my first can was one of Keiths aluminum 22 cans. worked so good later i had him build an integral on my old ruger mkI. we just started paperwork on a 223 can this past week. he does great work at reasonable prices.
With the election things have been tough to keep in inventory but we should have some of both 22 cans available.
The Warlock is a little better than the Outback but both are excellent and i personally own both. If someone were switching between a Warlock and Outback next to you it would be difficult to tell when the cans was swapped but paying close attention you can determine the difference.
