BRN-4 – Small Arms Review https://smallarmsreview.com Explore the World of Small Arms Tue, 29 Nov 2022 04:30:04 +0000 en-US hourly 1 https://wordpress.org/?v=6.9 https://smallarmsreview.com/wp-content/uploads/2020/05/cropped-online-sar-logo-red-32x32.png BRN-4 – Small Arms Review https://smallarmsreview.com 32 32 Brownells Unveils BRN-4 Build Kits Compatible with HK416 Parts https://smallarmsreview.com/brownells-unveils-brn-4-build-kits-compatible-with-hk416-parts/ Wed, 07 Dec 2022 14:00:00 +0000 https://smallarmsreview.com/?p=35736 Brownells customers can now buy BRN-4 build kits and parts compatible with popular HK416 style rifles and pistols – at a significant savings compared to, rare, hard-to-find factory original kits. The build kits combine brand new Brownells BRN-4 barrels, bolt carrier groups, gas pistons, gas blocks, barrel nuts and other parts with factory original HK416 handguards and stripped uppers. 

Factory-new BRN-4 barrels are available in 10.4”, 14.5” or 16” lengths in either heavy or medium profiles. BRN-4 build kits include the special barrel nut wrench required for installation. 

The stripped uppers in the kits are surplus German-made originals, and part of a one-time lot of parts Brownells was able to source a few years ago. German stripped uppers may show signs of use, are limited in number and will not be replaced once they sell out. Uppers completed using Brownells BRN-4 kits and parts are fully compatible with both HK416-style and standard AR-15 lowers.

In addition to complete kits, the BRN-4 parts can be purchased individually — ideal for customers who need only a part or two to complete or repair an HK416-style firearm.
