you can buy aftermarket barrels for the Survival Rifle?

that the first I've heard of that. do they aid in the accuracy? do they fit into the stock properly w/o modifications?
I was thinking
AR-7 Customized Accessories, LLC, among others. Yes, the after-market rifle barrels usually usually fit any and all make of the AR-7, and the "more sturdy" ones (read: anything not the Henry AR-7's factory barrel) allow for hyper-velocity ammo to be used. A barrel w/shroud is an oft lusted-after item, for the AR-7 man/woman.
Majestic Arms can set you up with a real lovely barrel/scope mount setup, able to handle any ammo and really fix-up your accuracy, if you so choose. At that point, the argument becomes one of "
is it worthwhile to turn this into a target rifle" - a topic the 10/22 owners (and 10/22 haters) are familiar with, no doubt...
Dino's a good guy, anyhow - I got my "extended AR-7 bolt-handle" from him, and he was friendly and helpful. Ordering a barrel from the US...well, he'll help you arrive at some legal way, I'm sure.
The Explorer II (i.e. AR-7 pistol, aka the Mini "Mauser C-96")'s barrel is indexed differently than that of the rifle, so some "operations" will be required to fit it to an AR-7 rifle. And the pistol-barrels are scarce-enough in their own right, so think before modding one up...
David, thanks for your advice. I'm a little hesitant to admit I carried my AR-7 in my briefcase-satchel for the better part of two years, contained only in two "8 1/2 x 11" bubbled-interior package-envelopes, but I did!

I guess it was the soft "walls" of the briefcase-satchel that perserved the 'fingers' of my Henry AR-7. And yes, it was trigger locked...I kept the receiver locked and out of the stock...snuggled next to 2 of the 100-round boxes of Minimag also in the satchel. Ah, those were the days...
Um, yea...I guess that's all I got for now. E-mail the guys at Henry if you've got any doubts - Anthony was very open about the AR-7's shortcomings, and he put me in touch with a foreman there who (when I was getting a lil frustrated in my search for reliable-feeding ammo) offered to send me any replacement parts myself & my gunsmith deemed necessary, including a brand-new barrel. Maybe I'm too honest for my own good

, but I declined the barrel/parts offer after discovering Minimags gave me 100% reliability. Perhaps some future E & E fellow will appreciate my candour? Hint, hint, hint...
Happy shooting, folks.
P.S. Yes, the Henry was my first .22; that explains why I say I discovered Minimags at that point in time - this was still very early in my shooting career!
