HW110 Service & AT Removal
Just to say I’ve had a day off today, and with fairly perfect weather conditions for testing pellets.
Out of 11 brands and sizes these two were probably the best, only a 4 mph wind and any flyers were most likely pilot error by me. The consistency of this HW110 since you waved your magic wand at it is a total transformation. Superb.

HW110 Service, AT Removal & Left Hand Conversion
I’ve actually managed to get out and zero new scope to rifle. I just thought I’d give you some feed back.
Well as you know it was set too 11.2 with JSB 10.34gr. It’s settled down at 11.16 so spot on. I’ve put some QYS 9.56gr through it and it’s running at 11.33. Normally I’d expect it to be slightly lower but we live in the real world and things are not as black and white as we think. Got to admit the QYS are a much more accurate pellet by a long mile over 30 yards and as that’s what I shoot out to for rabbits it’s just the job.
Can’t tell you how pleased I am with how this is preforming. I will post this on the forum and let them see that a service from you is worth every penny and should be the first thing they do when buying a 110.

HW100 - Full Service
I just wanted to say how thankful I am for the fantastic customers service and brilliant repair and setup of my rifle.
I had major issues with my old HW100 .22 and thought it was only fit for spares but after speaking with them, I sent my rifle to them for repair and I have to say I am totally over the moon with the performance and results, they even tested different pellets and informed me of the best pellet for my rifle and also supplied a performance report.
My rifle is absolutely amazing now and after firing 3 pellets to zero it I hit the remaining 11 pellets centrally and constantly at a range of 33 yards, shown In photo.
These guys are brilliant and I highly recommend them due to their outstanding customer service and workmanship.

HW100 Carbine 250bar Titanium Cylinder
To say that I’m over the moon is the understatement of the year
Originally, my .20 was getting 5 1/2 mags so 77 shots
As I said yesterday I set the reg to 89bar and the hammer spring to 11.5ftlb using JSB Exact 13.73gr. This gave no spike whatsoever when the gun came off reg
Well filled to 250bar and at a range of 35yds time to test accuracy and shot count. I cleaned the barrel so first 3 magazines were inside a 10p piece. Once leaded in the remaining shots were all inside a 5p
Here’s a photo of my 4th to 6th magazines. The remaining 3 magazines were just as accurate.
So in conclusion, as accurate as I could want and now 125 consistent shots before dropping off reg. That’s one pellet short of 9 magazines. Absolutely amazing!!!!"

HW100 from BTAS to HWT Carbine 250bar Titanium Cylinder
First Impressions:
Unboxing the package that was carefully wrapped and Royal Mail Special Delivered to my house, it was immediately clear to see that the parts oozed quality. I had gone for the black tube option and it was finished to a very high standard. They had even sent me a redesigned HW brass inlet adaptor as they could see improvements, something which I believe is going to be incorporated into the kits going forward.
I do not wish to speak ill of other people’s work, but these parts were a marked difference in quality from the original BTAS offering….worlds apart.
We have all seen the videos going around the net of “home made” or badly made aluminium tubes going pop, or poorly machined parts. There are no such fears with this system. Tested to over 700 BAR with no signs of weakness and constructed using CNC lathe this kit was impressive stuff! There is also the added advantage being able to fill the titanium tube to 250 BAR giving the opportunity for an increased shot count.
My kit was a little different to HW100Tuning's standard one as I already had some BTAS modifications to my rifle so I didn’t need certain parts like the pre-chamber doubler, and my original HW reg core had already been removed.
In my package I received:
• A karbine titanium tube
• Tube to HW block end with drop in regulator pre-set to my requested output of 95 BAR
• Tube front end with upgraded gauge and fill port cover
• O rings for the ends (pre installed)
• O rings for the filler probe (an upgraded item)
• Lawrie spanner just in case I ever needed to remove the ends (although these are fine hand tight)
• The new brass inlet adapter with upgraded nozzle o ring to replace the original HW part.
The whole system took me under 30 mins to assemble. I’ve worked on a few HW100’s, but even to a novice this is no more difficult than changing a few o rings. If you can change an o ring you can fit this system!
Next was on to filling it up! Anyone familiar with filling an air rifle from a dive bottle may have come across the strange effect of “Thermodynamics”. As you fill a bottle or tube it gets warm. When the tube or bottle cools, there can be a slight pressure drop. This can give the illusion of a leak, but this isn’t always the case.
After filling the new tube to 200 BAR and leaving for an hour of so my gauge showed a pressure drop of about 10 BAR and settled at 190 BAR. I topped it up to 220 BAR and then left it for 2 days to check for leaks.
I am pleased to report that the system went together first time, with no leaks, no adjusting and no problems. Ask anyone that knows me…I can break anything! I own 3x electrical engineering companies in the UK and my own staff won’t let me use power tools (its probably better this way) but even I fitted this system with no problems.
Id like to think I know a bit about airguns, and in particular, Rapids, Air Arms and HW100’s, but the instructions provided are fool proof for anyone to use….i reckon my wife could do it….but that would mean she has to go in my gun cabinet and she thinks I only have the one!
Testing: HW100Tuning had pre-set the reg to 95 BAR, leaving me just the fine tuning of the hammer preload to set my desired power. I tested JSB Exact Heavy and HW Magnum pellets as two of the heaviest offerings to make sure I didn’t run over the 12 ft/lb limit for non-FAC holders. I settled on 700 fps as being both consistent and offering a power of just over 11 ft/lbs.
When running pellets through the chrono (Alpha F1) I noted how consistent the reg was. 700, 703, 701, 699, 700 etc. The figures didn’t move further than 3 fps from my desired setting. Again, impressive stuff.
Reassembling the action and stock, I moved indoors to shoot a few targets with the HW Magnums just to get an idea of the potential accuracy of the gun before I come back another day to do one of my famed pellet tests (I enjoy these immensely). Initial results showed that the accuracy potential is there I just need to find “the pellet” (14 shots)
What was impressive, is that I had rattled through about 7-8 magazines with chrono testing, roughly zeroing and then a few targets to assess potential and I still hadn’t hit the reg pressure of 95 BAR. I would say from experience that this was a good 2-3 mags more than I would usually expect from a standard HW100K. The air usage, or lack of it more like was fantastic. Once I find the right pellet this is going to be a deadly combo.
