Enfield 7.62mm barrel ID?

[TJ429]

Hello,

I'm looking for some help with the ID of a bbl. It appears to be hammer forged, had some type of foresight sleeve or clamp at one time and has the following specs:

Caliber: 7.62mm (marked on bbl)
Length: 26 13/16" muzzle to shoulder, 27 1/2" muzzle to end of threads.
Weight: 69.9 oz (4lbs 5.9oz)
Dimensions: 3/4" at muzzle, 1 1/4" at shoulder, has a gradual taper from muzzle to approx 25 1/8" and then flares to shoulder for last 1 1/2" (approx).
Markings: "FB613" (poss EB613) near mid-bbl, "V" near chamber, the following markings over chamber: "7.62 M/M", "2.01*", "NP", unidentifiable mark over "89" and "20 TONS".











When I set the bbl in an Enfield Enforcer stock and handguard, the horizontal edges of the stock and handguard do not touch/come together.

Any info would be much appreciated.

Thanks much.

Ted

It's a commercial barrel made for the commercially produced 7.62mm target rifles based on Enfield No4 bodies

Peter,

Thanks much for the info.

Any idea what type of foresight was typically used on these? Two Screw clamp-on type, sleeve that was silver soldered, Enfield No4 type (similar to L42), other...?

Thanks.

You can find clamp-on types, and soldered types, fitted. Often the end of the bbl is turned down so that there is no step visible.

Mk VII,

Thanks much for the info.

The FB613 is the steel mix make and number for record purposes. IN this case, Firth-Brown 6-13.

I have seen a few of these barrels turned to suit on needy L39's and 42's. The extracor slot needs to be re-cut as does the muzzle to take the No4type foresight block band. But in any case, the internal diameter of the block band needs to be opened up by about half the depth of the recesses. This was done to prevent bulges at the muzzle

Peter,

Thanks again. I've got plenty of No 4's to use as a donor and have 7.62mm magazines and extractors. Looks like another project for the gunsmith.
