May 01, 2013 · Browning Buckmark Custom Carbon Carbine Rifle .22LR speed test. ... This is a demonstration of the Browning Buckmark .22LR semi-auto rifle. It has been customised reducing the overall barrel ... The Browning Buck Mark Sporter .22 LR Semiautomatic Rifle features a matte blued barrel and an aluminum frame with a pistol-inspired design. Overview of the Browning Buckmark. The Browning Buckmark is designed using a blowback action. The frame of the pistol is built out of 7075 aluminum alloy steel, and the magazine holds ten rounds of .22 LR ammunition with one more round in the chamber for a grand total of eleven rounds. I say the 5.5" bull barrel gun would be the best option; based on the fact I own one myself. Mine is a blued version* , just like the one you pictuered; except it is a pre-finger grooved model, and has laminate Rosewood grips. Made in limited quanities, and available through Browning's Medallion Dealers only program.
