Product Description

What's in the Box

  • Beretta ARX100 5.56mm Semi-Auto Rifle
  • (1) 30-Round Magazine
  • Rifle Sling
  • Soft Rifle Case
  • Owner's Manual

The ARX100 features a constant contact/short-stroke gas piston system that makes it feed and fire under the most unforgiving conditions. The lightweight technopolymer receiver allows for reliable operation with virtually no lubricants. To make maintenance easy and trouble-free, this rifle has no pins and can be completely disassembled in a matter of seconds with no tools at all.

This rifle was designed to be completely ambidextrous, and all the critical controls on it may be operated right- or left-handed. These include the 2-position safety, the magazine release, the bolt release and charging handle and the case-ejection selector, which determines whether spent brass is ejected to the right or left. The flip-up backup sights that come standard on the ARX100 are also versatile, offering an easily-adjustable diopter system ranged from 100 to 800 yards. The barrel is also easily replaceable in seconds, making is possible to use different lengths and calibers without any tools required. Lastly, the folding stock is adjustable for length of pull at the touch of a button, using a simple and rugged telescopic construction.

(5 out of 5) Excellent addition to your collection
by Stephen from Davenport, Iowa on January 1, 2018

I want another 223/5.56 gun but wanted something different then another AR. Don’t get me wrong I love my AR’s and in the future I will be purchasing more but just wanted something a little different. My son had pointed out the ARX 100 awhile ago and when they put it on sale he jumped on it. I liked it so much I purchased one. For $900 I couldn’t resist. I was not disappointed. I love the looks and the way it feels. It is lighter then my AR’s but feels very well built. It has shot anything I put through it so far. The gun is fun to shoot. I picked up the ARX 160 22lr to add to my 22 collection. On magazines, it will not take Gen 3 Pmag but will take Gen 2, Lancers, the Steel magazines I have and Hex magazines. I wish it took the Gen 3 but it isn’t a deal breaker for me. So if you want something in 223/5.56 but want something a little different then another AR this is it. I highly recommend this gun. For now I put a Burris AR-332 on it and purchased the bottom rail replacement from Beretta and put a Angled Grip on it. It had the WOW affect at the range and I got a lot of compliments on it. You can’t go wrong with this gun.

(5 out of 5) ARX-100
by Rob from Colorado Springs, CO on February 22, 2018

The ARX was listed at such an incredible price I could not resist. After taking the gun out for a shoot for the day, I was sold. There are mixed review about this Italian made 5.56 but I gotta tell you for the price it was very fun to shoot and was more accurate then I am.

(1 out of 5) Complete Junk
by Sean from Tempe, Arizona on March 19, 2018

Note: This review is about the Beretta ARX-100 and NOT Sportsman's Outdoor Superstore. Sportsman's customer service and shipping was outstanding, the rifle and Beretta are another story. This rifle looks and feels cheap, flimsy and very poorly made. Charging the rifle feels like clunky steel rubbing on cheap plastic because that is exactly what is happening. My rifles bolt carrier had most of the finish chipping off like old paint. It also had awful machine marks that I have never seen on a modern firearm. The barrel in my rifle also didn't fit correctly and wobbled around. I sent pictures of this to Beretta and they wanted me to send the complete rifle in to them and pay for it. This was just one of the issues I had with their poor customer service. Even though this rifle is marked down over 50%, clearly an indication of how poorly it is selling, I would avoid it and Beretta completely.

(5 out of 5) Great!!!
by Charles from Fayetteville, NC on April 9, 2023

This rifle is a fantastic alternative to a standard AR15. 100% ambidextrous, if you want to change which direction the rounds eject from, you can. Too bad Beretta discontinued this rifle.
