Thanks Archer!. That is great to know. Sometimes its hard to scale ones own ability to difficulty ratings but I guess that makes sense without instructions vs having them. I look forward to replacing these parts.
@@simenolsen4179 if you bought yours in canada im sure youve noticed it could have a little more velocity,and yes it does have a bit more snap to it.if you do the valve mod it shoots even faster but it will only pierce one of the co2 cartridges and youll only have about 40 shots before you have to change.i dunno,they are all pretty easy to do and the extra snap is nice.
Great co2 rifles for the money wood stock and all metal' My .22 topped @ 18fpe @70° 20fpe @80° .177 14fpe @70° Both shoot very well for the grade barrel out to fifty yds' I use arrow inserts and empty 22mag cases to make transfer ports' also put a fixed piercing pin on the front of valve to do away with the shoot pin'
Th78d is the same gun just with a thumbhole stock. Thank you for the video, will be alot of help if i decide to buy this airgun, which is looking pretty likely. :) What are you shipping rates like for the uk? I love the look of the multishot mags ;)
the first thing you do while replacing the seals in your qb78 rifle is to install new and improved seals or after market seals or you will need to replace them again in 6 months i know because i bought a new qb78 rifle and with less than a hundred shots and three months the seals blue out and i had to send it off for repairs
@ArcherAirguns actually for someone who you would think should know about airguns your wrong the 1.77 would see a bigger power increase, and the bigger the pellet the slower the increase would be
Ironcially I can't seem to find any of m tools at the moment. A solid chopstick should work? I have some that are no longer used as chopsticks themselves so I wouldn't mind if they snapped. (If it snaps I know not to use tem next time for something similar. : ) )
@ArcherAirguns Thanks very much for that Just a last quick one, after replacing the breach seal, does it increase Co2 consumption much? or does the Hammer determine how much Co2 comes through? Bit new on the co2 scene
Well informative video Going to have a pop at this soon, whilst I am here, you don't happen to know if you can disassemble the bolt mechanism? Just mine is has a really roughing cocking cycle and want to polish it
thanks 4 upload great help any chance you could make 1 ov removing the valve and taking and replacing with new as not many videos out with this information thanks again
The video does not make it seem to hard to replace the seals and o-rings. However, on your site you have it stated as 5 star difficulty. How difficult exactly is it? As the video it seems more over dealing with a lot of small details (as it seems less difficult compared to more in-depth changes). So wanted to know what your recommendations for doing this upgrade is.
Hey steve. I love this gun. However still have an issue here. Instead of this seal upgrade. I almost want to mill a 1/16 inch flat off the breach ,where the seal meets and tig weld a small peice of 1/8 long by 3/16 i.d., steal tubing back so i only need to use a less restrictive standard oring on the main tube. I know this isn't a homeowner fix, but whats better for the longrun? This seal used in the upgrade seems like its got a long distance to hold the gas in for a permenant fix?
Quick question about removing the safety trigger. If we don't have a dowel or the brass. What can be used instead? Want to double check as so I don't use something that may end up damaging it.
the QB78 looks really nice, im a newbie to hunting an dont want to spend loads of money on an air rifle, but want enough power and accuracy for hunting (largest game possibly rabbit cos i live in the UK) is the QB78 good for me?
Really stupid question here but I'm just wondering does a projectile from say a sniper rifle speed up over a certain distance before slowing down. E.g. if something was shot at 200m would it have more stopping power than shooting something from 1-2m?
@R Hebner ha I remember asking this question 8 years ago. Thanks for the answer Hebner! I can see when I wrote it I asked the question incorrectly when I said "speed up over a certain distance". What I meant to ask was specifically what the acceleration was of a projectile fired from a rifle (obviously changes based on various factors some of which you've mentioned). Little google search in 2020 seems to indicate acceleration applies until it leaves the end of barrel.
@MultiSniper70 ha you think i ment you lolz dont flatter your self i was referring to archer airguns being the "godfather" i didnt realise the video was from them archer airguns know everything there is to know about xs qb they wrote the book and i cant believe i questioned them, no hard feelins a?
Where can i buy the replacement breech seal in Canada? Would I find anything that would work as the seals at a hardware store? I hope you can help, thanks!
Iv got a ? My qbs 78 was working fine and today i went to shoot it and the pellet bearly comes out the barrel is this the breech seal i need to change the gun is only 2months old
if you have an fac can you order an airgun from any company with an already upgraded seal? i heard its possible to replace a .22 strut with a .177 version to improve power is that true or safe?
whats a tank block kit do for the qb79? if i buy the gun i want to be able to use a 9 oz c02 tank but i can't find any that are 2 inches or smaller ...is changing the breech hard to do because i could buy the bigger breech mayb but that is kind of expensive...if anyone knows were i can buy a 9 oz. paintball tank thats is 2 inches or smaller plaz reply!
Try Ebay and look for air gun parts in England, Canada is still selling muskets along with glass marbles. if you have a valid FAC and taken a firearms course so they know you won't shoot yourself in the head while cleaning the barrel.
The best video I have seen for this. Thank you.
Thanks Archer!. That is great to know. Sometimes its hard to scale ones own ability to difficulty ratings but I guess that makes sense without instructions vs having them. I look forward to replacing these parts.
Thanks for the cool video! Crosman, Beeman, Daisy and similar air rifles are a hobby I am bringing back to life now and really enjoying.
Works great. Bought and installed this kit and it works great! Highly recommend this...
I did this mod,and yes,it does work.i saw a bit of a bump in velocity with mine
Will the rifle be stronger or what ? :)

If you're in Canada, forget Archer, they don't sell, ship or deal with anyone outside of the USA
Makes sense to change the hammer spring the same time.
I'm looking forward to seeing it,it looks like a cool gun in general and thinking about purchasing it in the future.
@hagmouse you can get 28.6642 foot lbs at 950 fps with a 14.3 grain pellet using only a 12 gm co2 bottle for power in a 22xx series or QB plat form ,,
@ArcherAirguns ok, thanks. By the way you guys make amazing quality air guns.
Great co2 rifles for the money wood stock and all metal'
My .22 topped @ 18fpe @70° 20fpe @80°
.177 14fpe @70°
Both shoot very well for the grade barrel out to fifty yds'
I use arrow inserts and empty 22mag cases to make transfer ports' also put a fixed piercing pin on the front of valve to do away with the shoot pin'
Ps: manual mags are available form Rowanengineering and BB multishots from qbmultimags
@MultiSniper70 cant even believe i even attempted to question the "godfather"
ok, thanks for the reply, i will try contacting the local hunters club first then
thats the new edition of the qb78 with the longer gas cap.
Th78d is the same gun just with a thumbhole stock.
Thank you for the video, will be alot of help if i decide to buy this airgun, which is looking pretty likely. :)

awesome review ,thanks
(On video, part 2:35) Why can't we tighten the Phillips breach screw that compresses the new seal?
Good Video Thanks:)
@ArcherAirguns actually for someone who you would think should know about airguns your wrong the 1.77 would see a bigger power increase, and the bigger the pellet the slower the increase would be
@bigredonedday I bought it from a guy called 'Sniper' on the Canadian airgun Forum.
Cheers!

@ArcherAirguns
Thanks very much for that
Just a last quick one, after replacing the breach seal, does it increase Co2 consumption much? or does the Hammer determine how much Co2 comes through?
Bit new on the co2 scene
i seem to have air comming out of the breach and the bottle top is this how can i solve it.
@bigredonedday No problem! Good luck.
Hi, very helpful video. Do you have to replace the barrel seals Everytime the barrel has been removed or was that part of a tuneup. Thanks.
Bazmati2020 not if the seal is still good
Well informative video
Going to have a pop at this soon, whilst I am here, you don't happen to know if you can disassemble the bolt mechanism? Just mine is has a really roughing cocking cycle and want to polish it
Love it
По сравнению с нашими мастерами художественно свиста, вы как дети малые.
question why dont you do this at the factory when your bilding them ?? Why dont we just buy an other gun like discovery .
Colin Long They don't build them, they sell, upgrade and mod them.
thanks 4 upload great help any chance you could make 1 ov removing the valve and taking and replacing with new as not many videos out with this information thanks again
Seems like a cool concept,and i'm not trying to make a rude comment but...why not just already include the new seal in an "improved model" of the gun?
All good stuff, but you still don't send to the UK, Why Steven, Why?
Problem with the QB78 is the valve port is not lined up with the seal,
@bigredonedday He is a retailer...I highly reccomend him, great service and great prices. Just join the forum and PM him.
Cheers
i would love to buy parts from archerairguns but sadly they don't sell to canada
_Why are you trying to destroy my dreams?_
Agh, damn, all I was wanting to do was to still a screw driver in my hand.
Makes me angree this kind a nannying

How come it doesnt have a valve port, like the crosman 2240?
Interesting fix!
Does ArcherAirguns ship to canada?
If not is this seal the same as a 1377/1322?
_[This being a Crosman 160/167]_
Anyone know if the qb78 and qb79 breeches are the same?
Hey steve. I love this gun. However still have an issue here. Instead of this seal upgrade.

@DannE0012 You are doing it wrong if you cannot get within 100 yards lol anyways go for a spring piston pellet rifle if you want that range
SO COULD I DO THIS TO THE TH78D,, PRETTY SURE THERE THE SAME BT THE TH HAS THUMBHOLE STOCK,, PLS REPLY
Quick question about removing the safety trigger. If we don't have a dowel or the brass. What can be used instead? Want to double check as so I don't use something that may end up damaging it.
Because its a Crossman...

Why is my breach port so small compared to yours in the video the hole in the seal is like 3/16 and mine is like 1/16
Can I make Teflon Plastic seals?

were is your company based ?
Where can i buy the replacement breech seal in Canada? Would I find anything that would work as the seals at a hardware store? I hope you can help, thanks!
Where can I find some decent breech seals for the QB78d? Bought on ebay but once installed (thanks to your vid) still had the air leak..
@VisitingBoss
yes but you lower the acrucy
doors swing bothways mate do a test 22 vs 177
22 is the best 177 is not so good on acrucy
Jonathan Oxlade lol my 177 I can shoot the same spot every time not prob ??
Iv got a ? My qbs 78 was working fine and today i went to shoot it and the pellet bearly comes out the barrel is this the breech seal i need to change the gun is only 2months old
would this make it go past 12ft/lbs coz thats the legal limit for air rifles in england im really thinkin of getting this upgrade cheers
if you have an fac can you order an airgun from any company with an already upgraded seal? i heard its possible to replace a .22 strut with a .177 version to improve power is that true or safe?
why not just ship the gun with the more powerful seal?
Because shit head archer has to make money. Glad here in the uk we got rid of the Twat. You've got him now.
@ArcherAirguns how many psi is the bulk fill kit 1000psi 2000psi? I have no clue.
is it the same for the .22 and what power gains could be expected on the .22?
Is the TH78D the same as the QB78 just with a different stock ?
whats a tank block kit do for the qb79? if i buy the gun i want to be able to use a 9 oz c02 tank but i can't find any that are 2 inches or smaller ...is changing the breech hard to do because i could buy the bigger breech mayb but that is kind of expensive...if anyone knows were i can buy a 9 oz. paintball tank thats is 2 inches or smaller plaz reply!
does this work whith many guns aw just this 1 just i have an s510 and i reely want it tuning up but dont no how:(
does these seals work with the crosman 2260? or the 1760?
Dont know if dieseling would be good for this one😂
Is it the same for the xs 78? I just want to be 100% sure
Fuck that I wouldn't be able to put it back together
Which company?
can i get this seal in canada?
Try Ebay and look for air gun parts in England, Canada is still selling muskets along with glass marbles. if you have a valid FAC and taken a firearms course so they know you won't shoot yourself in the head while cleaning the barrel.
