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

Just received my rifle Friday the 23rd from Buds. Outstanding! I am a Sig fanatic from way back and I can say this is the best Rifle ever. the light weight and handling is excellent and as a LEO that is important! This is my second buy from Buds and I would give them, their service and this Sig rifle FIVE STARS. LH

I was hoping for a better rifle for $1200 dollars compared to a 600$ ar15 but I didnt get it.
horrible trigger, long and it seems a 10'lb trigger pull. Accuracy is not bad but not noteworthy. My clone ar's would run circles over this one.

nice looking gun but I think they nickel and dime you on the scratched up magazine they fit with the rifle. I purchased three 223 rifle simultaneously for me, my son and my daughter. The sig was for me, the Core15 was for my son and an M&P 15 was my daughters. We used 4 different kinds of ammo up to the cheapest Russian ammo you can get and the Sig won't cycle the Tulammo. The M&P 15 however was taking anything you put in. Bottom line was I got beat by a rifle I paid half off what I paid for mine. Accuracy at up to 45 yards they all shot a group of an inch or less at the bench rest. Save your money unless you are really a Sig fan.
