sig 556 VS ruger sr-556 vs su-16c

[G27RR]

I have had a 556 SWAT with a Nikon red dot on it for several months now. It has the newer sights, which I like. The Nikon cowitnesses with those sights perfectly and right out of the box it was shooting 1'' four-shot groups at 50 meters with bulk ammo. I was and am very pleased with it. I don't know what all the fuss is about the stock and sights, but it must be primarily about the lower models with the flip up sights. The SWAT model is great. I have also had zero problems with the Sig magazines, although some say they can be a problem. I have a several Magpul AR-15 mags that also work great.

I do agree that it is a bit muzzle heavy. A vertical grip can help some people with that. If I had to choose again, I'd still buy it. I have no experience with the Ruger or SU-16 so can't comment there.

1000k Rounds

(Drifting just a little . . .)

Just musing on how long it would take to shoot 1,000k (1,000,000) rounds through an AR.

Assume four hours a week at the range shooting said AR. Assume hand loading of magazines. Assume one minute to load a 20-round magazine. Assume 2 seconds to load and charge rifle. Assume 2 seconds per aimed shot. Assume a reasonably constant shooting session where one loads a 20-round magazine, shoots using aimed fire, reloads, and so on. For four hours. No coffee or potty breaks. Also assume the rifle requires no cleaning and has no failures.

At one minute per 20-round magazine, it would take 1,000,000 / 20 minutes to load all the rounds. That's 50,000 minutes of loading magazines. That's a further 100,000 seconds to load and charge all the magazines, or 1,667 minutes. Total magazine handling time: 51,667 minutes.

At two seconds per round, aimed fire, that's 2,000,000 seconds, or 33,333 minutes.

So, we're at 51,667 + 33,333 minutes, or 85,000 total, giving 85,000 / 60 = 1,417 hours of range time.

At four hours per week, that's 1,417 / 4 = 354 weeks. At 52 weeks per year, that's 6.8 years. Throw in a little vacation time, and you're at about seven years.

So, if you religiously shot for four hours every week for seven years, using magazines you loaded while at the range, and nothing broke, it would take most of seven years to shoot up a million rounds of ammo. (And we never even got into handling the targets.)

I'm sure you were all just dying to know that.

Speaking strictly as an observer, the AR-15 and AK-47 have a market advantage over their competition due to the much higher sales volume, and the large number of separate manufacturers.

For the AR-15, there the existence of a milspec. I don't mean to say that every AR-15 is milspec, but to survive in the competitive market, every AR-15 has to be nearly milspec. Dealers are going to drop a bad AR-15 manufacturer in a heartbeat because they have plenty of good suppliers. So I believe you are going to get more value (quality per dollar) in an AR-15 than any other similar rifle. I don't think you can make a case for a Mini-14 or SU-16 based on value. (If you want one for its unique features, that's fine, but I don't think it's a better rifle for the money.)

jlott00 no need to apoligize you said 1k in your post avenger29 mistakenly repeated it as 1000k in his.

Again, I offer: no other weapon uses a DI system. All gas-operated rifles before and since use some sort of piston variant.

The Iranians came out with a DI rifle.
I guess you could claim it is a reworked m16 but it is a new design and I doubt it has very many parts that will interchange with an m16, other than the magazine.

great info so far thanks, any other that can comment on the sig's accuracy ?

I'm not a crack shot, I just enjoy shooting. But my groupings with my 556 are pretty tight. Its not a nail driver, its a rack weapon.


Its more than accurate enough to hit and kill a person at any range your going to engage them with a 5.56 carbine.


Ever since I switched to quality mags mine has been 100% reliable. Not one single hickup of anykind in the last 900 rounds I have put through it. Everytime I pull the trigger it goes bang without fail. When I first got mine I had feeding problems with the Sig mags, Pmags fixed this.

I did not mistakenly repeat "1000K". He had "1000K" in his second post. I copied and pasted directly from that post, then put the quote tags around it.

There is variation as to the quality of AR parts, but most of the manufactorers seem to do a pretty good job of keeping the dimensions pretty close to standard. Which allows you to have a rifle, say, a Rock River lower, JP enterprises trigger, Magpul MOE stock, A2 pistol grip, Olympic upper, Bushmaster BCG, and White Oak barrel, and have everything pretty much play nice together.

i could get a mag adapter for a saiga 223 also..for about 430 rifle/adapter

I would advise against ordering a Mongolia State Armory adapter from their website. The adapters were a good product but the owner apparently had some personal problems and he is not living up to his business obligations. There are many people that ordered months ago and have not received their adapters. Their attempts to contact him have gone unanswered and refunds have not been issued.

Various persons are in the process of seeking resolution through the CC companies, pay pal or other legal avenues.

Further MSA has had their business account suspended on the saiga forums for failing to pay and failing to respond to repeated attempts by the administrators of that sight to contact him over the course of 4 moths.

The worst par IMHO is MSA has their sight up and will accept your order still. I would not plan on getting anything you order however. I'm guessing, but the company is probably insolvent as well so recovering if you've ordered might prove difficult. The guy has basically destroyed his business rep and company name, mostly by not communicating with anyone.

Couple off the cuff thoughts:

1. Obviously, your choices are way different price ranges. *IF* you're going to spend enough to get a Sig 556 or the Ruger, then do yourself a favor - I strongly suggest you get the Robinson XCR instead for roughly the same price - better gun, IMO. More modular / versatile, better gas system, and it's an American company. The safety on the Sig is too far forward, and the thing is heavy.

2. Actually NONE of those are truly AR15 style rifles, since by definition, the AR15 is a gas impingement rifle. But obviously the Ruger is a pseudo-AR15 style.

3. I don't like the plastic main rail on the Kel Tec - seems like it would get chewed up over time with rings/mounts. But if the rail holds up, then by most all accounts, this is a good and good shooting rifle.

4. I don't own any of those, but if I had to choose among those, I'd get the Ruger. Or as I said, better yet, a Robinson XCR or maybe wait for the Masada (Remington ACR). Or even a good true AR15 - don't believe the hype - they work great.

It's like I have a crystal ball. A few people responded to me and each described the numerous ways it was the fault of every Soldier in the entire Army and not the weapon, including incorrect guesses (stored and fired "dry dry dry," when the reality is, we took condiment bottles full of CLP to the range and hosed those things down).

As for the "conspiracy" angle, here's the rub: I've only read of these miraculous ARs. I've seen and experienced the opposite and know very few people in real life who wouldn't prefer another rifle to it.

Also, from my crystal ball, I knew I'd learn of some obscure weapons! I see the only one developed since the M16 (all others seem to have entered and left service in the 40s-50s) is the Iranian bullpup. Total count: 5? (Including the MAS - 4x weapons each as different guns). Now let's list piston designs.
