Sig Sauer M400 Enhanced

The Sig M400 Series Enhanced rifle is designed for use in law enforcement, military operations, the sporting field, as well as competitive shooting. The SIG M400 is a true AR platform tactical rifle with unparalleled accuracy. A 16" chrome-lined and phosphate coated barrel provides superior corrosion resistance, and a 7075-T6 aircraft grade aluminum forged lower receiver adds to the durability and reliability that users come to expect from Sig Sauer.

I have 4 AR15s and this is by far my favorite. I've had it for over a year now and it's never failed me. I would stack this Sig Sauer M400 Enhanced against any other AR on the market today.

I was looking for a Sig Sauer M400 Enhanced and I found this one on Amazon. I was a little skeptical at first because of the price, but it came with all the features that I wanted and more. The quality is top notch and it's been working great so far.

I was looking for a new rifle and I came across the Sig Sauer M400 Enhanced. I had never heard of it before but it looked like a great gun. I did some research and found out that it's one of the best rifles in the market today. It's got a great weight, is accurate, and has a nice feel to it.

I've been shooting for a while now and I can't believe how much better the SIG M400 is. It's so much more accurate, has a better grip, and is just overall more comfortable to shoot. I'm really happy with my purchase!

I am a gun enthusiast and I have to say that this is one of the best guns I have ever owned. It's accurate, has a nice weight to it, and shoots really nicely. The only downside is that it's expensive but if you're looking for a high-quality gun then this is the one for you!

I am a huge fan of Magpul and have been using their products for years. I was really excited to see that they are now making furniture and sights for Sig Sauer M400 Enhanced. The furniture is very durable and the sight is easy to use. I would highly recommend this product!
