Brownells expands its throwback, retro series with the new BRN-605 carbine. The BRN-605 is chambered in 5.56 NATO and built on a XBRN161E lower paired with carry-handle upper. The BRN-605 features a 15.5-inch A1-profile, skinny barrel with 1-in-12-inch twist. The barrel is topped with a three-prong duckbill flash hider pinned and welded onto the barrel.
The carbine offers a windage-adjustable A1-type rear sight drum nestled inside the carry handle. The build sports black furniture made with reinforced polymer that replicates the look of Colt’s Model 605 — the carbine the BRN-605 pays homage to.
“Before there was the M4 or the CAR-15 or the XM177, there was the Model 605 – Colt’s very first effort at producing a carbine variant of the M16 rifle,” Brownells said in a statement on its site. “And now, with the Brownells BRN-605, for the first time ever, you can own an affordable, nice-shooting reproduction of that first AR carbine.”
