DELTAC® Slingshot Muzzle Brake for AK-47 - Complete threading kit


New product


More info

We believe that threading the barrel of the AK47 is the most effective method to install a muzzle brake. Threading your barrel with the use of the enclosed threading tool insure your thread are true and are permanent but ensure reliability and accuracy. We also suggest this to be done by a gunsmith.

Thread alignment tool:
This is a simple TAT (thread alignment tool) for re-threading 7.62 caliber muzzles to accept the above M14 X 1 LH muzzle device. 
Made of Stainless Steel 303. It helps you get the die started level and on-center to prevent costly mistakes.

This a heavy duty #5 die handle is approx. 11.5in long and accepts 1.5in dia (38mm) dies like the M14X1 LH die that we offer on this site.  The handle ends are removable. These are high quality handles made of high tensile steel.

PKG Content:

  • 1 Threaded muzzle break
  • 1 adjustable M14X1 LH Die
  • 1 Thread alignment tool 
  • #5 die handle
  • 1 Jam nut

Muzzle Threading Instructions
Screw the TAT about 4-5 threads into the back of the die with the pilot
sticking out in front.
Insert die and TAT into handle, preferably lettered towards you and aligning
at least one of the tightening screws in the handle with the divots in the die
Secure the barrel vertically in a padded vise
Apply a good cutting fluid/oil to the die teeth and start cutting. It will take a
little bit of vertical downward pressure to get started. Apply even downward
pressure and rotate the die slowly.
Repeatedly advance the die about 1/8 turn, then back it off to break up the
shaving (chips).
Do not allow the face of the TAT to ever reach the barrel face. This could
strip the teeth out, possibly damaging the TAT and ruining the few threads
that you have cut on the
Once you’ve cut about 4-5 threads, and before the TAT reaches the barrel
face, unscrew the die completely, loosen the 2 tightening screws on the die
holder, and remove the TAT.
With the TAT removed, put the die back in the handle and hand tighten the 2
tightening screws.
Resume threading as above, breaking the chips and applying cutting fluid as
you go.
Thread to the desired depth, blow off the threads and check the fit with
whatever muzzle device you plan to use. You want the threads firm but able
to screw on by hand.
If your threads are too large, tighten the 2 screws in the handle a little bit,
apply more cutting fluid and run over the threads again. Blow off the threads
and check the fit again. Repeat as needed.
If necessary, you can take the die out of the handle, unscrew the preset screw
in the die itself, and place back in handle, tightening the 2 screws for an even
smaller thread.
Hopefully this information will help you successfully complete your barrel
threading project. Make sure to wear protective glasses throughout the
process and Take Your Time!. This type of work can be very rewarding
when all goes smooth, or a disastrous, aggravating, mess if you try to rush.
NOTE: This device should be installed by a competent gunsmith to ensure concentricity and clearance at exit hole.

Threading my SKS

The crush washer was NOT included in the packaging I received. Considering I've never threaded a barrel before, I found the product easy to use. I watched the tutorial all seemed so simple... I learned that I had to reduce the barrel circumference after a few threads since it tapered out at that point...when I did that it was good....Thanks for the great customer service emails and followup regarding shipping and my satisfaction...

Shop owner reply (Apr 14, 2017):
Thank you for your review. A crush washer is not part of this kit and was never listed as part of the kit because this kit contains a jam nut instead that can be used over and over again
