are you with your Ballistics app?  Better to practice now than when you are under pressure.


The Gen 2 version of the DFAT has the aperture lens system held within a threaded aluminum sunshade. This is a very precision fit and be careful. You DO NOT want to cross thread your scope or the adapter.
