Great gun. I was busting water bottles at a 100 yards after three shots. I added a quad rail and a pistol grip before taking it out. Great setup. Simple, efficient, and accurate. It took a while to get it due to some processing delays but all in all I'm satisfied.

Extremely accurate and all you would expect from a Sig Sauer!

This was my third purchase from buds and by far my favorite. The weapon performs flawlessly every time I squeeze the trigger. Sig deserves some major respect for building a weapon that performs as well as my buddys bcm. I have added a six power scope, a larger latch on the charging handle and a muculek compensator. Thanks bud!

EEHa, Ok frist off had this gun a little while so I have put over 2,000 rounds through it. Pretty easy when I am on several hundred acers in a county in New Mexico that lets people have their own responsible fun. I am using the magpro 30 round without any problems. Tried a couple diffrent scopes at over 100yards and kept a tight grouping for my level of shooting at 150 to 200 yards, and lots of time just iron sight, from about 50 yards. Zero problems and with time I am expecting a tighter grouping. I do not plan to add anything to it I already have a two toys already tricked out, and going to keep this one pretty origional. A few guys from work are talking about coming out to give it try. Looks like it is time to break out the backhoe and do some serious digging for incressed safty.

Finally, a chance to fire thus sweet rifle. I just ran about 300 rounds of some pretty inexpensive rounds. I had a good time with the wife shooting. Would recommend. I just want to add some reflex sights.

Arrived in excellent condition cosmetically and functionally. Only been to the range once and put about 200 rounds of PRVI Partizan ammo through it with no malfunctions or anomalies. I would recommend a rubber recoil pad for extended shooting as the textured plastic stock end is grippy and will irritate the shoulder rather rapidly without padding.

Only slightly disappointed, there was a good sized guff in the pistol grip. The good news is, it isn't in a place my fingers rest so by holding it, I don't notice it. That being said, for $1000 i would've expected that not be there. Otherwise, totally awesome gun.

Nothing fancy, simple AR with Sig quality. I know they were slacking with the newer rifles but they went back to the fundamentals on this one. Great gun for the price! Eats through even cheap ammo like nothing. You get a great rifles for a great price. One stinker is they only have 1 year warranty.

Great price great rifle. Just recently purchased again. You can't beat buds prices.

A great AR style rifle for the price. Very solid construction, and mine was rather clean when I received it. Haven't had a chance to take it to the range yet, but will repost when I do. The only negative things that I have to comment about are the pistol grip that comes as standard on the Sig, it feels a little funky and didn't fit my hand right, and I replaced it with a Magpul grip. The other is the steel magazine that came with the gun itself, it was rather beaten up and won't feed right, so I recommend using Magpul's PMAGs, which are of a much greater reliability.

I can't say enough about my satisfaction level with Buds. Fast shipping as always, and the M400 is just what the doctor ordered from Sig.

Okay, fired 300+ rounds on the first rip out and the weapon performed flawless as expected.

This firearm is not of the quality that I expected from Sig Sauer. When the rear takedown pin is removed the weapon has lots play between the forward pin eye on the receiver and the upper receiver. In any case if I would have been able to inspect the rifle at a gun shop I would have gone with the Rock River Arms for another $100.00 dollars. Once I replaced the stock forgrip with a quad rail and attached the Eotech it looks good and the iron sights are still functional. The ajustable rear is okay but of cheap quality, once I replace it with a Magpul all will be fine. Also the pistol grip is junk and must be replaced. It is crappy hard plastic and feels like it will fall right out of your hand. I will install a nice rubber coated grip and all should be fine. BTW Sig Sauer support is excellent, but I still say the RRA is a much better choice than the M400 by Sig. This was Sig's first impingement type true AR platform so I had to try it. I will let you guys know how the weapon performs in a later post. I am certian that it will not dissapoint in that regard.

Haven't shot the rifle yet but it has a solid feel to it no rattleing like other AR's. Really nice quality what is there to say its a Sig.
