To fit the barrel tuner, your gunsmith will need to modify the front of the rifle barrel and add an M20 x 1.0mm right hand thread in accordance with Dwg No: DGC-BT-01.

DGC barrel tuner fitting

Initial Fitting:

Screw barrel tuner body onto barrel until it stops at rear shoulder. Secure in position with the three Allen screws. Test fire the rifle and verify / record the shot grouping.


Loosen the three Allen screws and adjust the barrel tuner body by un-screwing it away from the shoulder. The markings on the external body can be used for reference. Set the desired position and re-tighten the three Allen screws. Test fire the rifle, verify and record the shot grouping. Repeat the process, as necessary, until you achieve a position with the tightest shot grouping.

Cost Retail is £75.00 Including VAT

NEW Ezell barrel tuners

Ezell PDT Tuners | Centerfire or Rimfire versions now available

Ezell PDT Tuners – Our new barrel tuners.

PDT stands for particle dampening technology. We applied published scientific research on particle dampening technology to our barrel tuner.

The advantages are a wider tune window and less ammo sensitivity due to more efficient control of barrel harmonics…in a tuner design that looks great. This is the next step in the evolution of tuner design and is significantly better than tuning with solid mass alone, as is the case with most other tuner designs currently available.

PDT tuners work equally well on both centerfire and rimfire rifles, and can use your PRX length in most cases! The centerfire tuners are designed to thread onto the barrel. The rimfire version clamps on like a Harrell’s and can be bored to your barrel diameter, and as mentioned, cut to your nearest PRX, if desired.

Call us today to find out more about what is the best tuner on the market.

PDT tuners come with both installation instructions, as well as simple instructions on how to tune your rifle quickly and easily with it.
