Yes you can and the man to see in Mike Sirois at OTT. I think the site is
www.mbmco.netThe ph# is 1-603-750-3232
The ones he makes doesn't require a rimfire adapter block for the breech. I have the first one he made and boy is it accurate, workmanship and finish is top notch. He also made me a 357 Max pistol barrel and it is my most accurate centerfire barrel. Headshots at 100 yds on a squirrel are a regular thing with the 22 lr barrel when I am back home where there are some. At 50 yds I can cover my shots with a dime. The next best thing about it is you do not have to change the breech block to go from center fire to rimfire. Give him a call he is an extremely nice guy to deal with.
