AGT Vulcan 3 Sub 12 Tuning 

1000 shots. next level tuning. I think I would damage my eyesight from looking through the scope that long 🤩

Cracking job on the hammer ,you can clearly hear a difference and wearing headphones even better ,you know your stuff 🤘

Great video explaining the upgrade process in depth. You must have taken that rifle to bits quite a few times with all the experimentation.

What an awesome video i really enjoy watching you make your mods on your rifles .... Watching video like yours keep me motivated to keep doing this hobby sometimes i get bored even tho i shoot fac rifles that are very powerful i still have two rifles that i shoot only pellets at around 865 fps for a high shot count but geez 1100 shot from a sub 12 makes me want to lower my reg so i can get even more shots per fill thanks for sharing be safe buddy 💯

Some excellent modifications made to an already excellent air rifle. It really has gone to the next level with your tweaks and re-manufactured parts. Nicely done!

🤣🤣🤣 yes sir i think 800 shots will do . excellent job mate . what puts me off bull pups is that hammer noise which is odd because i also shoot a springer but the action is not right next to your ear . cracking gun out the box but the mods done bring it to another level 👌

When you get bored with it, just remember I need a rifle for FT 👍😂 great stuff as usual

It's quite funny because when I looked at one of these in my local shop, the loud action noise was the one reason I didn't end up walking out with it. If the factory ever decides to take your modifications on board, I would definitely have one. Another great video and thanks 😁👍

Sir, you are really genius, amazing craftsmanships, .. i really like that i was living close to you .. or maybe i will visit you when it happens to visit UK... Im from Kurdistan -Iraq

Really helping me understand the çomponents of a rifle and their purpose. Addictive viewing yet again thankyou.

Thank you for making the video, I haven't had to do any modification to my vulcan 3 , but great to see what is possible to improve the hammer noise, this is a fantastic rifle,

Excellent work, I wish I had half of your skills but I am improving thanks to watching your very well explained videos 👍👍

Another perfect example of your incredible & innovative engineering. This is absolutely brilliant gents. Looking forward to see it finished down the range 😁

Above and beyond as always , 👍

Excellent video as always. Everything so well thought through and the end result shows this👍

Really interesting this, fantastic work, with great Lathe work too. I recon that hammer is a real winner, big difference and a hell of alot better. Look forward to the next part. Very well do e sir!

Absolutely brilliant jake!! Awesome 👌

Great workmanship. Always look forward to your videos. well explained and thought out.

Excellent video mate, superb workmanship as usual

Top quality machine work and fantastic results as always!

Interesting video - really like the thought process on material choice and the explanations of expected benefits. Of course the results are great too and you can definitely hear the difference 🙂

One awesome job! Very nice done indeed.😊👍🏻

Cant wait for you guys to tune the Vixen.

Thanks once again Jeff for some invaluable info , you help and teach us so much about all brands of rifles, Thank you, Cheers 😁👌👌👌👍👍👍👍👍👍👍👍👍

Excellent work again. I would concentrate on making sure a lightest possible hammer is free floating, even with 0.5mm gap, to save air/make more efficient. With free floating hammer I would have guessed 80bar being most efficient. The real efficiency killer that I see is the volume of expansion between valve face and pellet. If only the design had been made with eccentric valve placed nearer the barrel.

You should open up a tuning shop you would do well I believe, I for one would be a customer

Top Quality 👍🏽 about time I got one 👍🏽😎👍🏽

As ever you are a amazing thanks for sharing

You are The Master. Amazing videos. Regards, Baz.

Great video, as always, Jeff. 👍

High ending modified. Good work on Airgunolgy

Is there nothing you can’t do. Excellent video.

Great content 👌

Muito bom!!! Parabéns!!!

to me you are a magician

You dont need much to heat treat simple steels like O1 toolsteel. Decent propane torch, couple fire bricks and some canola oil should do the trick, temper in a cheap toaster oven and thats about all you need. Yes a dedicated pid controlled electric heat treating is easier but not needed. I have built one for heat treating the knives i make but did heat treating with a propane torch and a couple fire bricks for a long time.

Hi sir, you can add regulator gauge pressure on this airgun? If you can, please make a video. Thank you

Nice👍🏻👍🏻

Nice sir...and thks🙏

Once again love watching your videos.. fantastic job done, your skills are amazing..id love to own one of your rifles that you have worked on..I'm already subscribed and as always looks forward to the next video.. thanks again..

You can spend a whole month on one charge, you have thought about automatics for a little fun, greetings

Meu amigo que loucura..espero que leia meu comentário..eu fiz um video ..mostrando a reguladora..mas queria muito fazer um martelo desses

nice

Hello. Great work ! Do you think that a slingshot hammer would be useful ? In theory Is not difficult to build, taking inspiration from the uragan 2 system and using an harder and shorter spring. Thank you very much.

Hi, are you going to sell the hammer upgrade with the peake, excuse the spelling, for FAC spec

1000 shots?? You not aiming low on the prospective shot count, eh?😊

Any chance you'll sell any of those modifications?

? Is this method effecfive on FAC rifles

Hi, Did you bother to polish the barrel, I know you have mentioned in the past that you polish almost all of your barrels.

Very poor accuracy for such a expensive pcp..

Awesome content as usual Sir.

Only got your word for that
