However, they do considerably less damage and are less conspicuous than 5.56mm full-power options at their disposal such as the Tavor or M16 variants. These rimfire rifles are essentially used to bridge the gap between less-lethal crowd control measures such as baton rounds and rubber bullets and very damaging service rifle fire. They offer greater accuracy and improved range over most less-lethal options and can be highly effective at incapacitating key members of violent riots with less risk of fatalities and collateral damage over 5.56/7.62mm weapons, which they are frequently used alongside with. Here is an article discussing the SR-22 rifle in this role: http://www.thefirearmblog.com/blog/2015/10/21/israel-adopts-ruger-sr-22-in-less-lethal-sniper-role/ An Israeli soldier carrying an SR-22: As you can see, the Israeli-adopted version is non-suppressed, features a magnified optic, and is fitted with a bipod. I am interested in building a clone of this weapon and am wondering if anyone out there knows the specs for this gun? The muzzle appears to have an aftermarket muzzle device and I'm wondering what it is (I know it's hard to tell from the picture). I am also wondering if anyone can identify the optic? I think it would be very cool to essentially create a true "military spec" rimfire rifle that is actually used in real conflicts. If anyone has any additional details or info on the use of the Ruger SR-22 rifle in Israel, that would be greatly appreciated. Feedback or opinions on the base SR-22 are also very welcome, particularly on accuracy over a standard 10/22. Thanks so much!
