­  Ruger finally breaks into the AR-15 platform world with their SR-556, a gas-piston rifle chambered in 5.56, with other specifications lining up with the mil-spec regulations that we all know and rely on. The SR-556 a two-stage gas driven system with 4 different gas settings, chrome lined and plated components, Troy Industries quad rail and Troy Industries flip up irons. This is the definition of a ready-to-go set up featuring the most sought after features in the AR15 world.

    The SR-556 offers Ruger's legendary rugged reliability and employs a patent-pending, chrome-plated, two-stage piston-driven operating system that provides the user with a cleaner, cooler-running, reliable firearm that is truly state-of-the-art. The chrome-lined gas block and chrome-plated piston and regulator work together to provide a smooth power delivery stroke to the bolt carrier, and the by-products of the gas system are vented out the bottom of the gas block, away from the bolt carrier, keeping the action clean and free from contaminants. This results in significantly improved performance over gas-driven rifles. The Ruger SR-556 features folding iron sights, a quad rail handguard providing four MIL-STD 1913 Picatinny rails, a manganese phosphate/hardcoat anodized finish, and three PMAG magazines.

    Received my SR556 yesterday. I have to say for my first rifle I didn't go wrong. I have always liked Ruger small arms but this rifle has me completely sold in their line of arms. This truly is as advertised and for a price that cant be beat. This rifle comes with a great stock and grip and clean, although I field stripped and cleaned mine out of the box which is a good thing to do. Buds was fast and painless on the shipping. I love the payment options too. This was my first purchase through Budsgunshop.com and I will most definitely continue to purchase from them. I cant wait for Spring to hit the range.

    Great rifle! I have nothing, but great experiences with this firearm. I bought this once prices for AR-15 style rifles came down, and the best deal I've seen yet for the SR-556 has been on Buds. This rifle is very accurate. It is slightly heavier than most ar's due to the piston system and heavier barrel, but that only seems to help control recoil and improve accuracy. The rifle is very sturdy and clean in appearance. The whole package is quite nice; the rifle itself, the quad-rail, flip up sights, rail guards, soft case, lock, and three pmags. Mine did come with only one vs three pmags, but after sending a quick email to ruger, 2 new pmags and an additional soft case were sent immediately. I have nothing, but praise for this rifle. Highly recommend it! It may be a bit pricier than other ar's, but you get what you pay for and you're getting very high quality with this piece.

    Great gun! Picked the Ruger up today and immediately took it to the firing range. Put 100 rounds through it using 4 different brands with no malfunctions of any kind. This was my first purchase from Buds and although I was a little skeptical at first, all can say is that this purchase was a pleasure. Buds kept me informed from the start and every step along the way. I didn't expect that. I am looking forward to my next purchase from Buds.
