The AR-556® rifle with free-float handguard is now available chambered in .300 Blackout.
This addition to the Ruger® AR-556 rifle line features a 16.10" cold hammer-forged barrel with a 1:7" twist and pistol-length gas system to reliably function with both the lightest supersonic hunting rounds and heavy, subsonic rounds.
The rifle also boasts an 11" aluminum free-float handguard with Magpul® M-LOK® accessory attachment slots and a standard pistol grip for easy user customization.
The dust cover and metal magazine are marked with the caliber for easy identification of both the rifle and ammunition. The pistol-length gas system is tuned to run with a wide variety of ammunition, with or without a silencer. The 5/8"-24 muzzle threads are capped with a thread protector.
I purchased this rifle from Sportsman’s Outdoors in February 2020 ,on sale for $539.00. This is a no frills weapon Does not come with iron sights however for the money it is good quality. I threw a Holosun green dot on it and some angled after market backup sights. I did have some pretty serious cycling issues with a cheap brand of supersonic loads but I believe it was due to poor quality of the ammo more than any defect with the rifle as it has over 2000 rds of some decent subsonic rds through it without any issues . Overall a great entry level Ar platform at a great price
Was a great transaction, A: I got a hell of a deal, thank you B: Ran through the ammo Flawlessly C: It also looks cool I'm having some sight issues but that's not the guns fault i'm thinking operator error. Gun is an absolute riot. i added a vert grip, angle irons, laser, and a red dot lol supressor and performance triggers would really make this ar top notch.
The rifle has a very stiff trigger. I am guessing 7-9lbs trigger pull. The coating on the shell deflector has worn to show metal after 100 rounds. It works as it should but expect a trigger upgrade in the future. I won't recommend against it however I expected better quality from a Ruger. 4 stars.
