The AR-10 is an air-cooled, lightweight, gas operated, magazine-fed, select-fire rifle that fires 7.62 × 51 mm NATO (.308 Win cal.) ammunition.
The AR-10 was designed by Eugene Stoner and features an aluminum alloy receiver, in-line stock and reinforced fiberglass furniture. Additionally, the AR-10 operates on the direct impingement gas principle. The rifle was constructed in relatively small numbers as it has been frequently noted that only 10,000 rifles assembled.
At the time of its creation, there were extreme differences between the AR-10 and other rifles and the AR-10's appearance was novel and unique. The AR-10 was first introduced in 1956 and weight nearly two pounds (1 kg) lighter than most infantry rifles. The AR-10 was also markedly easier to handle and control in automatic mode and much more accurate in semi automatic mode. Lastly, the AR-10 is commonly noted as handling far superior to any and all of ther weapons fo the period.

Does anyone make a 22lr conversion kit for this?

It will shoot anything, and with $14/box Monarch ammo I can get sub-MOA grouping using a mid-level Leupold 3-9x. At 200 yards, it will reach out & touch a circle the diameter of a tennis ball every time. With Prvi Partizan BTHPs it's accuracy is even better. Tack-driving accuracy at 100 yds, even when firing rapidly from a sandbag.
I have a Rem. 700 in .308 with a $1k scope that the AR-10 puts to shame.
