C no.7 / #7MkI

You did. In another thread, you stated you had made a Jaco pistol, and registered it in the "normal" manner.
There are no FRT numbers for any Jaco Design guns, long or short.

you mean my dog training gun lol it only uses a .209 primer and have about a 1/8" bore :redface: (the bore is just to let the gas out
 
If 5/16" liners are being used, a .303 barrel cleans out really nicely. Very, very little steel to remove. If a larger liner is used, a proper drill with a pilot would be needed.
Leaving the bayonet lugs on simulates the British No. 9, which was a converted .303.
With a chamber filler shaped like a .303 cartridge case, the job could likely be done without removing the barrel.
 
if you look close, you can see where the joints are.

Very good and interesting pics Gaff.

What are we looking at?

Are those both barrels that were made up by someone to install on a Cno7 receiver? Basically .22 barrels from another rifle that were machined to fit into a .303 knox form stub?
 
thats right . with the front sight stubs also on win mod 67 barrels.

Looks very slick. Are you doing this work yourself? I see the breech end of the No4 barrel, but can't quite get the muzzle end. Is it a cut off No 4 muzzle end, complete with bayo lugs, that is sleeved over the turned down muzzle end of the Win 67 barrel?
 
Why would you have to have a liner as long as the 303 barrel.As long as the back end is correct the gun can shoot out the larger hole on the muzzle end.
 
gaff you have any .303 barrel cut offs i got some ideas on relining a .410 with one and making it a .32 S&W rifle (can someone say silent without a silencer :) )
 
Hi Guys

I just have a quick question for you, in your parts section you list parts for the #7MkI .22lr, are these parts interchangeable with the C No. 7?

The reason I asking is that I have come into possession of a 1946 LongBranch C No.7 receiver that I would eventually like to complete into a rifle and am wondering if I can use the parts listed on your site to get that goal started.

No. 5 lookalikes in .22LR have been made, as well.
Years ago I had an unfinished C No. 7 barrel with a bad bore near the muzzle, sold it as is. I know it was used to make a No. 5 pattern rifle in .22RF. Big advantage to making a No. 5ish rifle is that the shorter barrel makes finding a suitable .22 barrel that much easier.

I built that rifle up. Worked very well. I used Cno7 magazine, bolthead, firing pin and extractor. For the rear sight i got a spare from a No8 trainer.

VERY fun to shoot. And thanks again for the barrel.

I wonder if that was the rifle I owned a few years ago? It was Canadian marked and green parkerized. Very nice rifle.
