Does it really? I’m not familiar with the Trooper, but when I looked it up earlier the image I saw did not have one.

You are correct. The Trooper has a 13" MLOK rail. I'll edit my post.

Pros: Both great rifles. The Colt will probably hold it's value better.

The Colt comes w/ a 13" handguard and free floated barrel.

The Sig M400 has a 15" handguard and free floated barrel. It also has a spring loaded detent under the rear lug to keep the upper/lower fit tight.

Cons: Colt has a M4 style buttstock.

The retail M400 does not come with any flip-up sights (the first responder variant called the PRO comes w/ steel flip-up sights, a QD sling, and QD rail piece).

Looks like Colt ships without sights too.

Decision? Get the one that makes you happy!
