Should I go full-on into the head-spinning technicality of the subject, or should I simply shoot the thing and write about a load of figures and group sizes? More basic still, should I offload the test altogether and let Nick Jenkinson do it? Nick has a technical affinity with pretty much everything he touches and I’m forced to concede that he’s the ideal range companion for a rifle as stuffed with computerised bleepery as the Daystate MK4. Yet, I kept it, tested it, and eventually almost fully understood it. Almost. This test has been an epic encounter, but I feel I’ve emerged from it a wiser man and I didn’t break anything. This rifle will indeed find its way to Nick for a future examination, when you may rest assured that our man will probe its every techno-crevice and take its micropulse at hourly intervals, until the full facts are laid bare. Until then, here’s what I made of it. THE BASIC EXPLANATION The pre-charged pneumatic Daystate MK 4 is a logical development of the groundbreaking MK3, which introduced us to the computercontrolled, battery-powered, electronicallyregulated sporting air rifle, courtesy of the talents of David Snook and Steve Harper, in collaboration with the Daystate technicians. This bold surge was orchestrated by Daystate’s sales and marketing manager, Tony Belas, and it’s the Belas baton that has conducted the orchestration of this remarkable rifle’s development. Believe it or not, it’s been five years since the first MK3 motherboard was given life and delivered to the airgunning public, with A, B, C, and D variants upgrading The ballistically brillia nt and enhancing the performance of brain of the Daystate MK4. the MK3 in carefully crafted stages. So why is this new rifle not an Etype Mk3? The answer is refreshingly straightforward; the MK4 is so different it THE MK4 MAP deserves its own MK number. Before I explain In essence, then, a MK4 is indeed a those differences, I really must do a MK3 reprogression of the MK3, and it shares the 10cap for those who have yet to plug in to the shot magazine, rechargeable battery (albeit an whole electronic airgun deal. improved version) and the security key which What we have here is a shooting system switches the system on and off. The essential that uses microprocessors to control the difference in the way the MK4 works is that functions and performance of the rifle. Where the rifle adjusts itself for every shot. On-board once spring-powered strikers clouted firing sensors monitor the pressure in the air valves to release stored air for each shot, and reservoir and re-jig the MK4’s firing system to levers and sears tripped the trigger suit. These sensors can detect a shift in mechanism to release them, this particular pressure as low as a two-hundredth of a bar, Daystate system (the company also produces and once a change is detected the computer ‘mechanical’ rifles) uses an on-board calibrates the valve function to compensate. computer to ping open and closed an The result of this constant compensation is electronic firing valve and to activate the nothing short of spectacular. trigger.

I may have gone a bit kittenish at the end there, but you’ll get my drift. Anyway, the MK4 does things its own way. Don’t worry, it’s all explained for you. 2008 AIRGUN WORLD 17 4-ward move 0808:Take this down 0107 3/7/08 10:22 Page 18 Forget the technology for a moment – this is one good-looking sporter. would produce around 65 shots from its recommended 232-bar charge. In MK4 guise, the rifle produces a magnificent 160 shots from the same charge. Read it again; what would be a 60-plus shot system, is now a 160-shot one. In a .22 example, we upsize from 80 shots – and I’m talking perfectlyregulated shots here – to 185, and very probably counting. While we’re boggling at the uprated shot count, we may as well swoon over the fact that this incredible air-efficiency brings with it other benefits, such as reduced muzzle-blast, plus lower turbulence around the pellet and the increased accuracy that comes with a pellet having a smoother launch. Like the MK3, the Daystate MK4 comes with a whole range of control and alert options accessed via the interaction between the rifle’s safety-catch and trigger, all of which are explained in easy-to-follow detail in the information Daystate provide with each rifle. I’ll cover those options now, before getting stuck into the real-world shooting report. Stage 1. This is a magazine counting option that, unsurprisingly, lets you keep track of how many magazines’ worth of shots you’ve fired. Stage 2. The rifle’s manual/resettable safety-catch has a red light inside it. This option lets you switch off the light. Possibly the least-crucial development in the entire venture. Stage 3. This mode alerts you to the number of pellets left in the magazine. The safety-catch light will flash on the 9th shot and you’ll get a ‘bleep’ on the 10th. Stage 4. The rifle’s pressure sensors will alert you to the fact that there’s not enough air in the rifle’s reservoir to continue shooting. If you ignore the alert, the rifle will refuse to fire. Stage 5. You have a 16-stage powervariation option. This can adjust the rifle’s power from 11-plus downward, or from 30 ft.lbs. downward if the rifle is an FAC model. Stage 6. This switches the rifle to singleshot mode, and the safety must be activated between shots or the rifle won’t fire. Stage 7. This allows you to return the rifle to its factory-programmed default state. There’s more to the seven-storey options than this, but basically this rifle owns you. I get the impression that, while I’m still useful for pointing and triggering, the MK4 would rather I didn’t get in the way too much. Or than could just be me. ON THE RANGE I have a ton of features yet to explore but I’m in need of a break and I’ll do those as I go through the MK4’s performance. First the simple stuff and filling the rifle with air. This has been made even easier thanks to a shallow recess in the underside of the barrel shroud which gives clearance to the charging adaptor. A small touch but welcome, and proof that Daystate tend to the basics as well as the rocket science, which is reassuring. I had the recommended 232 bar installed in 30 seconds or so – I’m a ‘trickle-fill’ sort of PCP shooter because I prefer a full charge and I don’t like to rush compressed air – and that gave me well over 150 shots to chrono’. I managed 80 consecutive shots before tedium took me away and I had to shoot some target cards before I went chrono’ crazy. I truly don’t know how Nick Jenkinson does it. He’ll blat away for hours, logging shot after screamingly dull shot, until he’s got his database well and truly sorted. I suppose I should, too, but I’d rather bite my own face than give more than an hour of my life to a chrono’ test. It’s a failing I know, but that’s the way it is and I’m too old to change it now. Meanwhile, the shots I managed to log were impressively monotonous in their output. They had 11.3 ft.lbs. as their standard, and they blipped on that figure or very near offer throughout the entire chrono’ run. The official variation was + or – 4 f.p.s., and that was with Daystate pellets straight from the tin, so some of even that tiny deviation was down to the pellets rather than the rifle. In practice, shooting a MK4 means that shot-to-shot consistency isn’t a matter for your consideration. This in turn means you can concentrate on the matters that are, such as windage, rangefinding and setting up the trigger for human use. Yes, that trigger. If I can have a tiny word in the ear of Daystate’s trigger testing specialist; please send out your MK4s with the trigger set for normal human rather than neurosurgeons, there’s a nice chap. I’m told that each trigger is set at a factory pull-weight of 8 ounces, and it can drop a couple of ounces below that should its user have the dexterity of a street magician. I’m saying 8 ounces is too light as a starting point, and the phenomenon I call ‘trigger fear’ is there for the taking. Trigger fear comes when the let-off is so light that the majority of the shooter’s attention is diverted to the trigger in fear of tripping it before the shot is fully composed. This isn’t a good thing at all. Releasing the shot should be accompanied by full The Daystate MK4 ST. Has it re-defined the term ‘ultimate sporter’? There’s bafflement everywhere with the MK4. 18 AIRGUN WORLD 2008 4-ward move 0808:Take this down 0107 3/7/08 10:24 Page 19 DAYSTATE MK4 Lock ‘n’ load. You put the same in but you get far more out with a MK4. confidence, not trepidation. Perfect trigger use is an almost subconscious act, carried out when the shooter is as relaxed as possible. You can’t do that if you’re even slightly worried about touching-off the shot too early. Yes, the trigger can be set perfectly by a single adjustment of a single hex-wrench, and that took me but a few seconds to do, but I’d still like to see a more realistic factory setting. I shall be having words about this and I expect the hair-trigger freaks out there are scowling at me even now, but come a frosty morning and with it the sausage-finger syndrome, and they’ll be shaking their heads in sorrow, don’t worry about that. Being set too light apart, this trigger is a wonderful thing, and short of a go-anywhere trigger blade, which I’m now told is an optional extra, it has to be considered perfect. Also a candidate for the ‘perfection’ tag, is the MK4’s bolt-handle and the 10-shot magazine it helps to feed. There’s virtually no effort required to cycle the MK4’s boltaction – due to there being no internal hammer spring to compress – and if you’ve never used an electronic rifle you’ll find yourself pulling back on the bolt far more vigorously than you need to. This tendency soon passes and the whole system glides along at the flick of an unstressed finger. The magazine is the latest specification, low-profile version, which permits the fitting of lower scope mounts. It also feels more precise than previous versions, although I’m struggling to pinpoint why, and to be entirely fair I’ve never had problems with a Daystate magazine. I especially like the twin magnets that locate and fix the mag’ position, and that of the single-shot pellet tray, which is provided with the rifle. The shrouded barrel contains newlyspecified baffles to reduce muzzle-crack, and while this isn’t the deathly-quiet moderating service offered by some add-on units, each pellet emerges to a technical ‘hiss’ rather than anything approaching a ‘bang’. Seriously, FAC models excepted (but grudgingly so) if you add another silencer to this rifle you’ve got to have a word with yourself, and that word is ‘don’t’. Read Tim Finley’s excellent piece on silencers in this issue and you’ll see the sense in preserving the handling of a rifle, and even its looks, over a mania for ultimate hush. THE STOCK Gary Cane designed the MK4’s woodwork and, as ever, he’s made a fine job of it. It’s produced in hand-oiled walnut by Minelli in Italy and there’s a sporter option, too. Note ACCURACY This report, though essentially the most important section of all, is almost as dull to read as chronographing. Being behind the MK4 as it slots pellet after pellet into tiny groups downrange is still as satisfying as ever, though. This is a truly match-accurate rifle with a brand-new specification barrel, and nothing on the sporting market will outshoot it. I clocked six groups of sub-15mm at 50 yards on an indoor range (warehouse actually, but it served its purpose) and every halfcapable shooter within range of a benchrest, a himag scope and a Daystate MK4 could do the same. How It’s that sort of rifle. No, wonderful to find a dirty it’s better than that, great bolt it’s a mind-bogglingly anchoring magnificent rifle and technology marks yet another to timber. incredible goalpost move from Daystate. Not just a safety-catch – it’s a command switch.

As it stands, the stock is pleasing to eye and hand, and I was particularly pleased to see that it’s attached to the action by a dirty great single bolt.
