Canadian C3 barrel length and metal finish

[Lee Enfield]

Thanks for the quick response. I'm going to go with a 26" 1:10 barrel then. With respect to the barrel contour, is the contour in the attached pic close enough?

Cheers.

The c3a1 barrel I measured was. 955" at the torque shoulder tapering to. 900"

Thanks. That's a pretty insignificant taper over 26".

Thanks. That's a pretty insignificant taper over 26".

Interestingly I've been told that one c3a1 barrel measured recently was swamped, ie) tapered to about the mid section, and then reverse tapered to the muzzle.

I doubt the "swamped barrel" was intentional. It was probably due to machining issues. It is hard to eliminate chatter when contouring a long barrel between centres. You tend to get a lot of chatter at the mid point with the least support. One way to address this is to only chuck-up half the barrel, contour it, then turn it around and do the other half. The apparent "swamped" measurement may in fact be just a taper mismatch.

Here are some pics of recent purchases in my quest to build a C3/M82 clone.

The donor action is from a PH 1100 in .308. I also purchased two stocks that appear to be almost new. Why buy one when you can buy two, right?

I haven't received anything yet, so I'll start a new "build" thread once everything is in hand and ready to go.

I'm also going to turn a 27" button rifled 30 cal. 1:10 blank into a reasonable facsimile of a 26" M82 barrel.

Does anyone know if the PH 1100 and 1200 Santa Barbara receivers retained the standard M98 action screw thread (1/4-22) or did they change to 1/4-28?

On Numrich and they have action screw sling swivels with both thread sizes.

Also, I'm planning on making target rails. Any idea what size the holes/threads were? I've ordered hand stops, so I may have to wait and measure the thread.

Thanks.
