Welcome to Tune Pro X Precision Barrel Tuners

Our family have been shooters and reloaders for 40 years and taking part in rimfire competitions have highlighted a common problem with regard to rimfire ammunition - testing of multiple brands from entry level to premium - all have a certain standard of consistency in a lot produced but bullet speed does vary between batches - this puts the competitive shooter in a position where once a batch that really suits their barrel harmonics and produces the desired accuracy becomes unavailable, they then are back to square one looking for a suitable batch from their chosen ammunition brand.

This frustrating situation led to the development of the Tune pro X barrel tuners and the different models cater for optical sighted bench rest type rifles as well as diopter sighted rifles.

The result after prototype development in conjunction with our fantastic engineering team resulted in a tuning system that is simple to fit, a precision high quality instrument that is virtually maintenance free and offers repeatable infinite linear adjustment to tune your barrel to suit your ammunition and atmospheric conditions.

The fact that the tuner requires no alteration of your barrel profile or requires threading of the barrel negates the possibility of affecting your barrel choke at the muzzle end.

The costs and concerns involved having to send your rifle away to have a tuner fitted is negated and not having to concern yourself with batch changes is a game changer.

Furthermore the muzzle of the rifle is accessible for maintenance and cleaning and the system does not extend your barrel and cause issues with rifle cabinets and carry cases.

After extensive testing the use of special low resonating alloys and recoil resistant threads were developed - ensuring minimal vibration and harmonic disturbance of the barrel during the firing process.

Tuner adjustments once fitted is completely tool free ensuring repeatable adjustments by hand making the process ultra simple.

We even cater for tapered barrels as found on the multitude of Martini action BSA rifles used by local UK shooters.

We strive to fit your shooting platform with the most snug fitting over the barrel tuner body as possible as a poor fit would be aesthetically unpleasing - the following  standard sizes that suits the most popular Anshutz and CZ rifle barrel models - these sizes do cover most heavy barrel sizes but should you have a barrel that do not closely resemble these sizes or taper we would gladly assist to get the best fit possible.

Measuring for size:

We do suggest the following to achieve a good fit :

Measure the muzzle end diameter and barrel diameter at 70mm from the muzzel end - the length of the tuner is 70mm - using a accurate digital vernier.

Supply us with your exact measurements - we will add a correction of 0.05mm to allow a good fit.

We do not accept responsibility for incorrect measurements - should the unit be undersized that can be rectified at additional cost of postage and £25 - oversize we cannot do anything about - the clamp can accommodate a 0.5 mm oversize but the fit at muzzle end will not be optimal aesthetically - however the function of the tuner should not be affected.

The following barrel sizes are standard Anschutz and CZ - bespoke sizes will be at a additional charge of £35.

1. 22.00mm - Tuner bore max 22.05mm to fit the barrel snug.
2. 23.90mm - Tuner bore max 23.95mm to fit the barrel snug.
3. 25.56mm - Tuner bore max 25.61mm to fit the barrel snug.

Models Offered:

Model A1 £260

All Brass alloy mounting body and tuner weight no integral dovetail - aimed at bench rest shooters with optical sights that is not concerned about weight and would prefer the additional weight to control recoil and dampen harmonics most effectively.

Total weight 550grams (this varies slightly as tuner bodies are machined to fit individual barrel sizes - the tuner weight remains constant.)

Model A2 £260

Aluminium T6 alloy lightweight body no integral dovetail - aimed at  shooters with optical sights concerned about weight - the tuner weight is the standard weight of all the tuners so the tuning capability of the tuner is not affected

Total weight 340 grams (this varies slightly as tuner bodies are machined to fit individual barrel sizes - the tuner weight remains constant.)

Prices above include postage and secure packaging - postage will be via Royal Mail signed for or by agreed arrangement.

Payments preferred by Bank Transfer or PayPal - once we have clarified your needs and location we will invoice you accordingly.

As we are a small business - orders - particularly custom bespoke sizes will have a 14 + day lead time unless we have your size on the shelf
