Feb 27, 2006 · I think if Armalite made the improvements that would make it comparable to the XCR, I would give up trying to get an XCR and get the 180B. Ar 180 + TOp rail or quad rail, metal lower, and folding stock, and ability to change the muzzle brake. = a good ALTERNATIVE to the XCR.

If you’ve used an AR-15 or any non-bullpup 223 Modern Sporting Rifle, you can probably figure this rifle out quick. The safety, magazine release, magazines, and trigger are either directly from the AR-15 or very similar. Instead of a non-reciprocating charging handle, it uses a fixed, reciprocating handle attached to the bolt. There is no bolt rele...
With more moving parts, the AR-180B can be a bit less accurate than the AR-15. The heavy stock trigger doesn’t help, but many AR180B owners still report being able to shoot groups of 1-2.5″ at 100 yards. That’s still better than many other modern sporting rifle designs.
The AR180B uses a short-stroke gas system that is extremely similar to that of the WWII SVT-40. The fixed piston stays attached, while the vented gas cup/cylinder travels over it during cycling. Nothing wrong with this system: it’s reliable, keeps powder fowling way up front on the rifle (instead of dumping it into the bolt/action like the AR-15), ...
Shooting the AR180B at the range is very similar to firing an AR-15, with a few minor differences. 1. The stock is not straight line, it’s dropped a bit. This means that your iron sights & optics are lower and closer to the barrel. 2. The bolt is very smooth to operate. 3. It’d be nice to have a bolt release like on an AR-15. I dislike using my lef...
The AR180B is thoughtfully designed and features an easy disassembly. 1. Just below the rear sight is a trough where you can insert a 5.56 cartridge, punch, nail whatever, to push forward on the rear plate. 2. Rotate the rear of the rifle upper upwards just like you would an AR-15. 3. Remove the recoil springs and guide rod assembly. 4. Move the bo...
Polymer lower. The front pivot point holds the upper and lower together and it’s metal pin acting on plastic hinge. If you use an AR-180B in winter when that polymer is brittle or if you’re abusive...Lack of a picatinny rail on the receiver is somewhat offset by the easy-to-add Stormwerkz rail. Or, find a competent gunsmith to permanently add a section of rail to the receiver.Lack of factory support is something of a problem. You probably won’t find many replacement parts at your local gun store.The stock trigger sucks.If you’re in the US, this is a bit of a silly firearm to own. CNC machining is a lot cheaper these days, so the cost for a new AR-15 is much lower and they’re a more ubiquitous platform. If you’re in Canada, it’s a different story because only some firearms are granted “Non Restricted” status. For non restricted, semi automatic 223 rifles, it’s sli...
Feb 18, 2015 · Armalite fixed the problems, but they lost traction and ultimately the race to become America’s standard issue rifle. Armalite of Costa Mesa California was too small to mass produce the AR-18. Howa Industries in Japan was contracted to manufacture the weapons, but just as production was underway, the Japanese government banned the sale of small arms to belligerent countries involved in the ...
There are a pile of 180B clones in Canada. I wrote a post listing and comparing them and the parts available. That's a good summary that I'm sure will help clear up the details for new shooters. I'm glad to see the growing support of the 180 platform by various manufactures.
Mar 31, 2005 · The upper is stamped with the ArmaLite logo on the left side along with the model designation and caliber. Shots Fired. The AR-180B has several features that enhance its accuracy. For example, to stabilize most popular .223 bullet weights, ArmaLite uses a 1:9-inch twist on the AR-180B's 20-inch-long barrel.
Jun 1, 2015 · In 1996 the ArmaLite brand was purchased by Eagle Arms and Eagle Arms President Mark Westrom adopted ArmaLite as the new brand. In 2001, Westrom introduced the AR-180B; an updated version of the AR-180. Several modifications had been made. The first was the lower receiver is made from polymer rather than stamped sheet metal.
