BRN-4: Brownells’ HK416 Clone Lower And Parts Coming This Veteran’s Day

    If you recall, The Firearm Blog broke the news back in March that Brownells was importing HK416 components. They first offered their HK417 parts for sale back in early September. Well now they will be selling their HK416 parts as well as offering their newly manufactured parts up for pre-order on Veteran’s Day, Monday November 12. Their 416 profile lowers, the BRN-4, will also be up for pre-order.

    Brownells acquired a large quantity of HK 416 forged blanks and they will be offering them as fully machined 416 profile lowers. One of the biggest concerns was how Brownells would be marking their lowers: according to my contact, the manufacturer’s markings will be on the front of the mag well. On an MR556/416 this is where they have “WARNING: Read Operators Manual Before Use”.

    See the sample below (Note: it will say Brownells instead of PWS). And just like the HK MR556/416 the Brownells lower will have the serial number engraved and color filled above the trigger pin on the same side as the bolt catch. Brownells is calling their lower the BRN-4. You may notice the lower has a M16 sear pocket milled into the receiver. Brownells says they will have a standard AR-15 trigger area cut.

    This lower is perfect for clone builders. This allows for a clean slate to get the BRN-4 laser engraved with clone markings – they can mark it with all the HK 416 markings.

    078-000-487 BRN-4 STRIPPED LOWER RECEIVER

    BRN-4 Stripped Lower Receiver, machined from original HK416® forging out of Germany.

    Brownells started with a raw HK416® forging, and had them machined by Primary Weapons Systems to be as authentic as possible. These lowers feature the classic contours of the HK416®, found on now other lower receiver. Selector markings are inspired by HK416® markings, with color filled pictogram markings. The FFL information is machined on the front of the magazine well, where the normal HK416® warning information is placed. Following machining, these receivers get a matte black Type III anodizing.

    The BRN-4 is compatible with all standard AR-15 components, and is right at home on an HK416® build or a custom AR-15.

    Along with the lower, Brownells will be offering parts kits which you can see below. With their newly manufactured parts you can complete the parts kit and build a 416 rifle.

    Sourced directly out of Germany these parts kits include all item necessary to build up a 5.56mm 416, less the lower receiver, bolt, and barrel. These parts are not included due to German export law.

    One of the 416’s most notable design differences is the short stroke piston system that has led to a reputation for amazing reliability.

    These kits will include the upper receiver, handguard, gas block, bolt carrier, and piston system, charging handle, all lower receiver small parts, buffer and buffer tube assembly, and stock.

    All you will need is the barrel, bolt, and receiver. Last March I learned that Germany does not allow its citizens to possess bolts or barrels. But you can have everything else. Brownells acquired these parts kits from ZIB Militaria and they did not have bolts or barrels to sell so Brownells had to have them made.
