The M400-TREAD V2 COIL brings a factory-built, range-ready mentality to the platform-no guessing or bolt-on shopping required. Purpose-fit upgrades like the ROMEO5 Gen II compact red dot, installed M-LOK vertical foregrip, and barricade stop arrive pre-installed and optimized to work with the enhanced free-floating TREAD handguard. The 16" stainless barrel with a 1:8 twist and mid-length gas system delivers smooth, predictable cycling and controllable recoil; paired with the SIG 2-stage Matchlite DUO trigger and Magpul SL-K stock it's setup for accurate, comfortable follow-up shots right out of the box.Specifications:SKU: RM400-16B-TRD-V2-COILCaliber: 5.56 NATOSights: ROMEO5 Gen II compact red dot (installed)Barrel Length: 16 in (406.4 mm) stainless steelTwist Rate: 1:8Threads: 1/2"-28 tpi tapered shoulderMuzzle Device: SIG 3-prong flash hider (installed)Action Type: Semi-AutoOperating System: Mid-length direct impingementStock: 6-position Magpul SL-KGrip: Reduced angle polymer pistol gripTrigger: SIG 2-Stage Matchlite DUO (flat shoe)Manual Safety: AmbidextrousForend: Tread Enhanced M-LOK black alloy (free-floating)Accessory Rail: M-LOKMagazine Type: AR-15 (1) 30-rd polymer mag includedReceiver Finish: Black anodizedOverall Length: 32.5 inCollapsed / Folded Length: N/AOverall Width: 2.6 inHeight: 9.25 in (with optic installed)Weight: 7.0 lbAdjustable Gas System: No (mid-length piston/DI specified as direct impingement mid-length)Included Accessories: ROMEO5 Gen II, M-LOK vertical foregrip, barricade stop, (1) 30rd mag
