From Brownells . . .

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.

To see the full lineup of BRN-4 kits and parts, visit the BRN-4 page at Brownells.

  1. Well, ONLY if it isn’t shipped using UPS. Otherwise it’s likely to be confiscated and destroyed before it ever gets to you.

    • I’m sure Brownell’s has signed up for the UPS gun shipping program. It’s BS but what real option is there right now? FedEx is a nightmare to deal with for any packages, not just guns.

  2. HK, stupid company making standard Colts with a piston
    system and charging $3,000 a rifle. I’ll stick to POF, PWS, and Adams Arms. They cost around $2,200 and have significant other upgrades that come with them anyway.
    Am happy to see HK get undercut by Brownells.

    • Pish, posh. If you have to ask about the price, then you can’t afford one.

      (Relax, I can’t afford one either).

      • It’s not about affordability it’s about stupidity. Just because someone tells you they’ll sell you a rifle for $3k doesn’t mean it’s actually worth that. Always happy to see a too big for their britches company get knocked down a few pegs. HK is the company who for many years refused to sell to civilians because civilians were “not good enough to have our guns.”
