| What is a "Bentz" target style chamber? Basically it is a tighter fitting chamber, designed to align your ammo straighter and more consistently than the generic SAAMI 22LR chambers that mass production guns come with. The Bentz is especially suited to semi-auto firearms like the Ruger 10/22 because it retains enough clearance for reliable feed and ejection. A Bentz chamber will fit most standard and hi velocity 22 LR ammo BUT NOT STINGERS. |
| What You Need to Know... You can upgrade your Ruger 10/22 quickly and easily if you remember a few simple points. First, these are .920 diameter bull barrels. They have no taper and are most likely too wide to fit in your original factory Ruger 10/22 stock. The easiest (and most fun) solution to this is to replace the stock with something exotic and adult sized. We have several options on our Ruger 10/22 Stocks page. Second, you can't realize the full accuracy potential of these gun barrels unless you use a parallax adjustable riflescope. We have an explanation and can recommend several several good scopes and scope mounts on our Ruger 10/22 Scopes and Mounts webpage. |  Finally, we have some straight forward barrel installation instructions that should give you an idea of what's involved and what to consider. Good luck and Good Shooting! |
