Craig VanMeter I have very few air powered guns I can leave alone. My Benjamin Bulldog is getting ready to go under the knife this winter. Isn't it great to be an American lol

Glad you got something out of it!

what are you using as substitute arrows? I've read 2016 aluminum air shafts so do the trick... have yet to try it.

@@Americanson24 They are the standard arrows, I just have heavier field tips to match the broadheads that I will be using. Not really an archer so I didn't think to separate out the shaft and point weights.

It could be, but money was backed all the way out. It has a sort of curious plenum space in the valve body that could easily have a plastic plug inserted to reduce plenum space and in turn reduce velocity. Then the spring could be adjusted to fine tune it. That's what they did to the T4E co2 shotgun I have, only without any spring adjustment Never thought of the UK market

@@kidpellet6544 Unfortunately here in the UK we always get the watered down versions of any PCP air rifles, break barrels, or air bows like the javelin or Benjamin air bow which have the power lowered compared to the us versions..

I'm gonna check that out. I just got a Benjamin Armada so I've been playing with that instead. I'll get around to taking the valve apart this weekend for sure

Once I insert the c02 how long can I store the gun with it still inside?

@@RawDogTV For a while and it's a highly debatable subject as to how long. Air, can be in there indefinitely and it is good to store pump guns and PCP's etc. with some air in them (keeps the seals good), but CO2 is different. You can certainly go a few weeks or a month or even more, but they do slowly leak out over time. Some people who are against it, also claim it's acidic and over time can damage things, like seals. CO2 is carbonic acid, so I suppose there could be something to it. Probably not good to do really long term like many months. I haven't researched the subject in depth truth be told (so many other things to do, lol). There's a lot of myths and claims about airguns, some true, some not. GTA airgun forums (Gateway to airguns) is a great place to get legit info. People who have been airgunning for many years and know their stuff and one of them did a list of that, myths they believed about airguns (and some of those myths are on GTA forums to this day). So even there, you gotta watch what you believe. But I am sure if anyone knows the legit answers, it's them, they are smart folks and it's probably a question they have good answers to. Unlike some KZfaq videos. Much as I like Mike from Replica Airguns, he did a video on that and said "a week?" and was not too sure sound of himself, lol. Mine's already been in my pistol for two and I ain't worried, lol. I shoot it one shot a day to see and it still has plenty of power and that's just a little 12 grammer. So whatever it loses over time, is minimal (as long as your seals are good). For this gun however?! There's a neat device Umarex sells, that only works with one other gun and the AirJavelin called the CO2 Saver (costs $20) and it screws into the gun and the CO2 cart. screws into it. Making your 88 or 90 gram pricey CO2 cart. removable! Without losing all the CO2. A thing unique to their guns. They wanted people to have the ability to transfer carts. from one gun to another gun possible/convenient without losing all the CO2. Nice! It also serves a second function though as a CO2 storage device. So, if the claim about CO2 not being not good to be left in airguns for a long time is true or false, with this, you don't have to worry about it and leave it in the gun at all, lol. There's another cool option for these. A $50 part that converts 12-gram CO2 carts. to fire in this gun. It's a machined metal canister, that houses 2 (or 3?) 12 gram CO2 carts and is also made by Umarex. Saw a guy test them and they give you about 10-12 shots. Not bad considering a full-size one gives you maybe 30-40. So if you only want to do a short, cheap shooting session without any full-size canister hassle and storing it and worrying about it slowly leaking out over time or something like the guns themselves do? Then that, is the perfect alternative. Filler 'er up, shoot 10-12 shots and empty, no leftovers. The flexibility of this thing is very cool. They were really thinking with the accessories on those. Really smart accessories, not stupid. I immediately bought the CO2 Saver, cause it was cheap and logical. Those big canisters aren't cheap and the ability to save them, outside the gun is not only convenient, but better for the law and transportation. Depending on where you live and storage/transportation laws, that could be really useful. Like a magazine, not only has to be empty, but also not in the gun in storage/transportation either. There could be laws around transporting/storing something like this, in a "ready to fire" state as well. But not with this, the ability to fire is not in the gun, the CO2, so zero issues. The other option, when worked out math wise (someone on KZfaq did, lol) loading it with 2 or 3 12 gram CO2's worked out "slightly" cheaper per shot overall too than the big ones. Not much, 2-4 cents a shot maybe I think? But cheaper and ideal for doing just a few shots and could certainly be worth it if it fits your needs. You don't "have to" fire the big ones at all if you don't want. With that part you could shoot 12 gram carts exclusively. That canister converter is worth $50, it looks equally solid to my CO2 Saver and a quality piece worth it's price. And it may slowly pay for itself with those pennies saved on shots, hehe.

@@MrBilld75 I can't tell you how much i appreciated this essay.

@@jbignJesus Cool!. Glad it helped.

I'm sure you can get it pretty low by just changing the hammer spring with a lighter one. Pretty easy to get to and you should be able to find one at a hardware store or big box store. If not theres an online springstore.com that should be able to help. Just get a couple different ones to try. The more complicated way but probably would have more consistency is to put a an HPA regulated bottle on it and turn the regulator down. I've not shot a fish with mine yet but 300 fps seems a little hot unless the fish is pretty big

I did and it made no difference in velocity. At least not with mine

Not sure what they intended them for but 12 gram co2 for right in there

@@kidpellet6544 ah ha! That's funny!😅 I did see a guy using an adapter and 12g's, getting about 3 shots/12g. Good for backups I guess 😅 thanks for the informative video. subscribed 😎🤘

I've had 1100 psi in mine with not much change in velocity at all. Possibly needs a little stiffer spring. Havent had much time to mess with it for a while. Ive heard the new Air Javelin Pro is regulated to 1500 psi but dont know if it has the same valve body. If you look inside yours you'll see a cast aluminum valve body with caps held in place by cross pins. I'm a little afraid of the valve body mostly because its cast aluminum and a little because of the pins. If it was machined from billet aluminum I wouldn't be that afraid. I really only converted mine to get away from the co2 and I already had the Gauntlet to rob the regulated bottle from. If you look through the videos you'll see the inside and the valve body. I've had mine completely apart figuring I could find some sort of air restrictions I could open up. Every passage is about the size of the barrel itself so there really wasn't much to open up. I think the answer is a little more weight in the hammer and stiffer spring, maybe. It's a relatively short barrel to get that much weight moving. If it were a pellet gun and you were trying to get a projectile moving faster you would get further with more air pressure than anything else. If I could confirm the AJ Pro has the same valve body I would bump mine up to 1500 psi also. I'm going to get one when I can just to tear into lol. I also have an Air Javelin FB group you can share your ideas in if you want

Yes but unfortunately not much

I suspect there is something limiting the air flow. I have ideas but will need to take the valve assembly apart to confirm. About the Allen wrench size, I'll check when I get home. It is standard though, not metric

@@kidpellet6544 Ok sounds good, thanks!

Thanks for the interest. I dont really remember how many shots I got with the dual co2 from my Fusion 2 but it wasn't nearly as many as the 88 gram. I converted mine to PCP and I think I got around 30 shots with a 13 ci Gauntlet bottle. Now it has a 4500 psi carbon fiber bottle on it but I haven't done a shot count with it yet. Fun little arrow guns. Trying to get a rat with mine this weekend

@@kidpellet6544 happy hunting brother, happy hunting!

I hope you er...rat...a...cate...them!

If you have a regulated tank and hose you just need to drill and tap your used 88/90 gram co2 for a fill nipple and shoot tethered. If you want a bottled setup you'll need a regulated bottle, a bottle adapter and yet another adapter so the bottle adapter will fit the gun. Search these videos and you'll see them. Just a heads up,if you dont already have some of this stuff like the regulated bottle, it costs about the same as the Air Javelin did. My adapter is $10 + shipping Archers bottle adapter is luke $46 + shipping. And the regulated bottles are like $50 to $100 on ebay. I only did mine because I had everything but the adapter that I make. If you buy it all your going to have roughly $300 into it and the Air Sabre is like $400. So it's great if you just like doing stuff like this or really want to save a few bucks its probably not that cost effective lol.

It could be replaced but I dont think you could put any other type of barrel on it easily

I would try Umarex USA www.umarexusa.com/ Call them and see if they can help

@@kidpellet6544 Idid and i will have to return it and then they refer me back to Canada but i bought it in the USA , is the no place where i can just order the part ? thanks

@@ratamrautenbach2957 sorry but Umarex USA is the only place I know. You could maybe get a long machine screw to get you by

If you mean the little round part with the silver setscrew in it then making it shorter would lower power

Yes I'll chronograph it a couple of more times to see if it does much. The little part that slides, didn't slide well at all. The set screw pushed it forward but it wouldn't slide back. Had to work on it a little so it slides free. Just the nature of plastic parts I suppose

@@kidpellet6544 a little grease/ lube might help.

@@larrydickens3437 I think Silicon grease would be ideal as it has no ill effect with plastics.

It's an adjustment for the hammer spring

Sorry but I can not translate text

Hunter 6122 check out the video of me shooting the converted Air Javelin with the stock bottle from my .177 Gauntlet. I have a few of the adapters made up already but you have to be able to drill two holes to mount the drop block from Archer airguns. Message me on FB. Also check out my FB group for Air Javelins. The link is in here somewhere

I dont actually remember man. It's kinda hard to tell it's even turng the adjuster. It goes in it an angle and you turn it counterclockwise to increase the spring pressure. The rear of the stock comes off really easy and you can take it apart and see the adjuster to check for size. I think someone else may have posted the size either in these comments or in the FB group comments

I got a few crossbow bolts with 100 grain field tips. They shoot noticeably slower for sure so you would have a little more drop. As long as you know where to aim for the distances you should be fine out to 30 yards or so. I want to say it shot them at around 270 fps but not positive. Somewhere around that velocity if it's much further than 30 yards the game can hear the shot before the bolt gets to them.
