I found this little gem at a local Fun Show.
1985 Mark II with a 10" bull barrel. IN THE BOX and looks like it has never been shot, or VERY little. Thinking of an integral as opposed to s screw on, which I already have coming in the form of a SS Sparrow for my 22/45. I am looking very closely at John Norrell's integral. I am also interested in having the receiver tapped for a picatanny rail and a red dot or Eotech. I plan on a Volquartzen trigger kit....... I AM NOT looking at John's Guns integral. I have seen their work and it trully does suck. Are there any members out there who have a Norrell integral? Other companies, Pros and Cons? |

As far as I understood it 10" MKII's were rare.
Why chop one up to make an integral, when you can make an integral out of any barrel? As far as cons- integrals bleed velocity. So what if you wind up with a gun that gets 920FPS with CCI Velocitor, and it sounds great with slower subsonic loads, but sounds like any rimfire pistol with a muzzle can with velocitor (the only ammo you can get serious velocity with)? We had a $1400 (suppressor only) integral bolt action build in our shop for a transfer once. The gun had a ported barrel and 15 K baffles. It netted 1020 FPS with CCI mini-mags. It metered 114DB with subsonic loads and sounded great. It metered 118 with the CCI mini-mags that produced velocity good enough for hunting. With this ammo it sounded and metered the same as a 16" barrel bolt rifle with typical 6" muzzle can and 1050FPS with subsonic ammo. |

I own a John Guns Mark II integral as well as his 10/22 integral. Both were made by John Tibbetts when quality was high. I have no regrets. But I would not buy from them now, due to the same issues you have.
As far as quality is concerned, TBA is first class, and I have compared many of TBA’s integrals to the two items I own from Johns Guns when the quality was high. TBA’s work is superior, period. (disclaimer: I own an integral CZ452 made by TBA) Just make sure that the choice you make includes a gun that is ported (makes it much quieter), and can be totally disassembled for cleaning. I have not seen Norrell’s work on a Mark II, but I have seen photo’s of his 10/22. In the photos I have seen, Norrell turned the barrel into Swiss cheese, and used modified flat washers as baffles. I did not like the thought of so many ports in the barrel. I feel it couldn’t possibly have helped accuracy. Also modern K baffles are superior to flat baffles. It would be a mistake to modify that 10 inch Mark II. You would regret it later. |
