HW97 fitted with Nick Gibney Hybrid piston

- Having shot Nicks astounding HW77 he told me that he was experimenting with a hybrid alloy skirted piston kit. I ordered one and fitted it - an amazing transformation! The gun is superb to shoot. Very little recoil, almost no sight picture movement and a lovely fast shot cycle.

Know this is an OLDER video. It's just amazing all the tuning possibilities for these Weilhrauch rifles!
I have received my HW97k and it's shooting fantabulous and it's all stock from factory!
So if and when I do a tune (hopefully by a professional on these beautiful guns) I will be noticing a big difference of shot cycle as I can see with your great informative videos...
I've done quite a bit of PCP shooting with great guns, and soon as I started up with this HW97k I noticed that I really had to get the experience of shooting springers. I noticed after some weeks of shooting I finally am getting the gist of how to properly shot these beauties...
At 30 yards my groups are pretty incredible, actually they are starting to look like PCP groups lol.:-) :-)
Nothing compares to shooting one of these, I can imagine what a tune would do in the future!!!!
Loving it!!!
Thanks to your informative videos I decided to get one, and now I don't shoot pcp for now, it's just that I don't want my springer shooting style affected at all lol.
Would be nice to have some velocity measurements and grouping test before and after to go with "outstanding, fantastic etc" Reducing the mass of the piston by almost 100g and increasing preload may very well lead to massive loss in exit velocity, if not done right.
Lovely rifle even better now so smooth and quiet Nick K kit in wow .. PCP territory.. With the Nick G
Amazing that is , Guess I will bump into Nick at some point , as I shoot every wk at the Greyhound, believe he visits on Sundays , I usually go on Saturdays, might treat my 97 to abit of his magic in the future cheers Shane
Very nice, thanks for sharing!
The Best !!!
I guess we'll just have to take your word for it on that one
Awesome
You need extra pre load to reduce piston bounce after lightening the piston. Low start pressure pellets( JSB RS/ Falcon Accuracy Plus) will also reduce piston bounce. It is my belief that the earlier the piston bounces during the firing cycle the less efficient the system as the piston and projectile will not be travelling in the same direction for as long. I also believe that lightening the piston too much may give it a harder landing as it is accelerated faster and can be detrimental to what you are trying to acheive. For example, you may reduce felt recoil but increase surge as the piston finally stops against the cylinder end.
Of course, I may be wrong in my assessment but everything in spring piston airguns is usually the result of a compromise and when something is added in one area something is taken away in another. This is what makes tuning spring guns so absorbing. There is no right or wrong as it is the shooter who determines the results of tuning these truly mysterious machines!
May I thank you for taking your time to show your rifles in various states and tunes. And for brilliantly doing so.
P.S. For me a longer spring of thinner wire gives a nicer firing cycle than a shorter spring with thicker wire. I recal the first HW77s and FWB Sports used this concept.
watched this vid (and probably all your vids) over and over. thanks! this kit seems the best kit ever regarding to reduce recoil. does Nick Gibney also sells these to strangers?
+Heidy Wieland - Nick does make parts for anyone. However this is his hobby rather than a full time job. If you want to talk to him,he can be contacted via the airgunbbs forum.
Good morning, I have seen your videos and I really like your experiences, so I want to ask you a question, I'm thinking of buying for my tx a Nick G kit from a friend of mine who is giving up the FT. I've been to see photos of the kit that is on my friend's tx and I found it strange that his kit that has titanium spring, aluminum piston but does not have red to drop, so I find it strange to know that the aluminum will collide directly in the bottom With steel. Can you explain why you do not have a red parachut head?
Can't wait to get mine tuned by Nick, he just asked me to wait a week before I pass it over to him. Oh I'm impatient 😒
Please let me know where I could buy one of these kits. I just bought a hw97 but I'm used to my 80 I've had since 1982 a beast with theoben zephure piston washer. Hard to find a replacement. Thanks in advance. Graham.
Awsume working mans review
I've got a working mans dickshunary too
Are the parachute seals or the oring seals longer lasting?
I guess from the price point the orings are cheaper to replace.
Out of all your 97s which kit do you prefer as I'm wanting to mess with mine
having watched a few of your videos detailing nicks work.. i have had to pester him about what can be done with my prosport. ill be blaming you totally :D
Anthony Price I’m having the same fucking problem I have a prosport too and just need a kit fitting
where can i order a nick gibney tuning kit for my tx200?
Hi, I recently bought a friend who gave up the FT a nick short stroke kit with aluminum piston and titanium spring. I already gave about 200 shots and I still find the cycle violent despite the speed being 767 fps with exact 8.4. I also found it strange that the piston did not have the red parachute. What feed back on this kit in the UK, I'm afraid I ended up damaging the scope. Thank you for your attention.
Could you show chronometer readings pre and post installation?
how are you getting away with resting on a rest without it kicking,,,,?
Neil, is the steel spring directly running against alloy piston skirt or is a sleeve used to prevent scoring of the inside of the piston ?
+Matt Winser - no sleeve at the minute. I will use it for a while and then strip and inspect it. It is well lubed up so I don't envisage it being a problem.
hi what sort of fps and ftlb is it making cheers
Great vid. Just wondering, could you not drill the existing piston to get it down to the same weight as Nick's? Or is it more to do with the o-ring seal?
+olly killick I don't know. Nick does a lot of experimentation to get the guns to shoot as sweet as they do. I just know it works :)
Thanks. I'll try and track him down!
another interesting video, looking forward to trying a Tx200 with nicks work inside, and choosing what tuning path to go down, we both happen to use the same range
I have shot a TX with one of Nick aluminium pistons fitted. Fast, snappy shot cycle. Almost no movement!
+shootingatdawn awesome, im looking forward to getting the internals finished,
cool videos too thanks for the uploads
Cheers mate - enjoy your guns :)
The difference between the 2 pistons amounts too what exactly, better muzzle velocity, distance etc
Top vid pal👍 did you get the transfer port altered ?? Thanks
+Jamie Parnell no -he likes to build his stuff using standard TP sizes so you can put the gun back to standard if you want.
Just wondering what it was you didn't like about the SFS tuned 97k as you have experience with lots of tuned 97k's? I'v put my wonky donkey tuned tx200hc up for sale its shot cycle is lovely
+loopoin I had a few shots with one gun at one of the springer bashes. It had cost the guy 700 quid I believe and the feel of the shot cycle wasn't a patch on any of my guns. Why would I want one? Maybe it was a bad one or something but until I shoot something that impresses me I am not going to want one. My next project is some new internals for my TX ;)
Does anybody know what scope is being used on this 97? Looks like under 40 objective?
It's good to see your comparisons of tuned hw97k's how come you don't have a sandwell field sports stage 2 hw97k?
+loopoin - I buy my guns and pay for the work myself. I already have 3 hw97s which probably stand me at 1500 quid. I have actually shot a Sandwell gun only once and I wasn't impressed so I don't reckon I will be investing in one.
How do i get this tuning done?
how about power readings?
Did your Nick Gibney kit improvements hold consistent over time?
Also is there a gas piston rifle that is quiet and accurate like the 97K?
You guys ever shoot these things or just tinker with em ...
Just got a hw97kt my first air rifle, was surprised how snappy it sounds especially after watching so many reviews on them and the rifle being so quiet. Is this just a case of the mics not being able to pic up the whole sound of the shot cycle?
What do you think of the Hw97
Hi just wondering what pellets are you using
+FamasFTW98 - H&N FT mate.
Good video, do you prefer Weihrauch's to Air Arms
I personally prefer Weihrauchs for no other reason than I prefer the feel. Future and size of them.
@@shootingatdawn lm just selling my Pro Sport today, l think it's the 97 l want, prob from McAvoy guns.
Please provide close ups and perhaps dimensions of Nicks piston if you would be so kind :) :)
I'm in the US and would like to modify my own HW97. It's not easy getting parts for them here.. so I would like to not mess up or have to do much experimenting on my own.
Well I am not planning on taking the gun apart any time soon, but when I do I will see what I can sort for you :)
Well I am not planning on taking the gun apart in the near future but I can tell you that the comp tube needs to be shortened to allow for the delrin piston ring to the rear of the piston. As for the piston itself I suspect it is standard length but made out of alloy rather than steel to allow for the weight saving.
what kind of scope do you recommend using on hw97k?
+Thomas Lunde - whatever suits you and is within your budget. I like the Mamba lite.
that thing looks like it wouldn't require something *air gun rated, e.g. hawke airmax and maybe the utg stuff? I don't know of any other examples, but I personally have an AIR MAX 3-9x40ao and other than the AO being a little heavy to turn, it's worked great
Pretty impressive Kit how can i contact mister Gibney I would like order one from him ....by the way great job sir i can see your passion for it ..Aloha
+Dario Bisogno Hello mate - I contact Nick via facebook. I will ask him for some different contact details and if he gives me an email address I will include it in the video description (if he permits me to of course)
+shootingatdawn very kind of you mate got it thanks a lot.
I contacted him. You can find him via either facebook or the airgunbbs forum
Great video you are sir a true air gun smith ,, I 'm here in the United States but I wanted to know do you all make those hybrids for the RWS 350 Magnums and if so how can I order one.
+Sid Bates - I wish I could do all the work myself but I don't. You need to contact Nick Gibney via the airgunbbs forum if you want to sample any of his work )
Hi
I would love this kit how can I purchase the NG kit ?
Contact Nick himself. Nicholasgibney1@gmail.com
hi..I do like that kit alot..I have a hw97 with a v mach kit fitted but it has a hell of a kick to it , it shoots bout 12 .30 .ft lbs. can I buy the same kit you have from nick.

Billy the kid can you fit kits ?
How does someone in the USA get the Nick Gibney hydrid piston kit ?
I would contact him directly. Nick Gibney - he is on a lot of the HW springer groups on facebook :)
Hi ! superb ! The gun seems to be perfect ! How can i get a kit like this for an Hw 97 k ? My hw 97k is kicking and jumping all over the place and it is hard to get even 2 pellets in the same hole ! I think it must be somthing wrong whit it ! Everyone speaks well of the HW 97 k but for real mine is not fun at all ! Want help !Thanks !
+Pinnkong - contact Nick G. He can be found on the Weihrauch groups on Facebook.
Can I still get the custom kit for HW77k
Contact Nick Gibney via the forums mate
looked almost pcp like, how does it Chrono
A steady 11.3 ft lbs with very little variance.
@@shootingatdawn what more could you ask for... myself torn between one of these or an LGU, or TX200 HC. decisions decisions. lol
@@shootingatdawn I went with the 97kt stl ..lovely looking rifle,think I'll stick with the strip clean and relube for now
@@lfcmarkeb7124 good choice i know there have been issues with lgu. That was a year ago and dont know if sorted now. Loss of pressure and bear traps falling off from brand new rifles. Hw97 all day long imo
From what I’ve read DONT USE RED RUBBER GREASE ON AN AIRGUN!! instead use red”n”tacky grease...cheers
How much price this gun i want ????
yoda! where have you been? we've been looking all over
Can you show the accuracy of the gun afterwards on all your videos as there is no point in modifying a gun and then it's inaccurate afterwards
+carol dennis working on it.
it does seem as though he would have mentioned that if it were the case
It looks no recoil
