Sig Sauer RM400SDI16BP M400 X-Series 5.56x45mm 30+1 16″ Black FNC Chrome Moly Steel Barrel, Black Anodized Aluminum Receiver, 15″ M-LOK Handguard, Synthetic Magpul SL-K Stock, Black Polymer Grip

Description

The Sig Sauer M400 is a semi-auto in .223 REM/5.56 NATO with a 16" barrel, a 1:7 twist and 30-round capacity.

A carbine-length barrel keeps the firearm maneuverable, trading some velocity for handling. That is the standard twist for this cartridge, and it stabilizes the bullet weights most factory ammunition is loaded with. It ships without iron sights, so budget for an optic, rings and a base if you do not already have them.

The .223 REM is commonly chosen for varmints, predators and target work. Cheap, widely available and light on recoil, which makes it an easy cartridge to shoot well.

Please note this item cannot be shipped directly to California, Rhode Island and Washington. Restrictions come from the manufacturer or distributor and are applied automatically at checkout, so check before ordering if you are in one of those states.
