I am going to buy a bull barrel for my 10/22, but I am stuck in between an aluminum barrel and a regular steel barrel. My friend said the heavy the more accurate it is, but he said the aluminum barrel sounds like a good one too. It's a tactical solutions. Here's the description, An ultra lightweight replacement barrel for the Ruger 10/22. Each barrel is precision machined from solid aircraft aluminum and incorporates a premium button rifled chrome moly steel liner. Technical Information Notes: Barrel is machined from 6061 T6 aluminum bar on CNC machinery Barrel has a premium chrome-moly liner Oversized shank allows for custom-fitting to the receiver, this can be accomplished with light sanding of the barrel shank Barrel weighs 15.2 oz Thanks.
