Welcome to Tune Pro X Precision Barrel Tuners & Front Rest Rider Plates

About Us

We are based in the United Kingdom and specialise in producing precision products to enhance the accuracy of rimfire competition rifles.

At present we are focused on barrel tuners for rimfire rifles - however our research is ongoing and we will in the near future present products for centre fire rifles and other related bench rest and prone shooting accessories - please see our products available section for our latest Front Bag Rider plates to fit a variety of shooting platforms - as our products are fully custom built to your needs please contact us to order at tuneprox@gmail.com

We specialise in Anschutz, Lilja and CZ barrels for off the shelf units but also do custom units for BSA tapered barrels - that is not the limit though - if it has a barrel a plan can be made.

Adjust your barrel harmonics to suit your ammunition choice with any of our barrel tuner models and negate the issue of ammunition batch variants - simply choose your brand and tune your barrel to suit each batch.

Development of the Tune Pro X Products

Background

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 different weight and shooting classes

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.

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.

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.

Sizes offered as standard:

Our aim is to produce the most snug fitting over the barrel tuner body as possible as a poor fit would be aesthetically unpleasing - we offer standard sizes that suits the most popular Anschutz 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:

Please see the detailed instructions below this section.

Models Offered:

A1 and A2

Frequently Asked Questions:

Please contact us at Tuneprox@gmail.com if you cannot find an answer to your question.

1.Do they work?

YES they do reduce group sizes dramatically.

We base that statement on the real world feedback from all our clients and our own range results and not lab produced figures.

Every single client that has fitted one has reported much reduced group sizes and less vertical dispersion.

In our own club users of the Tune Pro X has moved up several divisions and their scores have improved.

Every single user in other clubs have shown increased scores and personal best scores - to date not a single tuner user have returned with a negative verdict or review since using our product.

Since using Tune Pro X tuners ourselves in competition we have won the prestigious Yorkshire league hosted in the United Kingdom centenary competition in all 3 sections in the top division 1 - this is the 6 top competitors in the country in 20m,50m and 100yds 2024.

Competitors in this competition include European and world championship competitors and International shooting competitors that represent the country.

We have won the winter Perthsire league in Scotland 2025 with a record score of 1998 out of a possible 2000 points in division one.

Feedback from clients have a reduction in group sizes of 15 to 30% minimum and our own results mirrors that.

2.How does the tuner attach to the barrel and do you need special tools and is any gunsmith work required?

The tuners are custom made to your barrel profile and is a very snug slip on fit generally made 0.05mm / 0.002" larger than your barrel for perfect fit.

2 Allen bolts tightened with Allen key is all required to clamp it in place and you are set - no gunsmith or threading of barrel required - the tuner is generally fitted flush with the muzzle or if the barrel is threaded right behind the thread cap , muzzle break or moderator.

Adjustment of the tuner once fitted is tool less and done by hand - the adjustments are infinitely fine in increments and you can adjust repeatedly in increments of 0.001" at a time if required it could not be simpler - no grub screws no ratchets and it does not rotate unless turned - the patented friction system is totally effective.

3.Does it extend the barrel and how do you avoid carbon build up and how do you maintain it.

It does not extend the barrel as it is mounted flush with the end of the barrel unless the owner decides that for barrel profile reasons it would be the better option to mount it overhanging the muzzle - we have had to do that in a couple of cases where an unusually large increase in profile was out of the design spec of the tuner - there was absolutely no detrimental effect on the function of the tuner as long as the 30mm length of the clamp was fully engaged on the barrel.

As our tuners are the outer diameter of the barrel and the overhang would be maximum 40mm it is still relatively easy to clean the muzzle and inside of the tuner without removing it.

The result of normally not extending the barrel and mounting it flush negates the removal of the tuner for travel or having issues fitting into gun cabinets or rifle cases.

There is no carbon build up as free access is available to the muzzle for cleaning and maintenance - the tuner is virtually a sealed unit and maintenance free - not requiring the removal of the tuner negates re-tuning on removal and replacement of the tuner as .001" linear movement can make a huge change. Removal and replacement of tuners can have detrimental effect on your tune if the tuner is not replaced in exactly the same position - with a difference in position of 0.001" causing significant changes this is a huge advantage.

Less or more torque when replacing a screwed on tuner can also have a detrimental effect so we avoided that in the Tune Pro X design.

4.Do you ship to Countries outside of the UK?

Yes we do and welcome overseas customers - contact us direct at tuneprox@gmail.com for assistance.

HOW TO MEASURE YOUR BARREL FOR PERFECT FIT

Accurate measurements is essential

Please measure your barrel in the area where you want the tuner to be located - the Tuner is 70mm long and is normally fitted flush with the front of the muzzle or if barrel is threaded flush with wihere the treading end to allow muzzle break or moderator to be fitted.

The tuners are made 0.05mm larger than your barrel so please measure as accurately as possible with a vernier

Measure your barrel vertically and horizontally

Often barrels are slightly out of round in dovetail areas - please measure in the vertical and horizontally in the 0,35and 70mm locations we need these measurements to ensure that we cater for the largest area in your barrel

Not enough space?

Should you have flutes on your barrel or the bulbous section or smooth section as on the Walther KK 500 barrels is shorter than 70mm this is no issue the tuner clamp is only 25mm long and a overhang over the muzzle is possible without affecting tuning
