Pulsar scope rail

A scope rail attached to a shroud looks an interesting technical feature, which, assuming it works, will be interesting to examine.

​I am a Daystate fan, though not a fan of electronic rifles, I am interested in the idea of the Pulsar (though the laser should be replaced with a rangefinder) but only after I saw a picture of the rifle outside the stock.....which looks like something Hans Solo would use. I am tempted to buy a rifle (after six months: always better to wait for all manufacturers to correct initial faults) and just add a small butt pad/electronics cover to the basic rifle. Their stocks look a disaster.

Then the front of that rail is something else that I am likely to remove.

The intermount scope rail connects to the breechblock and a support that screws to the barrel. Six rews on the barrel and two into the mount. This is gold on the OS version, so you can see it more clearly.

This means it is quite heavily supported, and although the front end can be flexed, the CAD designer insisted that it woild be rigid enough. The engineers doing the development were at first also a little concerned, but trials have proven the CAD design to be correct. ATB tony belas (Daystate UK)

The scroud is a hollow tube which floats on o rings, so securing it there would do nothing and could add another potential problem. The airtube below free floats and is alloy so we don't want to attach there (as we did on the SR92, which caused problems ) As i said, we have not seen any problems with zero shift and the accuracy is great, if it wasn't we would have rethought it. All the best, Tony

I've been struggling with POI shift for the last couple of months with my Pulsar. It's been a lengthy and laborious process to get to where the problem is. I even sent my scope off to be checked/repaired to be informed that there was nothing wrong with it. What is happening is this:- give the scope a sharp tap on either side and POI shifts by half an inch at 10 yards in either direction. Never any more than half an inch and repeatable time after time.
Investigating this strange behaviour further, I discovered, using a feeler gauge, that the clearance under the front of the rail would increase on the side of the tap, the gap on the other side decreased by an equivalent amount. When this happened, the POI shift was confirmed by a shot. To compound the problem, if the rifle is left for any period of time in it's bag, leaning against something hard, or suffers a knock during transport, the rail will move.
This has cost me a qualifier to a competition when the rail suddenly moved during a shoot leaving me not even seeing a POI at 30 yards, the expense of having my scope tested and way too much frustration.
I've spoken to Daystate and had an all to brief but pre arranged meeting with Simon Cockayne, who has promised me a new rail, theorising that it's the rail that's at fault without even looking at my rifle, which I had with me. I've accepted that offer but it's not the rail, it's the design and method of fitting it to the rifle.
The rail can rotate, by the amount of clearance in the bolt holes, around the circular barrel collar (the gold bit on the Oro). 
The designers should have utilised the dovetail on the receiver end of the action to mount a properly dovetailed rail, end of!

If Mr Belas reads this..........Very very disappointing Tony, and shockingly poor customer care on the part of Simon. There is NO technical or warranty cure for this fault, the rail fitting needs to be redesigned and fitted properly.

After spending the best part of my 2 grand on this rifle, I now have to source, have machined to fit, new parts, to make an accurate air rifle.

I have had an issue with this on my ORO every time I got my pulsar out of my case I had to re zero my scope and I don't mean a few clicks it didn't take long to figure out that the rail is ridiculously frail and lacks support the only way to avoid having to zero the scope everytime you put it in case is to treat it like a a new born kitten. iv never designed a air rifle but even I can see it's a major design flaw that should of been picked up during the CAD design before the fist milling tool span. unfortunately I am currently trying to get my money back I don't want a replacement rail that's not going to rectify a thing.

Sorry to hear any tale of woe but just crying 'design problem' doesn't alter the fact that the intermount on your pulsar has 1000 friends, none of which seem to suffer this, nor did the three I shot in Octobers extreme bench rest or the one wyan (a Daystate tester) shot at last year's world Ft match. Quite apart from the two years of testing carried out before hand.

I know it different and that can be disturbing, but you need to take another look. Sure you have a problem but this is not a good way to fix it. Speak to the guys at aoa, they are capable and willing to help any reasonable person.

aoa is a a tad to far for me as im in Cheshire UK, maybe you're correct and its pure coincidence that the only rifle I have with a scope rail that you can flex with one finger has a scope accuracy problems. The bottom line is the pulsar is a great rifle apart from a couple of things but ill never have confidence in the rail you can say it's not a problem but I don't live far from you Tony come meet me at my local shooting club in warrington and I can 100% show you it is a problem and I can shift the scope POI with one finger. If you come and im wrong wouldn't that be a great way to put the rail douts to bed on the forum.

PS I know this is not a good way to fix the problem, im no longer trying to fix the problem because daystate just like you deny it is a problem hence why I have given up hope and am getting my £2000 back.

Sorry assumed you were American as this is an American forum. I'm currently working at the British Shooting Show I'm Coventry, but you are welcome to come here. We have a pulsar on the range, which if it's a design fault would have to be the same. Though the hundreds that have shot it since Friday wouldn't seem to agree.

Take you rifle back to the dealer, we will collect and check it and if it's in good condition I'll make sure you get you're money back.

All the best. Tony B

 'if it's in a good condition' can I still class it as new if iv only ran 100-150 pellets thru it since purchasing from new on 08/01/2016 regardless I wont be sending it back to daystate at my own cost iv already spent a little under £7k on daystate alone between 2015/16. this last week I have completely changed my opinion on the company an i was a massively loyal customer im shocked at Tonys Belas's attitude towards people who dare question what we feel is a design flaw believe me when I say not all the clever people work at daystate there are some some others out there with logic in design. 

"DaystateUK"Sorry to hear any tale of woe but just crying 'design problem' doesn't alter the fact that the intermount on your pulsar has 1000 friends, none of which seem to suffer this, nor did the three I shot in Octobers extreme bench rest or the one wyan (a Daystate tester) shot at last year's world Ft match.

If I have 1001 friends does that mean im correct and you're wrong? just because you think it" has a 1000 friends" (does it have its own facebook page?) dosnt mean there is not any faulty ones. Lochen's ORO is number 059 my ORO serial is a lower number than that so out of the first 59 pulsars at least 2 have the same fault. im not crying tony im just out of ideas have spoken to daystate and being tolled theres nothing wrong with it just send it to us at my own cost pee's me off it cost me £2k and nobody at daystate is bothered and the boss is just insulting and rude behind a keyboard (and you don't even know who you insulting) im more than willing to show you the problem privately and face to face if your willing to.

Tony take that Pulsar to a private range when you get back to the factory away from us crying customers and zero the scope, Then apply a tiny bit of pressure to either side of the scope with your little finger for a second, then shoot the rifle I know you wont come on hear and admit it but at least ill know your aware its a problem if you wasn't already.

Now this is not a wich hunt I have many Daystate's and they have all been flawless other than normal serviceable components that you'd expect this is the only daystate iv had a problem with and to be met with this response from the boss of the company in public domain is really disappointing as iv actually stuck up for daystate in the past but now I have to agree with some of them the pulsar is the last new daystate I purchase im not supporting the company any longer.

I was at the shooting show on Friday where I met with Simon Cockayne. At his request I brought the rifle along to a promise of time with him on the range and a resolution. All I was offered was a replacement rail and a statement from Simon that he 'didn't have time'. When I initially contacted Daystate about this problem and Simon called me last week, I thought I was embarking on a ''good way'' to fix the problem. Now I feel let down and left with no alternative but to challenge your reassurances in this thread that the design is 'good'. I AM a very reasonable individual, and until I read your first response Tony, wasn't even remotely cross about this particular issue. Now I am. How dare you intimate that anything in my post was unreasonable or that any of my actions to date have been unreasonable. I've made every effort to be reasonable in contacting Daystate first of all, taking the rifle to Coventry, as requested, to no or little avail!

Along with ozone08, I think the Pulsar is a fabulous rifle. I'm also certain that the mounting system has many fans, I was told as much on Friday. However, along with ozone08's, mine does move, has been proved to move, has been measured as to how much it moves and, Daystate were given an opportunity to confirm the truth or otherwise on Friday but didn't take it.

Now I'm afraid, I also want to return the rifle for a refund. Perhaps you'd be kind enough to also contact the Airgun Centre on my behalf? 

@Lochen did the replacement rail work ?

Im glad to hear it Bluestone want to swap ?

To be honest I wasnt that fussed about the problem I just expected it to get sorted out the main problem is the fact that the company wasn't really lestening to me when I first got in touch almost 2 weeks ago and then I noticed this post by lochen last night and he seems to be in the same boat if not worse he had to go down to Coventry to meet simon and left no better off and more out of pocket and that's unacceptable and to tip it off lochen signs into AGN this morning to a few pretty harsh replys from the top brass sent from a phone saying things like our working rails have more friends than your rails so we're right and you 2 are wrong

Personally this forum shouldn't be the place to go back and forth with DayState. It's not fair to DayState or yourself because nothing is getting resolved, not to mention the issue being discussed may be an isolated incident.
