JR Carbine Unboxing, Firing & Takedown Videos

Thanks for the great videos Farmer Harv, I have been lurking on the black and green rifles forum for a while, thinking to purchase one (my 2 M305s crying out in pain in the basement right now!).

After seeing this I will jump if the JR Carbines make it here in 40 S&W!

Isn't the barrel triangular?

Looks like there's room for a fake can
 
The center ~9" of the barrel is triangular, with about 5.5" inches at the muzzle being round. The barrel looks to be .750 (ruler only...haven't put the calipers to it yet) so there should be enough thickness for threading.

Here's a high speed mockup of something that covers the round portion of the barrel end. Bonus points if you can tell what it's made of. :)

Ahhh, those Spike's look like the perfect fit. My foam is almost exactly 1.5" in diameter, so the SD-1 would be ideal.

Too bad there isn't a slip-on version though. I hate to have to send the barrel off for threading just to attach a fake can.

But I probably will. :)

Any idea what barrel threading is worth?

You are a farmer in Saskatchewan & you don't have a lathe ? ;)
Seriously though I'm sure you must have a machine shop in your area .
If you don't want to thread the barrel you could just get a piece of aluminum round stock the length you want & bore it to slide over the barrel & drill & thread several holes in the tube & use set screws to hold it on :D

LOL! Well, I have one...but as you can see I don't use it much (or very well when I do). :redface: I can only imagine the carnage that would ensue if I tried to cut threads into a nice rifle barrel. :eek: :runaway:

Yeah, that's what I've been thinking. Doesn't affect the rifle permanently, and even with my crap skills(?) I should be able to bore and slightly round the ends of a piece of aluminum. Some plastics (delrin?) might work for a fake can also, although I don't know if it would be much easier to work with than aluminum (and might be more difficult).
 
The only difference between you Southbend 10L and this 9A is the dirt and old paint job. Believe me, that lathe is more than capable of doing everything you need to thread a barrel, IF you know how to use the lathe ;) In fact, the 10L is a more capable machine as it's a little heavier.

Oooooo...nice! Now I'm going to be tempted to get mine cleaned up and spinning again. :) Been years since I did any thread cutting though, and I wasn't very good then. My biggest problem has always been sharpening the cutting tool properly. Well, that and figuring out how to set it up. :redface:

People like me are the reason there are so many successful machinists out there. :)
