Purchased a lot of factory gauges, question concerning the errosion gauge

on one end of the gauge it says "FAL ARME MONTEE, CB33" and "avert", "rebut", "service"

One end is highly polished and larger then the rest of the gauge ".307", this area extend for approx. 1.360", then after another 1.360" or so there is a line around the gauge's circumference, then after another 1.360 or so another line.

Seems like a no brainer but does anyone have one of these and if so how is it properly used. Everytime I assume something I get in trouble heheheh
Thx,

Av

IIRC

"avert" Avoid (approaching EOL)
"rebut" Reject
"service" Service

Where'd you get those jewels?

What other "acorns" did you get in the batch of gauges?

STG, Lewis, the box contains 2 headspace gauges, a firing pin height gauge, extractor wear gaug and a bore gauge. My box set is Israeli, the errosion gauge is belgium (I think), but its handle unscrews and fits in the bore gauge perfectly, The box appears to be the same wood as my izzies, looks unissued, some surface rusting of the extractor gauge but very very minor

Stg, I dunno really, I was told it was a bore gauge (bottom left in the first pic), it's diameter measures just a hair over .299 using my caliper, Its also threaded, I believe to accept a handle, (my errosion gauge handle fits it perfectly) so I would think its used to measure/check something that has depth (bore?) but im not sure and even if it is, what would be its purpose in life, make sure the end of the barrel isnt mushroomed??
what else would fall in the .299/.300 range?
just dunno....anyone know or have a good guess?

thx,
Av

Here is the Australian Regulations pertaining to gauging of L1A1 barrels;

Barrel Plain Steel Bore

Ensure that:

a. The 0.297 inch plug gauge passes freely through the bore.

b. A 7.595 mm (0.299 inch) plug gauge does not enter the bore more than 152 mm (6 inches) from the chamber end of the barrel.

c. A 7.595 mm (0.299 inch) plug gauge does not enter the bore more than 51 mm (2 inches) from the muzzle end of the barrel.

d. A 7.645 mm (0.301 inch) plug gauge does not enter the bore more than 59.9 mm (2.359 inches) from the chamber end of the barrel.

e. No pitting is present within 63.5 mm (2.5 inches) of the muzzle and the muzzle chamfer is unmarked.


Barrel Chromium Plated Bore (Post 1965 made barrels. From rifle serial number AD6507331 onwards)

Ensure that:

a. The 0.297 inch plug gauge passes freely through the bore.

b. A 7.595 mm (0.299 inch) plug gauge does not enter the bore more than 70.64 mm (2.781 inches) from the chamber end of the barrel.

c. A 7.595 mm (0.299 inch) plug gauge does not enter the bore at the muzzle end of the barrel.

d. No pitting is present within 63.5 mm (2.5 inches) of the muzzle and that no pitting associated with the lifting of the chromium plating is present in any part of the bore.

e. The muzzle chamfer is unmarked and chromium plating run out is even.

That’s all there is too it

ahhhhhh, Thanks G_Fal, Kevin, appreciate the info :)

Would I be correct in assuming these numbers are in regards to new barrels since the errosion gauge has a diameter of approx. .3065?
Hmm however there is a diff in the depths of the numbers versus the e-gauge, more good info please

Question, it appears from kevins post that the .299 gauge should not enter the bore from the muzzle end (post 1965 barrels)

However when I try this test on the barrels I have, the gauge does go, even with new/unissued barrels???

Can anyone shed alittle more light on this for me

Thx

The simple answer to your questioin would be...... What type of barrels are you trying to gauge?

The specs stated are for Australian made L1A1 barrels and will NOT apply to Metric made barrels. As these are made to different specs. There are even different specs between Australian, British and Canadian barrels.

Australian;
See above

British;
Unit, Field and Base Gauge Armourers plug 0.297 in. must pass freely.

Base The leading face of gauge plug 0.301 in. is not to enter the barrel more than 5.2 in. from the breech face.

Canadian;
C1 Bore: 0.298 in.
C1A1 Bore: 0.2995 in.

hope this helps :)

Thanks Kevin, was wondering if the different countries had differing specs, the .299 gauge I have is israeli issue, and the only new/unissued barrels I have are also izzy, so i didnt really expect the gauge to go on them. Do you have the specs concerning izzies?, Appreciate your help, Im learning :)
