Ruger SR-556 5902 Complete Specs and Full Gun Specifications

Love this gun. A bit on the heavy side but looks awesome and shoots perfectly!

Had such high hopes for this rifle. Terrible accuracy. Tried Multiple types of ammunition and could not get better than 2.5 inch groups at 50 and 100 yards. Worked flawlessly but horrendous accuracy. Not a sniper or professional marksman but I was a Forwa

The Ruger M556 might be a good shooter, but I will never know. When I received this rifle and discovered you could not remove the barrel shroud foregrip without gunsmith tools, I dumped this gun like a hot potato. This is a major design flaw in my mind. A

Thanks, Buds Gunshop another awesome gun I just purchased. Firearm is awesome & great price, can't wait to take it out to the range.

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 s

received my rifle yesterday and have not shot it yet but it arrived in great shap and is one stout AR and will enjoy many years of shooting and this is my second purchase form Buds this year and it was flawless thanks again Buds!

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

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 r

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 vi

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 co

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 mos

Needs a better trigger but other than that best purchase iv'e ever made.

when I got this rifle it came with magpul trigger guard and Samson BUIS w/c look alot better from troy .. As always good service and fast delivery.

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

I have learned to depend on Buds. Ordered a hard to find Ruger SR-556 on Thursday, and tonight (Tuesday) it is in my hands. Thx Buds! Great job!

Managed to get mine before the prices started to climb, and finally got it out to the range this past weekend. Put 300 rounds of Federal 55-gr FMJ through it, and even with my old guy eyesight using the Troy iron sights, this weapon still put rounds withi

Awesome American made AR. Built like a tank. Full rail system, Troy rail covers, and Troy flip battle sights create an awesome package. Upper and lower fit tight, absolutely no rattle as seen with lower end ARs. Great investment.

Fine shooting firearm. Put about 500 rds through it without a hitch. A bit heavy, but that is how Ruger builds guns -like a tank!

This is a fantastic AR-15. Shot about 500 rounds of mixed ammo. It chews through everything with zero problems and was spot on out of the box at 50 yards.

This is a very accurate AR. My only criticism is the trigger action was very heavy. I replaced it with a match 3.5 lb trigger. The Ruger SR-556 it's a tack driver with consistent sub-MOA groupings. I've gone 1000 rounds so far with no FTF or FTE issues, a

This rifle was everything I expected and more, and buds prices where much lower than anywhere around where I live. keep in mind I did a LOT of homework on this firearm and although a bit heaver than a lot of ar style rifles I found that for all that comes

Ruger at it's best... agood solid rifle

Excellent shooting wepon! Alittle on the nose heavy side, but that's the trade off for piston vs. DI. About 100 rounds through it and the bore/bolt is clean as can be.

This was my first AR style rifle. I am very impressed with the total overall package from magazines to rifle to the tactical bag. This thing has everything. The rifle operates flawlessly and is very easy to clean with the piston operation system. Buds was

Just completed my first purchase from Bud's. I am very impressed. Ordered my rifle on Friday and my FFL received it the following Wed. I received several emails tracking it's progress along the way. I can't imagine how the transaction could have been any

Beautiful AR. Only had a chance to get 4 mags through it so far, but didn't have a single problem. Upper and lower fit together very tightly, with no play or wobble at all. The quad rail, quad rail covers, flip up sights and hoage grip are great bonuses t

This was my first firearm purchase from Buds. The price for the Ruger SR556FB was far less than what I would have paid locally, even without the cash discount price. Shipping was exceptionally slow considering I ordered with a credit card on Sunday and th

First time shopping here at buds, customer service was excellent. They kept me up to date through the whole process and the sales staff was more than knowledgeable on any question I had. I ordered it on a tuesday night and received it in exactly one week.

Super Pistol and Service from Bud's as usual. emailed Buds to ask for expedited shipping, two days later it was here. This rifle is top of the line as is Buds costumer service and everything else. Another excellent transaction from Buds!!!

Great gun at 100yd its dead on once you sight it in and at 25yd you can keep a good tight group about 1 to 2 in' grouping even with cheap ammo. I've put only about 300 rounds in it... but I also just got it 3 days ago. Love it so far great shooting gun ju

This is a perfect rifle. When you pick this rifle up it feels so good in your hands, perfect in its handling and shooting. It shoots great and no problem shooting all ammo. Buds has the best price and delivery. I know it seems a little pricy but you get w

1st and foremost its a RUGER, AMERICAN MADE 100% QUALITY!! As an Infantry Marine, ive fired all types of AR platforms, and in my opinion this is hands down #1 out of all of them. The 2 stage chrome plated piston driven operating system is smooth as hell.
