    I really enjoy this rifle! I have put about 400 rounds through it, and it just tears holes in the paper at 100-200 yards. The piston-driven system, paired with chrome plated components keeps cleaning easy. It is well worth the price tag for the ideal AR setup.

    I just picked it up yesterday and have not had the chance to fire it, but this Ruger SR-556FB is a real beauty! This thing is built like a TANK, and happily knowing and owning various Ruger products over the years, along with the many positive reviews, I can only expect that we will have many happy years together!

    I am very happy with the firearm from a performance standpoint, as well as all the accessories that come standard. I will have to investigate, possibly with Ruger's assistance, the functionality of the BUIS. To sight the rifle in, at 25 yards the sights require full windage right. After firing approx 300 rounds downrange in training scenarios, I didn't have one malfunction, and the receiver end of the firearm is still clean (one reason I chose a gas piston version). I would purchase this firearm again, and always recommend Buds Gun Shop to my friends.

    The SR-556 arrived in perfect condition, its not nearly as heavy as some people make it out to be either. Overall great gun, my only complaint, is that when i received my SR, the bolt carrier wasn't actually the shiny chrome you see in the pictures and videos, however its not black like the ones that come on the ''E'' model either, (or used to). I will have to contact Ruger and see if they made a mistake or if they are coating their bolt carriers now with a very light grayish paint. for reference this is the FB model 5902. It came with 3 30round pmags and all of the troy industries goodies as well. Like i said before great gun, i would still purchase it again in a heartbeat.

    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 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.
