Pack/Bicycle Rifle Project Options

Don't remember if it was here or over on Rim Fire Central that someone "made" a bicycle rifle from an NAA mini revolver. Barrel certainly more than 16 inches and a skeleton stock were added. Looked neat as all get out.

I have yet to be able to remove the butt plate from our chipmunk. Heating with a hair drier and keeping it hot for an age seemed to do nothing and I decided not to destroy the thing getting it off. I wanted to go the other way, and lengthen the existing stock at least an inch and a half to give us adults the ability to use it better.

That Cricket "Jackal" home built has real possibilities....... something that might fit in a bit of PVC pipe with screw caps (like a fishing rod carrier but short enough to go under the truck's back seat)) un assembled.

Any opinions on caliber; 22LR, 22mag, or 17HMR?

I have zero experience with .17 HMR. I have "hands on" experience with the other two.

The trouble with the .22 WMR in a revolving cylinder will be the ear splitting blast coming out of that cylinder gap. The long barrel won't mute that.

The .22LR would probably be my pick due to shooting everything from Super Colibris, CCI Quiets, and up. CCI Quiets truly need no hearing protection out a non-revolver rifle barrel.

For a packing camp gun, I personally would want the gun I wouldn't have to put in ear plugs for.

Just my opinion of course. :D
 
Another thought about .22 WMR is how a small change in hold of the firearm makes the muzzle rise (or not rise) ever so slightly causing shots to string up. I don't experience this with any other caliber. Perhaps .17 HMR is the same?

I mention this because if I'm not in the .22 WMR mindset when pulling the trigger on a .22 WMR rifle or my Ruger Single Six (pictured earlier) muzzle rise will cause shots to go up about an inch at 25 yards. I don't have to think like that with .22 LR or centerfire rifles.

However, I really enjoy the challenge of shooting .22 WMR well which makes practicing worthwhile and everything I just wrote kind of moot. :D
 
I got a Savage 24 410/22 that I am thinking about. How about a smokeless rated topbreak pistol like an H&R Premier 32 S&W short.
 
Attached are some rough sketches of my ideas so far...

I like the layout of the NAA conversion the most so far (I have a flexible neck :p), though there's no reason a similar sliding stock wouldn't work for the Chiappa (just more work). Actually, I could bow the stock upward a bit, so when slid back the comb drops down more comfortably.

The trouble with the Chiappa's factory folding setup is that they broke the action down rather than up; great for accommodating optics/rails, but not so much for clearing the trigger guard. Short of folding trigger/takedown lever, or totally new side-folding stock, there's not much of a solution. So the shortening action would have to take place at the stock and not the frame. The pictured mod has the stock twist on single wire 180deg to move in closer to the barrel.

I also found about the NAA Ranger breaktop, which sounds positively awesome, well, were it not over 700$ and not made anymore.

To be honest, the prospect of cylinder flash/blast being obnoxious hadn't occurred to me (I always wear ear pro, and would bring some foam plugs to shoot this thing for sure), but judging by the NAA rifle build over on Rimfire Central, the cylinder gap can be closed up a bit when the new barrel is installed. I suppose that if you actually trued up the cylinder face to the barrel, you could get them crazy close without effecting reliability for the dozen or so shots you'd ever put down range without any cleaning. I also wonder if a 17HMR mini-revolver would blow the cylinder forward and tend to 'seal' itself, Nagant-style, but without the trigger force?

I've looked into older break-top, rolling block, and falling block setups, and a recurring theme is present; wow, are those things heavy and expensive. They generally appear rated for something like 223! :eek: I think that a lighter falling or tilting block (Farquharson, Martini, or Peabody) could definitely be made, but I think it'd be a tremendous amount of work to complete.

Another alternative is the Jaco Western action, which is functional, but that's about the extent of its skills :D

If I decide to go to that much effort (making every single part) I think I would just go with a miniature tilting/falling block action, but built the same way using laminated plates. Probably more aluminum, though ;)

"How about a smokeless rated topbreak pistol like an H&R Premier 32 S&W short."
I much prefer top break actions, but they also tend to be really big/heavy for what they do. Now, if there was a way (and I can't think of any reason why not) to make a Little-Badger sized break open frame with a 5 shot NAA-size cylinder, I think it'd be a winner, but there's not one available to my knowledge. Heck, I bet you don't even need a topstrap for a 22LR revolver, just make a slightly beefier latch at the hinge below the barrel.

Natman, I've been drooling over Teddy's NAA conversion for a while; I've actually been torn between the Chiappa and NAA for like six months, now. It's just recently that I've decided to actually get on the project :cool:

There's a really funny picture of the rifle's prey, a squirrel, not quite dwarfing the little rifle (squirrel's like half the length of the gun, and looks heavier)

I had bought two Cz scout camp combo rifles. One was a combo 22&410 all metal, the second was 22 hornet and 410 all metal in brushed stainless steel. Their concept is great break action o/u selective use hinged so it folded in half. The metal stock had a compartment that contained about 5-10 cartridges. The trigger was ackward as you had to squeeze toward the stock. Accuracy was bad and was happy to sell. Had similar accuracy with ar7.
 
I once made a cheek rifle out of a broken folding stock and a 10-22. It was ok but I liked it better as a 10-22. Your cheek can take the recoil of a 22lr. These are great for shooting out of the car window where permitted..
 
The direction this thread is taking makes me think that you're looking more for an appealing project than the quickest way to get a compact pack rifle. And that's more than fine as long as you realize that you're missing out on some easy and quick options along the way.

The one I'd avoid is trying to adapt any sort of top break revolver action. The added leverage of a longer barrel and attached shoulder stock would be much too likely to bend or break the hinge and catch. Especially since the top break guns tended to be cheaply made from softer and cheaper metal selected more for the ease of machining than for durability.

One advantage of that NAA mini revolver with the sliding wire stock is that you're putting all the potential bending loads into the shoulder stock mounting block located at the frame end of the barrel. The frame, cylinder and action is thus isolated from much of the possible bending damage that could occur during an accidental trip and fall onto the gun. And that's a good design feature.
 
I've used this off an on as a pack rifle over the last three decades. Basically a stripped down Ar7 with a tele stock w/pistol grip removed. Taken a few squirels and such with it. Ar7 reliability is all about the mags. This is very light and compact when taken apart.


Ranger bands i.e, pieces of bicycle inner tube hold it together w/mags when taken apart

You caught me, BCRider, I love me a good project :D. The Badger is the readymade solution I'd go for.

That's a cool semi alternative, Mac66, you see even fewer semiauto ligtweights than single shots

There are lots of the Stevens Tip Up pistols for sale. A new barrel a new stock and there you go.
 
First gun I bought in 1972, TC Contender, 22LR 10" bull barrel, 2x7 TC Scope. On a rest, it's very accurate.
 
^^

Nothing is so collectable that a discerning person can't continue to use it. Plenty of English double rifles still go to Africa, plenty of Parker shotguns still take grouse, and there's no reason not to pack a Game Getter for keeping the pot full.

I'm an AR-7 fan though myself, and the minimalist tube-stock as shown above is a pretty good choice.

If one could use a little more power, seven shots and no cylinder gap blast a Russian Nagant could be used. A straight piece of light aluminum tubing could be epoxied over the barrel after removing the sight. Lose the grips and bolt on a butt stock. 1000 fps with a 90-100 grain boolit ought to be easy.
 
Beretta makes a NEOS carbine kit but they are evidently hard to find and expensive used. Plus, while I personally think they are awesome, I don't think they really fit the pack rifle ideal the OP is shooting for. Neither does the Buckmark, for that matter.

Edit to add: tapatalk on my phone does funny things sometimes. I thought this thread was only a page long and I see I answered a question that has already been answered. Sorry!

Reading and responding to posts on my phone is a PITA, too. :D

Regarding the Neos Carbine, it is light and small for sure. In use as a takedown gun, it really is less than ideal compared to other types. I say this because when the barrel is removed, you have a loose slide, striker, and two springs. While the rifle barrel comes off easy, it is more of a pain to install compared to a pistol barrel. All that length fights against trying to line up what goes over and into the striker housing while trying to get that little thumb nut started. It is not quick on assembly like one would think it would be.

As much as I like my Neos carbine, a lightweight folding stock or sliding stock rifle would be better for a pack rifle in my opinion.
