Brownells recently released its newest version of the company’s popular Retro line of AR-15s, dubbed the BRN-605. The Colt Model 605 provides the inspiration for Brownells’ newest carbine. Predating the M4, CAR-15 and XM177, the Colt Model 605 is an important benchmark in the evolution of the M16/AR-15 and its variants that lead to the M4.
“The original Model 605 was produced in the mid-1960s,” said Brownells’ Paul Levy. “It was never really successful, wasn’t adopted by anyone. It was a stepping stone into later carbine models, and what we have today as the M4.”
Brownells BRN-605 Features
The BRN-605 utilizes a replica of the XM16E1 upper and lower receiver. Collectors will appreciate the partial “magazine fence” on 605’s upper receiver. Also, the metal surfaces are finished in matte gray anodizing. The carbine sports a forward assist, while it lacks a shell deflector.
The shortened barrel measures out at 15.5 inches, while a pinned and welded 3-prong flash hider stretches the contemporary version out to 16 inches, and away from any SBR requirements. Above all, despite the shortened barrel, the 605 features a full-length gas system, which should contribute to considerably pleasant shooting. Meanwhile, an enlarged gas port helps ensure proper function and reliability. As such, Brownells recommends using 55-grain bullets in the BRN-605.
“What that results in is a handy little carbine that is unique in the history of retro guns,” said Brownells’ Paul Levy. “And it’s soft shooting. You have a relatively short barrel, a long gas system, so the recoil impulse is really soft.”
Black “Type D” furniture, of modern reinforced polymer, completes a classic look sure to please AR buffs. The combination of the fixed stock and triangular handguards certainly capture the image of early-pattern ARs.
