What is brn180?

Brownells 180 BRN-180 rifle  Complete Upper Receiver is inspired by the Armalite AR-180 of the 1960s. Developed as a successor to the original AR-15, the AR-180 was a civilianized version of the AR-18, itself an upgrade on the M16 platform.

The BRN-180 incorporates many of the AR-18/AR-180 improvements – including its robust and reliable gas piston operating system. (Yes, the originators of the AR-15 / M16 eventually embraced a piston.

The 16″ barrel is machined from extra-strong 4150 carbon steel, with a hard Nitride finish that really resists surface wear. The brownells brn-180 rifle is chambered in .223 Wylde – for extra flexibility in ammo choice – with 1-8″ rifling, so it handles both .223 Remington and military-type 5.56mm NATO(North Atlantic Treaty Organization) ammo with equal aplomb.

Up front there’s a replica of the AR-180’s unusual three-prong flash hider: the hemispherical bottom prong helps prevent the muzzle blast from kicking up a dust signature when shooting prone.

Brownells BRN-180 Semi-automatic Rifle one of the country’s top shooting-components providers, has been a longtime supporter of this country’s enthusiasm for AR-pattern rifles. When I built a direct gas-impingement operated AR-15 at home for the first time a few years ago, this company proved to be an invaluable source of tools and information for the first-time builder and more experienced at-home hobbyists.

Although I have yet to find any reason to complain about the performance or reliability of the well-made direct-impingement platforms I’ve worked with, plenty of folks are devoted to ARs that use short-stroke gas-piston systems to cycle the action.

They run much more cleanly, since exhaust from the cartridge is not being blown back into the action. They also don’t heat up as quickly, for the same reason. However, piston guns do tend to cost more and generally don’t print quite as tight of groups as impingement-operated guns.

The debate over which is the better action type for an AR will continue. Rather than just watch from the sidelines, I opted to get into the game by building a piston driven AR in order to see the differences for myself. Once again, thanks to new-products released last year and this year, Brownells has made building a piston AR just as easy as an impingement model. BUY a our COMGPLETE BUILD HERE!

Brownells BRN180 For sale could have gone in a variety of directions to develop in-house piston driven options for their customers. In 2019, it opted to go the retro route with the launch of the 5.56 NATO/.223 Rem. BRN-180 series of factory complete AR-15 uppers inspired by Eugene Stoner’s AR-18/180.

As a scaled-down version of the AR-16, the AR-180 sported a piston system that was ahead of its time. However, other features and factors in play at the time kept these rifles from being adopted by the military or picking up much steam in the civilian market.

Rather than try to replicate the AR-180’s stamped-and-welded steel receiver, the BRN-180 uppers are assembled around milled billet 7075-T6 aluminum upper receivers, which are compatible with mil-spec AR-15 lowers and typical AR-15 STANAG magazines. This gives customers the option of snapping this upper into a lower they already have or using it as the starting point for a simplified at-home build.

The flattop upper receiver has more of a square profile than the typical AR-15 along with an integral Picatinny optics rail. On the left side of the receiver is a cut out to accommodate the bolt catch and a small round rubber bumper to protect the finish if a folding stock is installed.

On the right side of the upper receiver is a modified polymer dust cover fitted to the ejection port, but a the familiar AR-15 forward assist is absent. The top mounted non-reciprocating charging handle has been replaced with an AR-180 type reciprocating bolt handle which protrudes from the ejection port.

Within the upper receiver, a rotating multi-lug bolt is fitted into a block-shaped carrier supported by dual recoil assemblies. The recoil rods are mounted to a removable aluminum cap that’s held in place by the lower receiver. This means the recoil assembly is fully contained within the upper assembly with no need for a spring or buffer to be installed in the shoulder stock.

The BRN-180 upper ships with a 4150 steel, button-rifled barrel with a black-nitride finish and a .223 Wylde chamber. The upper is currently available in three barrel lengths including 10.5″ pistol, 16″ carbine and 18.5″ rifle options.

I opted to work with the 18.5″ rifle barrel with a 1:8″ twist rate and a factory-installed replica of the AR-180’s three-prong flash hider. The 14″ long aluminum handguard free-floats the barrel, has a full-length optics rail on top and M-LOK accessory slots cut throughout.

The handguard is secured to the barrel block by a U-latch. Removing this latch allows the handguard to slide off in order to provide access to the gas-piston system. The piston system’s design is lifted straight from the AR-180 with some modifications to the spring, materials and finish to bring it up to modern production standards. The upper arrives with a standard piston cup installed, and a second cup for sound suppressors is provided.

The rifle came together beautifully with no technical problems or component fit issues. The BRN-180M lower has a screw in place of a roll pin for the bolt catch, and the rear takedown pin detent has been moved from the buffer tube port location to a point just above the pistol grip. That detent’s spring needed to be shortened a bit before installation.

There was no need to swap out any of the originally planned components for this particular build. Once completed, the BRN-180 sailed through the bench checks, passing each one with aplomb.

For the range test, the BRN-180 build was outfitted with a Bushnell SMRS Elite Tactical 1-6.5x24mm scope using a Weaver Tactical SPR Optics Tactical Rail Mount. The rifle operated reliably with a variety of ammunition and AR-15 pattern magazines, including the Mission First Tactical (MFT) Extreme Duty 30-Round magazineshttps://westcostsecurity.com/shop/semi-automatic-brownells-brn-180-rifles/https://westcostsecurity.com/shop/semi-automatic-brownells-brn-180-rifles/https://westcostsecurity.com/shop/semi-automatic-brownells-brn-180-rifles/Formal bench rested accuracy testing was conducted at 100-yards by firing five 5-shot groups into paper targets. Gorilla Ammunition’s 77-gr. Sierra Match King open-tip match load printed a best single group of 1.84″ with a five group average of 1.88″.

Winchester’s Select Grade USA Ready 62-gr. open tip tapped out a best group of 1.51″ with an average of 1.65″. Norma USA’s Tactical 55-gr. full-metal jacket was the tightest shooting load of the test with a best group of 1.32″ and an average of 1.45″.
