HFT 500

THESE WORK OPTIONS ARE FOR NON-REGULATED AIR ARMS ONLY WE DO NOT WORK ON THE REGULATED AIR ARMS RIFLES UNLESS IT HAS BEEN PREVIOUSLY FITTED WITH ONE OF OUR REGULATORS.

APEX Regulator & Tune (Includes a full service)

The APEX Regulator & Tune packages are designed to make your rifle more consistent and air efficient, not more powerful. All sub 12 (non FAC) rifles are set to around 11.5ft/lbs after any work is done, keeping you well within the legal limit.

Features of the APEX Airguns Regulator:

• UK-Made: Designed and manufactured in the UK, home to the most demanding airgun shooters.
• CNC Machined Components: Crafted from premium materials for stable regulator performance.
• More Plenum Space: Greater efficiency with less residual pressure drop on firing.
• High Resolution Pressure Setting: Ensures mechanical stability.
• Easy Reading and Setting: Clear body and adjuster markings.
• Longer Service Intervals: Larger section seals for greater reliability.
• Adjustable Pressure: Ranges from 20-170bar, maintaining pellet speed and accuracy.

When the work is done by the RAT Works the action is extensively worked on to increase the performance, efficiency, accuracy and overall feel of the rifle. Almost every aspect of the rifle is modified, changed or enhanced in some way.

Below is a list of all the work undertaken as part of the tune. Where possible e also engrave the breech block with our small round logo as a way of showing that your rifle has been regulated and tuned by us, this is free of charge.

Hammer Mechanism

- Ensure the assembly is free of any oil, grease or debris which can cause consistency issues

- Re-finish hammer spring to a higher accuracy

- Polish the bearing surfaces in the hammer

- Hammer/trigger sear mating face is modified if needed

- The Hammer spring is considerably shortened to reduce the power after the regulator is fitted, this makes cocking effort much less and puts much less pressure on the trigger sears, allowing a much crisper and responsive second stage.

Loading assembly

- Loading probe modified for pellet feed and smoothness

- Bearing surfaces polished

- If you include the magazine in with your rifle they are also modified to remove any loading issues such as jamming whilst cycling

- Lubricant is added to parts of the assembly to allow a smoother action

- Bolt lock up mechanism is usually modified for more responsive and smoother movement, also increasing the rifles consistency.

Exhaust valve, transfer port & barrel

- The exhaust valve stem assembly is modified to run more efficiently

- Valve body is modified for better airflow through the firing cycle increasing efficiency

- The valve pressure is reset to give a better performance between heavy and lighter pellets

- The transfer port is modified to give a higher degree of air flow efficiency

- Crown of the barrel re-cut or polished if needed to increase the rifles accuracy

- Transfer port and barrel are aligned correctly

- The Adjuster in the transfer port is set with minimum restriction to allow a much more efficient use of air, 90% of the power setting is done with the hammer spring shortening. Only the final setting is done on this adjuster, which also helps with the FPS variance.

Trigger assembly

- Sears are polished to a smoother finish if needed

- Hammer engagement sear modified if needed to smoother let off

- Trigger let-off is set to a comfortable and safe amount.

Some parts may be chargeable although I do replace many damaged parts for free as standard. 

O-ring seals are replaced as standard throughout the rifle and refitted with the correct lubrication.

After the regulator is fitted and the tune carried out you can expect a shot to shot consistency of single figures as soon as the rifle has been worked on. A report sheet will be included with the rifle once work is complete detailing the shot to shot consistency through our SKAN chronograph, the rifle is held correctly in a mount to guarantee accurate results.  This consistency will improve further as the rifle is used.

Service and Upgrade - Previously RAT Works tuned air rifles only

Our service and upgrade package is for air rifles that have previously had the Tench/APEX regulator and tune package. With a service and upgrade we will replace all the orings in the air rifle as well as applying our latest tuning formula and upgraded parts. We will often recommend this if the air rifle in questions hasn't been to us in 12 months or more.

Full Service 

The full service strips and rebuilds your rifle replacing all seals and renewing any worn parts to revamp performance while sorting any problems you may have such as leaks, low power, poor shot count or other faults.

We now replace the firing valve and reface the valve seat as part of the full service. 

PLEASE NOTE: We are not able to work on rifles fitted with aftermarket regulators other than ones we have fitted ourselves.

Important Gauge Information!

Once your rifle has been fitted with a regulator, the original fill gauge will read regulator pressure and not fill pressure. This is due to the location of the regulator and the standard gauge. We will blank your original gauge off with a RAT Works sticker so the gauge is no longer readable.

If you require the ability to read fill pressure from your rifle please select the "Quickfill & Gauge" option below.

Safe practice is to always observe the gauge on your air bottle/dive bottle and ensure that when filling your rifle that the gauge reading does not exceed your rifle's safe working pressure.

Quick Fill Conversion

By the selecting the quick fill conversion we will, swap your factory t-bar style filler for our quick fill unti, that comes with 
- A gauge built in at the front
- A twist collar to stop dust and dirt from getting in the fill
- A quick connect fill probe 
- The unit is also fully serviceable

This option is ideal if you are have the APEX regulator fitted to your air rifle, as your standard factory gauge will only read regulator pressure once the work is completed. This quick fill unit will allow you to continue reading fill pressure once the regulator has been fitted

HFT 500 Carbine

Over the last couple of years this option has grown in popularity. By selecting this we will fit either a 400mm or 300mm air cylinders then shorten your barrel to suit. 

This will bring both the overall length and weight of the air rifle down.

Please bare in mind this will reduce your shot count compared to the standard 480mm air cylinder 

Thread Barrel End

By selecting this we will machine the end of your barrel so it has a 1/2" UNF thread.

This will then allow you to fit most aftermarket moderators that are currently available or even a different air stripper or muzzle break.

This can only be done to those air rifle that have the shorter air cylinders fitted

Custom Engraving

We can engrave either our logo or a logo/image of your choice, this can only be done on wooden/laminate stocks not on 'tactical' or synthetic stocks. We can also engrave on the breech block of the rifle if your chosen design is suitable to be engraved in a small space. We love personalising rifles, the more imaginative and meaningful to you the better!

Cerakote

Cerakote is a thin film coating that will protect parts from corrosion or stop them rusting further than they may have already. Cerakote is available in a range of colours and can be applied to almost anything. 

Cerakote coating can be doing while your air rifle is being worked on.

This is ideal if you use your air rifle out does and in all weathers
