    Just not working on my end- asks me to log in, but I don't have an account w/warner cable.

    The only BB gun like the RR I know of besides the Cowboy is this one. I asked about it on another forum, maybe 6 months ago IIRC, no one had any real info. FWIW there's also an Annie Oakley version of that same BB gun.

    Yes, that's the one I was trying to display.
    They also have a large loop model called the John Wayne.

    Their distributed by Air Venturi through Pyramid Air.

    Hi!
    I'm a newbie here and find this http://shop.ehobbyasia.com/ktw-winchester-m1873-carbine-spring-rifle.html#.WVL_IS5v9J8 like RR.
    I buy a RR here in Brazil and found you searching about custom.
    I have some questions: its possible to use nitro-piston?
    Its possible to change to another caliber? 4.5mm to 6mm pellet?

    Hii CC and welcome aboard!

    That's a cool looking gun you linked to. It's airsoft and I do not know much about them.

    The way the power plant of a repeating Daisy BB gun like the Red Ryder is designed, using a nitro-piston would be difficult. A way would be needed to attach an air tube to the front of the piston in order for it to work as a repeater. Maybe making a BB gun that was a single shot like the model 499 might be more practical. But as sure as I say that and someone with skills and imagination beyond my own will make one!

    The biggest problem with using a Daisy BB gun for airsoft would be the small size of the compression chamber. But again- my knowledge of airsoft is very limited. And if I've learned anything while modifying these BB guns, it is that anything is possible!!

    Thank you só much for answer me!
    As a novice, i will try my best to learn more about all of the knowledge you and others as my seniors write here and other places.
    I will read again all the posts here.
    In Brasil, do tests like yours are dificult because the import taxes and products prices but i will try.
    Sorry for my english.
    I am good to read because i am a Programmer but to write im a disaster hehehehehe.

    I can tell you that your English is a million times better than my Portuguese! Feel free to ask anything here. There are many knowledgeable people who will help.

    Welcome! I really like the linked gun. I have a soft spot for the lever action guns. I only have one airsoft, so don't know a lot about them.

    Although I am one to attempt many modifications on the daisy guns, I tend to be with cobalt on the difficulty of adapting a nitro piston, or changing caliber.

    Feeding the airsoft "bb's" seems to require a spring action of some nature, which the 1938b platform is not conducive to.

    Cocking a nitro piston would also seem difficult. Not sure how that would work. Though I don't have any of those pieces to study.

    My airsoft is a Maruzen Type 96. The air chamber is much larger the the 1938B. It seems to need lots of air to move the pellet. It has MV around 400-415.

    So....I don't wish to discourage innovation! Let us know what you come up with.

    IMG_0465.JPG IMG_0466.JPG IMG_0467.JPG IMG_0468.JPG IMG_0469.JPG IMG_0470.JPG Bit of an air tube research update. We have very successfully drilled stock air tubes to 1/8" ID. Started milling the port bigger to test for maximum mv. Then my brother got called away on a consulting job out of state. So... all the parts are locked up in his shop. Hopefully he'll be back so I can get the parts to do some testing! A few pics.

    I now have qty 2 more 499 barrels in my hands. More research and testing.

    I also ordered 3 RR shot tube assy. 2 of them are seamed. 1 seamless. I even specifically asked them to only send the seamless. I have had a couple of phone conversations with them. They are trying to understand what I am talking about. Will be sending pictures to them this am.

    Also ordered another Aim brand picatinny rail. This one is the 0.31 thick version. It is to spec. I have another idea how to mount it. Stay tuned.

    I'm also waiting on delivery of a Bug Buster scope. Hoping it might help me with a bit of accuracy testing on the 499 hybrid.

    Lots to do.

    The 1/8" ID air tubes look killer! You guys are on a roll!!

    Been too long since I visited, so thought I'd stop in and say hello. I hope everyone has been doing well and are still enjoying their Daisys! I've not had time to devote to any Daisy projects but I'm hoping to rectify that, now that things here have calmed down some (house painting inside and out, roofs and gutters on two houses along with other assorted chores getting in the way).

    Found an interesting thread on gas rams. IIRC, this might have been brought up earlier. Anyway, it turns out there are rams that have the OD and stroke length that is compatible with Daisy lever BB guns like our Red Ryders, Bucks, etc. The one I looked at is 19mm OD with a 2" stroke. I'm not sure how the specs for the gas ram energy relates to our springs, but I'll be looking into this in more detail. Just thought it would be neat to build a gas ram RR!

    Cobalt, Most interesting. If anyone can figure out how to cram a gas ram into a Daisy, it will be this bunch. I will be keeping an eye on this. Still love the 499 w/ R.R. spring! Chris

    Hinz57 and his brother could pull off the gas ram, I'd bet. Maybe if I send them a ram... mwink.gif

    Just found this. Have not read all 18 pages, but I don't suppose anyone has asked, "Where can you get square cross-section spring stock?" I would love to wind a spring for my old Daisy out of that!

    Interested in hearing your results if you do this. Some thoughts that may (or may not :D) be of some use is it's pretty easy to over spring these Daisy lever action BB guns, so I'd say it will be a good idea to sneak up on the final spring rate unless you're going to use a beefed up plunger tube.I've found the factory plunger tube begins to deflect (causing drag on the spring ID) at rates around 22-24 lbs./in. give or take. But hinz57 has found that adjusting the stock configuration spring anchor so that it holds the spring squarely to the plunger adds capacity before deflection becomes an issue. So that spring rate isn't written in stone by any means- but securing the spring squarely IS important by all indications, especially once spring rates climb. The new production plastic trigger 'module' will also begin to strain at higher spring rates. Using a gun w/the earlier style 1-piece stamped steel trigger can give some added leeway.

    Good luck and keep us posted!

    If a BB measures .177, and 1/8" equals .125, what did I miss? Are Hinz and Brother producing sub-bore Red Ryders? I'm not sure I hate the idea.

    Ooops..... OK, I get it now. Air tubes, not barrels. Derp.

    Haha! The Daisy IS loaded with 'tubes' of one sort or another; air, shot and plunger tubes- but it's extra easy to mix air tubes and shot tubes!

    I'm a Doxie fan myself. I have to ask, in your avatar is that the start of a canine birthday party?
