I have just started dealing with Buds not too long ago and their customer service and professionalism is nothing like I have experienced around here ! simply EXCELLENT !!!!!!!!!!!!

so far I have shot about 800-900 rounds with the 556 xi and if I had to do it all over again I would buy the same gun again, it so far has worked flawless, accurate , shots amazingly well. The built quality is excellent and the gun feels great .... very easy to disassemble and clean. I will be buying the Russian version of this very same gun ........

I purchased this rifle about a year ago from Bud's, using the layaway program. I have to say, that layaway program is pretty great. Anyway, I got the gun in and had it transferred over, everything was fine. I took it home, unboxed it, and inspected it thoroughly. First thing I noticed right off the bat was the large crack in the stock, hidden under the cheek guard. It looks like the rifle was either dropped somewhere along the way, or they had a damaged stock and just said screw it and put it on the rifle anyway. I don't really care, it's just a crack and doesn't seem to be enough to warrant a replacement stock or anything like that. I just found it odd that the entire rifle came in pristine, and I mean right out of the factory pristine, condition and I take this plastic piece off and there's a huge crack. Oh well.

The rifle shoots pretty darn well. As stated in other reviews, it doesn't like Tula very much. Had two light strikes the first time I took it out to shoot. I blame the ammo, not the rifle. Tula is known for having crappy primers. It went through Remington like it was going out of fashion, no hang ups, no misfires, no cycling issues.

Not a bad choice for a mid-range rifle. It's no SCAR-16, but you're not going to have to take out a second mortgage to afford it. It just feels... like quality. Except for the cracked stock, which I would probably replace with a Magpul extending folder or something anyway, I am very, very happy with this as my first rifle. Bud's got it to me quickly (a week or so to my local FFL), and it was in good shape. Love it.

Fantastic rifle. I have no complaints whatsoever on the function and accuracy of this rifle. I do however have a problem with the stock mag. I have had at least one FTL on every instance using the aluminium stock mag, packed with between 6 - 30 rounds. However, my PMags and others operate flawlessly.

Other than the stock mag issue, everything on this gun is very sound and great value for the price. Please ignore the bad reviews about heavy trigger pull. The rifle intentionally operates on a two stage trigger, and some folks just can't fathom that concept.

This Sig 556XI is Absolutely AWESOME!!!!! Great trigger action very crisp. Love the feel of the rifle couldn't be happier with it. Accurate right out of the box didn't get to shoot it that much but what I did ,its a great rifle And as always Buds was great to work with. Can't wait to get the optional barrel for the 762x39mm if your looking for a great AR that is very versatile this is the one. Thanks buds
