Description

The M400 DH3 was developed over the course of 2 years, with much input given by Team Sig’s 3-Gun Champion Daniel Horner to create the ultimate competition rifle. This high-performance firearm is outfitted with the unique DH3 stock, which can be finely tuned to the user’s preferred length of pull, cant, and buttpad position. This level of adjustability allows the user to position their eye directly behind the optic, and a foam pad around the buffer tube provides a comfortable cheek weld even on cold days. All of the M400 DH3’s controls are ambidextrous, including the charging handle, safety selector, bolt release, and magazine release to accommodate both left and right-handed shooters. To ensure supreme accuracy, the M400 DH3 features a 16-inch free-floating, match-grade, fluted barrel, which is topped with a 3-chamber compensator which virtually eliminates recoil and greatly reduces muzzle rise. Accuracy is enhanced even further thanks to a 2-stage Timney Trigger that can be adjusted between 2 to 4 lbs. In addition, the M400 DH3 is outfitted with a low profile 3-gun handguard with multiple M-LOK attachment points, allowing the user to tap into the vast aftermarket of M-LOK accessories.

I do not like the foam on the recoil tube. The charging handle catches on it. I have called Sig several times to ask about possible alternatives. I will probably replace the stock with a Magpul Lite stock. I think this was a glaring oversight by SigSauer.
