“M27” inspired Quad Rail Handguard for the BRN-4™ and HK® 416 platforms
Available in 11 and 9 inch lengths, the BRN-4 M27 handguards are suitable for a variety of barrel lengths and applications. The 11 inch model is right at home with the BRN-4 M27 16 inch barrel, as it covers up the gas block and provides plenty of picatinny rail real estate on a rifle platform. The 9 inch model is right at home on carbine builds, especially a handy 10.4” model.
Unique to Brownells BRN-4, these quad rail handguards are available in Flat Dark Earth. The handguard by itself on a matte black upper receiver has a distinct and unique look, and breaks up the overall profile of the firearm. Also unique on the Brownells BRN-4 quad rail handguard compared to similar handguards, is the machined in locking bolt hardware. This ensures the clamping forces are evenly spread to the body of the handguard, optimizing clamping force. You don’t have to worry about zero shifting with this setup.
Indexing tab at the top interfaces with the BRN-4 upper receiver and prevents rotation.Handguard attaches directly to any Brownells BRN-4 upper receiver group, and is also compatible with HK®, 416, MR556 and MR223 platforms.

We stock both premium factory-new components and high-quality once-fired brass. Please check the specific product listing title and description carefully; once-fired brass is fully inspected, but we always recommend resizing and inspecting prior to priming and powder charging.
Our standard reloading dies and case length trimmer accessories utilize industry-standard threads (typically 7/8"-14) compatible with major single-stage, turret, and progressive presses like RCBS, Hornady, Lee Precision, and Dillon. Caliber-specific trim gauges must match your exact brass caliber.
Yes. Non-hazardous reloading equipment (dies, case length trimmers, gauges, and unprimed brass) ships via standard ground carriers with no extra fees. Any orders containing smokeless powders or primers will incur standard federal HazMat handling fees and cannot be shipped via air transportation.
Precision reloading gear is valuable, so all orders are shipped with tracking enabled. As soon as your package is dispatched from our inventory warehouse, a tracking number will be emailed to you. You can monitor your shipment directly on our Track Order page using your unique Order ID.
We accept returns on unused, unaltered tools, case preparation equipment, and unopened component boxes within 30 days of item delivery. Due to safety and strict quality control on the reloading bench, we absolutely cannot accept returns on opened packs of primers, smokeless powder, or processed brass casings.
