#1 JH Pardini GPR1 - Mk II

Mon Aug 14, 2017 1:38 pm

Only 1 person on the planet - is able to pull off something like this...

The UK's Premier Guru & Living Legend - who has the skills , engineering know how, talent and experience - to make the 2nd conversion even better than the first..

Congrats to the new owner who was really, really, quite patient... but well worth the wait

"Air rifles don't come much better than this. Much lighter than No1 for a number of reasons... titanium air cylinder, carbon barrel shroud, not least that amazing scope. The work Jon has varied out is absolutely stunning right down to the colour I wanted. The list of what he's done is endless, to many to list. Have a look at that hamster riser, it's a work of art. If I don't want to use the scope I can revert back to diopter sights no problem. Scope rail and swing out bubble are a master piece. I can go on and on about this rifle. As for accuracy it's good . The reason I just say good is I'm still getting to grips with adjusting the scope, so the inaccuracy is down to me and not the rifle,which is shooting fine, it was running a fraction hot, but that's sorted now. Accuracy out to 55 yards is promising to say the least. Might revert back to JSB 4.53, just to see if it makes much difference. Is it different to Pardini No1, well yes, in so many ways, you can get it to fit do well, just like a glove."

My only 'piss on the parade' comment would be - Walnut de rigeur...

That wood shade/colour makes it look cheap ass....shame Pardini did not think darker wood to pimp it up to 'luxury' status...

A Walnut with 'veins' exhibition grade could do... but with blackened dimples on lower half of hamster would be class :o

Would make all that anodized and titanium "pop" out even more :mrgreen:

Where do i start.

Long titanium cylinder with Fosters quick fill. To retain the side on look dust cap has an insert bronze anodised flush threaded in.
Cylinder tested to 350bar, operates up to 200bar.

Regs a Walther turned down and threaded up inside titanium extention running at 85bar on my old guage so probably 77bar.

Adaptor from reg extention to block anodised bronze.
Other power mods wont go in to due it it making life easier for the copiers.
Has an extrenal power adjuster but sits just above pistol grip fixing so no access.

Barrel sleeve removed and thick wall carbon fibre bonded on therefore doing something rather than the norm of looking the part.

Muzzle is threaded to accept the screw in silencer.
Also accepts dioptre sights via top dovetail.
Logo a bit large but done manually, its not like engraving thous deep 3mm cutter had to plough in 8mm+ deep.
Silencer is back venting blocked off in above piccies and would be quieter at shooting position whereas vented better down range.

GPR1 dont come with the front block dovetailed. This ones clocked up and machined in to take a bridged picatinny rail.

Rail is Picatinny/Stanag, no Weaver here that doesnt conform to any specs. Has built in tilt for 50 yard zero on most March and a built in swingout bubble level all anodised bronze.

Butt pad is an SE Ergonomic about the same price as the MEC that was on and genuine System Gemini the real mcoy.

Forend adjuster is my own prototype from 2015, already copied in plastic.
All adjusters to date will only give max drop at 90 degrees swing. For instance a long pivot centre one at 5" (125mm) will only drop 125mm, prototype drops around 120mm and 90mm centres far lighter and better clamping by finger and thumb, no presets that limits operation to unuable.

These are just the highlights, more has been done out of sight.

Glad to see some sort of improvement on the bolt to barrel sealing arrangement that was a nightmare on the first one, not forgetting the transfer port lack of seal 1mm clear! The bolt still has a load of slop and houses a magnetic stabilisor unadjusted.
Cant say the same for the dire machining off centre 0.75mm leaving an undsafe 0.52mm wall with original reg pressure against it at 70bar! Extreme remedy done on this one also, now safe.
Touch wood no breakages on this one the first was beyond belief a real pain like a Lambo, Ferrari,, Lancia, Maserati and Alfa always broke down in typical Italian fashion.

Must admit i was quite shocked how well this muther shot, as good as 1 in 100 Walthers that have been tinkered with.
Considering the extra length of titanium this balanced extremely well. Mainly due to the heavier titanium tube counteracted by junking the steel barrel sleeve.
Feels quite quick cant remember the stroke, its a nice rifle.
