Air Arms FTP900 full trigger rebuild service & new regulator.


Hi Mike,
Managed to shoot the ftp900 yesterday in a club comp I didn’t manage a great score but that was down to me, not the rifle.
The trigger is much better to use now than before, & it’s so much better with the air gauge re-fitted as I can now keep

track on the amount of air used. Checked the FPS over the Chrono and all’s well there and no air leaks.
Many thanks for all the help,
Best regards

Theoben Rapid MK2 .22cal FAC service & gauge/quickfill

Theoben Rapid Mk1 .25 cal FAC
service & gauge/quickfill



Good Morning Mike.

I thought you may be interested in a couple of updates on my Theoben Rapids you recently serviced

& fitted with quickfill/gauge units.Its great hte unit gauge and fill is OUTSIDE THE STOCK
So no modification to woodwork stock NEEDED.
The Rapid Mk 2 - 0.22 cal FAC it's shooting beautifully the gun is shooting like a dream - thanks to you.

I took the Mk1 - 0.25 cal FAC out last night, 1st time 'in anger' pest control for farmer friend with a rat problem.
In all the years I've had it, it's never shot better, laser like accuracy and hugely powerful.
Truly a formidable beast, thanks to your expert work.

Theoben Rapid MK1 .22 Calibre with low power issues.

Hi Mike.

Wanted to let you know the gun is shooting superbly, I'm pleased with the accuracy and consistence with the power.

I got 100 shots from the buddy bottle fill you did, I suspect I could get more and will test.

It is now much improved with your Regulator/Quickfill unit fitted. Before the power curve was just non existant.

As soon as the weather gets better I hope to do some HFT at a local club so will see how I do.

Thanks again for an excellent job.

RAW TM1000 .177 Target Rifle with consistant accuracy issues.


Hello Mike.
Just wanted to update you so far regarding the servicing, power curve testing & barrel work you carried out
on my Theoben RAW TM 1000 .177 target rifle.

Taking it to the range on 2 occasions so far, I have managed to get through several hundred testing shots.
I am happy to say the rifle is performing very well. It feels much more consistent, with the high and low shots

At my 55 yards bench rest shooting away from zero being greatly reduced.
I feel that any errors now are down to my shooting, the barrel issue internally you found, or bad pellets from the tin.

I have attached some test targets for you. The 4 middle targets have had ten shots at each using

JSB Exact Diablo .177 8.44gr 4.53. From 7:30am the weather on the range had a low breeze was overcast with light drizzle.

I took the pellets straight from the tin, as you can see the groups at 55 yards are pretty good for the conditions

I was shooting in. There are no unusual flyers outside of the targets over 40 shots.
I feel that with decent conditions and sorted pellets the groups would be even better.

I would like to thank you for your work servicing my rifle, supplying all the curve and power data and the barrel re-working.

I feel much better shooting my rifle now thanks to your hard work.

Falcon Light Hunter Service Check Power Curve Fill/Empty Position & Shot Count.

Webley Axsor Regulated. Service Both Rifle & Regulator Reset Power Level.

Hi Mike,

I thought you'd like to know that on Saturday morning I spent a couple of hours zeroing and then using the Falcon on a variety of targets. Once it had settled down after the first 5 or so shots, it held a very good group at 20 yards, & pellets only began to drop after another 40 or so shots, as you said they would. Overall I was both very impressed with it.
Thanks very much again for servicing both rifles. Supplying all the data & feedback, & preparing them to such high standards.

Best wishes.

P.S Thanks for taking on the Falcon as I know you normally do not offer any work on these.

RWS Excalibre .22 FAC Conversion from sub 12ftlbs .

Message recieved on completion.
Hi Mike.

I just completed the zeroing and checks on the Excalibre. To say I am delighted is an understatement.

Set up targets at 33 yards (to make the clicks accurate multiples). Shot a string of 28 (4 magazines) to zero sights. Pressure fell from 200 to 150bar. 53 pumps restored it to 200.

Final group of 5 shots on a bag rest 20mm c-c at 33 yards. That's just over 2moa on a windy day.

It also punched holes through the 1-inch pine board used for the Shoot-n-C targets. Pellets were JSB Jumbo.

For me, a perfect compromise. Plenty of power, extremely accurate and as efficient as I could expect.

Thanks again for such an excellent job. Have a nice weekend.

Hello Again Mike.

I thought you may be interested in the extended tests I carried out this week. The results surprised me.

I used JSB Exact Jumbo throughout as they give high m.e. and are, with Accupell, the most accurate of all the pellets I have tried in the FAC version.

Starting at 200 bar, I chrono'd and measured reservoir pressure down to 100 BAR. The results were:

200 BAR 781fps 24.7ft.lbs
190 BAR 798fps 25.7ft.lbs 6 shots
150 BAR 824fps 27.4ft.lbs 22 shots
140 BAR 831fps 27.9ft.lbs 5 shots
130 BAR 831fps 27.9ft.lbs 5 shots
120 BAR 826fps 27.6ft.lbs 6 shots
110 BAR 787fps 25.0ft.lbs 6 shots
100 BAR 728fps 21.4ft.lbs 7 shots

So 200-110 BAR gave 50 shots, all at between 25 and 28 ft.lbs. Accuracy was superb with no discernable change in zero for 50 shots at 35 yards. All groups have been around 2moa using a bag rest in light wind.This proves that the main consideration is accuracy and FPS is secondary as the above test was an MAX ES of 44 FPS !!!!

Just for fun I then recharged to 140 BAR and measured the drop at exactly 150 yards (field gate to field shelter = exactly 150). It measured 63 inches which is precisely as predicted by Chairgun, proving the relatively high BC of the JSB Jumbo pellet.

I never expected such a high shot count with such consistently high power and accuracy. The valving and gas flow must be very efficient.

Thanks again for a job well done .

Mikes comment here is would aim to keep my ES within 25FPS but I have had this sort of result from several air rifles.

Maybe we are too wrapped up with the constant FPS bit!!!!!!!!!

HW 100 Carbine shot count improvement from 30 shots to 60 shots.
Hi Mike,
Just a short email to thank you for your help, which resulted a dramatic shot count increase & improved pellet velocity.
When I first contacted you, my air rifle was only producing a shot count of around 30 pellets with a low velocity.
It now gives me a minimum of 60+ shots & much improved more constant velocity - FANTASTIC !!
Thank you for your excellent help.
Best regards

Airarms S410 .22
Hello Mike,
Just to say a huge THANKYOU. My AA S410 is shooting pellet on pellet and reaching 80+ shots all landing in the same place. This is remarkable for a Carbine. Having two Gunsmiths claim to have serviced my rifle then find it not the case, I was as you know very frustrated. You explained and showed me what was wrong with my rifle, then told me what was missing during its supposed last service by a Gunsmith. I was shocked at how I had been ripped off but more shocked at the results shown on your service etc. It is fantastic. You are truly a great precision engineer. I am so pleased you were recommended to me.
After crowing yesterday at the Gun Club about my pellet on pellet groups a few Members asked for your details, & please be assured I will be recommending you too many more airgunners.

Theoben TM1000 .177 Target Rifle Issues.
Hello Mike,
just a HUGE THANKYOU for all the fine work you carried out on my Theoben TM 1000 which I put it back into FT use today.
RESULTS were my best score so far this season (33) so many thanks for your excellent work.
I thought I would have a problem sourcing an engineer competent to service my rifle and regulator, until the FT/HFT
Guys in Cornwall recommended you. Thanks again.

RWS Excalibre .22 Sub 12 to FAC Conversion.
Hello Mike,
Just a quick update on the Excalibre that you tuned to FAC for me.
I have been very impressed with the flatness of the power curve over 35 shots, I know you stated 32 shots from 195-125 bar but I have found an extra 3 that don't show any POI difference at 65metres!!!
I was surprised at the quietness of the setup which puts my BSA R10 sub 12ftlb to shame even with the same moderator.
I have now put about 500 shots through it and am now able to happily report 8 shot groups at 65metres of sub 20mm diameter using AA Fields 5.52's straight from the tin.
I know the gun was a bit of an old dog with more than a few war wounds inside and out but now it shots like a new gun worth twice as much, at least I'm not worried about actually using it and getting it scratched or wet!
So in short I am impressed with what you achieved with this gun.
I must say it is nice to have someone as knowledgeable and genuine working with airguns as yourself as it can only help promote the poor image of airguns that many hold.
Many Many Thanks

Airarms S510.22 FAC Extra.

Hello Mike,
This morning was the first opportunity I've had to try out my air rifle since I picked it up from you.
I have to say I'm impressed with the difference in the gun since you tweaked it, I zeroed it in at 35yds and put all ten pellets in a 1" circle then moved the target out to 45yds and again same result with a slight hold over.
I have purchased some scales to weigh my pellets and have to say the AA heavy fields were very consistent at 18.5 grains apart from two out of 250 which were different weights. More disappointing were the amount of misshapen pellets in the tin, I had to remove almost a third.
Thank you for sorting my gun out I will certainly recommend you to my shooting friends.

Weihrauch HW100 .177 Varying power levels regulator problems & accuracy.

The owner had a suspicion that it is not firing at anywhere near optimum power,so the brief was to fully test & service the rifle then field accuracy test to 50 yds supplying my preferred pellet type test targets ballistic data reports.


Hi Mike
I finally managed to get to the indoor range last weekend the rifle now functions perfectly without any problems thanks.
Getting 80 regulated shots from 200 down to 100 bar, the rifle is performing exceptionally well.
Managing to get consistent half inch groups at 35yrds without having to work too hard, in fact it became quite boring
I moved my target to 55yrds to give me more of challenge, still managing to hold good groups.
I also changed to AA Fi
elds 4.52 as you suggested, and I would say that they were marginally better than my standard pellet.
So it's AA Fields 4.52 for me in future.
I am really pleased with the work you did for me, so I know where to go if I have any future problems.
I will also recommend your fanstastic service and constant feedback services to any other Airgunners who may require them.


SAYS David Cheshire.



I Look Forward To Hearing From You.
