Making REM take-off bbls in FAL bbls?

[gunsmoke]

I recall seeing from time to time different people advertise the service here abouts and was wondering if anyone could tell me who was particulary adept at the task I have a number of new pre-fit REM 700 bbls all cahmbered for .308 based ctgs, its time for some fun and experimentation.

Thanks for the info!

I think adam762 has done it as well

Any chance you have an extra 358w and want to trade for one or two 243s?

This has gotten my curiosity going.....

So here are some questions;

-Do the barrel threads match those of an FAL?

-Would you torque the barrel to the receiver? If so, how many ft-lbs?

-If not on the above, would you hand time the barrel, then cut flats?

-I'm assuming the barrel would be chucked into a lathe, then turned down to fit the gas block. Drilled as well for gas port of course.

-The chamber end of the barrel would also have to be cut to allow proper lock-up with the bolt group, and also cut for the extractor. Right?

-Handguards? Other stuff going into making it fit?

I would guess NO. I don't recall Remmy ever offering anything in 358W. Too bad, as it is an excellent cartridge in the field. And my expierience loading it for a guy that had several was that it is inheirently accurate.

I always thought the Rem. pump carbine in 358W would be the titz in the woods.

Thanks, I have no idea what Remington ever built or didn't. I lucked into a few Rem-700 take-off barrels a couple years ago, would still like to find a core for a 358fal, and a couple of 223's. I don't follow the auction sites nor do I know a gunsmith who would acquire them, but I know some of you guys do. Maybe Win-70 take-off can work and be found.

You seem to have forgotten your friend just across the pond from you.

So here are some questions; and some answers

-Do the barrel threads match those of an FAL?

FAL=1X16 Rem is like 1.0625X16 ( got to turn that down and rechase the thread)

-Would you torque the barrel to the receiver? If so, how many ft-lbs?
That would be all teh same

-If not on the above, would you hand time the barrel, then cut flats?
Hand time it with a locking shoulder gaguge in there and chamber gaugge in the chamber while barrell is in the lathe so you can cut and try till it times right.

-I'm assuming the barrel would be chucked into a lathe, then turned down to fit the gas block. Drilled as well for gas port of course.

Yes

-The chamber end of the barrel would also have to be cut to allow proper lock-up with the bolt group, and also cut for the extractor. Right?

Got to get rid of teh ring 2 steps ago. extractor flats, gas nut relief all done on a mill

-Handguards? Other stuff going into making it fit?
Good luck profiling it between centers

Yes

Have you ever done one? I'm thinking no, as anyone who has would know that the gas block ID is a fair shake smaller than the standard Rem Sporter barrel OD when in normal position.

SOP for me is to turn a straight section on the barrel then install a sleeve on it for the gas block.

The other option would be to do a short gas system.

Some sporter barrels have enough diameter that a sleeve is not needed.

Can you explain this? Is it hard to profile between centers? What is the alternative, a steady rest?

Problems with chatter can be difficult to overcome when profiling a barrel between centers. This can often be mitigated by the proper tool geometry, spindle speed and feed rate. Creative set ups using a steady rest or short chucking the barrel will help overcome these issues as well.

richbug, I have never done this, hence why I was asking questions.

mountainman, thank you for answering my questions.

Thanks for the link tdb59.

I'm just a novice trying to further his education.

The barrel in Post 27 of that thread clearly says "Winchester Proof Steel" on it. Not a remington barrel, I clearly stated "Rem standard sporter". The OP asked about REM barrels, I was talking about REM barrels.

I'm going to have to file away the names of Files members who have converted take-off barrels for FAL installs. I've got a take-off .308 barrel from an FN PBR that I've though would make a great shooter for a short gas project. Also thought it would be nice to use an FN barrel for the FAL...
