D.F.A.T.
Dryfire, Focus, Adapter, Training 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. |

GEN 2 D.F.A.T.- HD 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.
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 31mm 32mm 34mm 40mm 43.5mm 45mm 46mm 46.5mm M47.25 x 0.6 48mm 49mm 52mm 52.5mm 55mm (D) You can then use the other 55 adapter rings. 55 to: (56,57,57.5,58,59,60,671D,62,63, VX50, VX56) ALL GEN 2 DFAT's include the "TARGET PACK #2 " 10 - 7.5"x11" High Resolution range images with a variety of targets printed on heavy paper. 62 D.F.A.T.-HD fits: (Larger your scope bell, ensure enough clearance 69.5mm) 62mm fits: Gen 2 Razor 4.5-27x56, Weaver 6-30x56, Several Nightforce scopes with 56mm objectives including the 5-25x56 ATACR, Athlon Cronus 56mm, Revic 4.5-28X56 58 D.F.A.T.-HD fits: (Larger than scope bell, ensure enough clearance 64.5mm) 58mm fits: Kahles K624i, K1050i FT, K525i, Steiner T5Xi 5-25x56, Steiner P4Xi 4-16x56, Schmidt & Bender 5-25x56 PMII, Minox ZP5 5-25x56 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.

Please refer to the Sizing chart on the HOME PAGE. There is an Excel document that has more size information. |

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.
Imagine:
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.

Below is a video of a spinner being shot at. I used on my phone landscape layout to make the spinner small enough to present a challenge. The best learning you can take from this, can you get your gun cycled, leveled and back on target before you miss the first opportunity to hit the spinner the next swing. If you reload I have loaded 10 dummy rounds, no primer no powder and use them to simulate the added friction when chambering a round.
