First of all you can't buy a new one since Webley is no longer making air rifles. Check used gun lists, they come up a lot. Its the same rifle as the Beeman Kodiak.
The Patriot is about 47 inches long, maybe 8 pounds, and kicks hard. Webley rifles are usually very accurate and the Patriot is no exception. Its not an easy gun to shoot accurately without practice though. Cocking effort is pretty high, near 50 pounds. Trigger is nice, overall quality is better than most. It was available in .177, but that caliber is really to light for the power level of this rifle. .22 is better, but the .25 Patriot is best. The .25 shoots 21 gr pellets at 820+ and can generate 32 FPE with heavy pellets.
