Right, that's it, you can't borrow it! :D

Quite obviously the gun you are all seeking has to have John Bowkett designed valving, a Walther Lothar barrel free floating but resting on a plastic spacer with a loose band to absorb any knocks - it is called a Falcon Lighthunter. Not only was it the first gun ever to achieve a 60/60 at HFT but also won the mighty Oaks Open a few years back in the hands of a youngster called Spencer.

Are we talking out of the box or home tuned

Not so much "out of the box" but more fundamentally, which unregged gun has the best fundamental building blocks to make the ultimate gun. I hadn't thought about the daystate mk3 sporter, it's a bit long in the tooth now. I'm thinking of getting a cheap EV2 with a dodgy reg (shouldn't be hard) and fitting an a unregged valve system like the s400 and tearing out the reg. Job done.

Sounds like you have already made your mind up...what a poor choice....The Mk1 Rapid is the rifle of your little private dreams sonny! XX

I wouldn't no where to start with the reg, even if I did have the seals required

One word; spare reg...

Bob or Chris, your more than welcome to try my ultron out and see if it fits the bill. I know the breach is bolted together so no worries there. With the new se models coming out there are quite a few ultras and scorpions for sale. Then fit a barrel of your choice.

Ideally out of the box as not all of us can "tinker" like some others!

Or even better a good unregged gun

I repeat myself, Mk1 rapid!

I like the idea of the rapid but I don't think I've ever seen one being used in competition?

The daystate huntsman I had was a good gun , had my first clearance with it and that was unregged. Not the best stock though.

The Huntsman is a nice gun but a little too light, it would benefit from a longer cylinder. It only has pseudo 2 stage trigger, similar to the BSA, but still works well with a crips let off. Lovely little gun but feels a bit fragile, unlike the price tag which heavy duty.
The mk1 rapid had a rubbish trigger, something to do with gamo I believe.

The main thing that lets the MPR down it the 'junior' size stock. IMO it's the easiest rifle to tune, service & shoot out of the box though. I have had many different rifles over the years (not as many as Bob though ) from a Steyr to a BSA lightning & I actually bought back the MPR I sold as most of you know. (& the kind chap had the cheek to charge me more & f@%k the barrel on it)
I wouldn't sell it again.
Polish the trigger sears, add crinkle washers, polish the firing pin & hammer rail & it will shoot as well or better than a regged rifle once it's into it's sweet spot. I also run a lighter hammer which makes it just that little bit deader.

Also the new MPR's aparently seem to have a new style firing pot or they have changed something else internally as the shot count & fill pressure has changed (for the worse) apparently. I personally haven't seen the inside of a newer model so not sure.

Interesting, the firing pot has always intrigued me, what does it do and why do other manufacturers not use the idea? As far as I can see its a clever way of stopping debris and rubbish reaching the firing valve.

I have no engineering knowledge at all Bob. It could almost meter the air as well ?
I know playing with hammer weights, hammer spring tension & the firing pot length can 'tune' the rifle better. I can tune mine to have 90 'usable' shots from a 180 bar fill, but I choose to run it how I have it set now, fill to 165 bar & I get 60 shots under 10fps difference with the pellets from the tin (in the batch I have now).

I understand what you say about metering the amount of air but I can't see the advantage as the pressure still drops the same. The s400 hammer does need looking at, the Daystate huntsman and merlin have the slingshot hammer which is a clever idea. It reduces hammer bounce and gives a lot more shots. But I am also a fan of keeping things simple. The S400 is brilliantly simple.
