Frequently Asked Questions
Sig Sauer M400 tread snakebite for sale
Is the SIG M400 Tread a good AR-15?
The SIG M400 Tread is a solid AR-15 featuring a free-float M-LOK handguard and mil-spec trigger. Reliable and well-built, it suits range shooting and new AR owners. Found for under $800, it sits in the budget category and competes well against similarly priced rifles from Aero Precision or BCM.
What is the price of the SIGM400 tread?
The SIG M400 Tread sells between roughly $909 and $1,009, with an average new price around $1,149. Six retailers currently stock this 5.56 NATO rifle.
What ammo does a SIG Sauer M400 tread use?
The SIG Sauer M400 Tread chambers 5.56x45mm NATO and can also fire .223 Remington. Since 5.56 chambers have slightly more headspace than .223 chambers, shooting .223 in this rifle is safe and generally reliable.
What handguards fit a SIGM400 tread?
Samson SXT-Series M-LOK handguards fit the M400 Tread directly, using the same barrel nut as the factory handguard. The 15-inch SXT model is popular among Tread owners seeking a free-float upgrade with improved ergonomics and attachment points.
Is the SIG M400 tread suppressor ready?
The M400 Tread barrel is threaded 1/2x28, which is the standard pitch for 5.56 NATO suppressors. Remove the factory A2 flash hider and attach a compatible suppressor. Always verify your suppressor's thread pitch matches before installation.
Where is SIG M400 made?
SIG Sauer manufactures the M400 in the United States, primarily at their facilities in Exeter and Newington, New Hampshire.
Is the SIG M400 a pistol or rifle?
SIG M400 comes in both configurations. The rifle version features a longer barrel for range use, while the pistol variant has an 11.5-inch barrel with a carbine-length gas system. Both are direct-impingement AR-15 platforms chambered in 5.56 NATO.
Why is it called a snakebite?
The reason the SIG Sauer M400 Tread "Snakebite" variant carries that name is not publicly documented in available sources. We don't have a confirmed explanation from SIG Sauer for this specific naming choice. Check SIG Sauer's official website or contact their customer support for an authoritative answer.
