    Posted: April 13 2023 at 1:00am
Ever since the first time I took down the 2A1 "jungle" carbine, I realized a discrepancy in the finish along the barrel. There is a set of marks where Navy Arms' professionally "Bubbarized" rifle seats the inner band into the (what I imagine to be a cut down No.1 Mk3?) fore stock... But there is also another set of finish wear of mounting marks further up the barrel.

In doing some reading of enfield accuracy, bedding and barrel mounting are pretty important for some kind of harmonic feedback to stabilize the whole arrangement? (Proly thinkin too much abt it all, but my science-brain aint been tweaked on in a long time, so enfield science has taken up residence Ermm)

here are some pics of what I'm referring to:
2A1 JC inner band in approximate mounting position (I note ~1mm gap in the ring to the barrel)


Adn here's that band where the old marks show (there's even still more wear of barrel coating to suggest it may have even been snugged further back?? I note about a third of the gap between band and barrel compared to the first pic.)

IS this even relevant, or am I bein silly? or is this an artifact of the Navy Arms importerizing process?

Thanks in advance for thoughts y'all ^_^

Those faux jungle carbines was just an invention to cash in on the idea of owning a No5 carbine.
strickly marketing in my opinion. Though cool in there own right, a bloody waist of an original rifle.
I wouldn`t worry too much about whats what or why on your rifle, it is what it is. Clean it, shoot it, luv it, and shoot it some more.
shoot em if you got em

At one point in time it was relevant and that was when the rifle was in its original condition. Since it has been modified and the barrel shortened to mimick a No5Mk1, the part you have a concern about, while still being a functioning item to snug the barrel down to the stock is in retrospect, a redundant part of the whole operating system. For example. The rifle pictured on top has had 2.5" of barrel removed and the sporterized forend does not support the muzzle like the original configuration as represented by the rifle on the bottom. In this case, the sporterized forend, while still being a functional part of the whole operating system, becomes the redundant part. You have a rifle that can still be used and that is all that matters.  Enjoy it for what it is...

A couple of things to consider.
In the original fill full length military stock that ring & its compensating screw would be further out, in a piece of the stock that no longer exists. It was designed to push the barrel up so the muzzle was in contact with the little "tabs" at 11 O'clock & 2 O'clock in the opening in the nosecap, which is also no longer fitted. Any possible "compensation" is unlikely in its current position!
The entire compensation thing was pointless after they switched to the MkVII bullet from the Mk VI, which it was designed around anyway.
If it's not holding the muzzle against the "seats" at 11 o'clock & 1 o'clock in the nosecap its dong diddly anyway!

Many many years ago, my dad bought a 2A1 "Jungle Carbine" from a very unscrupulous vendor at a gunshow who claimed it was an experimental version that was contracted out to Gibbs to produce except this one was done up by Golden State Arms Santa Fe Division.  My dad and I both knew the man to be an absolute liar but he just followed that old saying, "Buy the rifle, not the story." He paid $100.00 for the thing and he has yet to shoot it. According to my uncle, its been sitting in his closet for the last 25 years...

A lot of the "tanker" & "Jungle Carbine" conversions wee done so a cord-worn bore could be bobbed & so make a "bad" rifle into a saleable product as most of the cord wear is up at, or near the muzzle!

Thanks for the responses, everyone!

On the one hand I was concerned if my rifle will be wonky with that ring in a non-original placement. But on the other, I was interested to know about the history and couple details of the how and why it was there is the first place - thanks for that, Shamu! I did not know about the nosecap index, nor that the resonance thingy was vestigial after a new kind of ammo was developed... I am stoked to know this!!

I did a bunch of digging trying to figure out what it was, and once i figured out it was an NA/Gibbs, and that means its been commercially Bubba'd, I knew it would be nothing more than an historical footnote as far as Enfields go.

My uncle was a C&R, and no doubt purchased this for its probably similar price point, and as a ruggedly functional backup to his CETME (also chambered in also in 7.62 NATO). I'm unfortunately *quite* aware this carbine is in no way a No 5, it being chambered in 308 does make it more accessible to me, as Im not yet set up to reload.

When I inherited it, it too had been sitting in a closet for well over a decade...I am most excited to make it mine, whatever that entails (right now, jus cleaning, lubricating, and general reconditioning... I'll make a different post to share some pics of that as it comes along).

For now, I intend very much to simply make and keep it nice, and very much yes, enjoy it!
