Building upon their decades of experience and countless hours of instruction, Sig have developed the M400-SDI X to meet the highest standards of performance and reliability. With fully ambidextrous controls including a bolt catch\/and release unique to the M400-SDI lower-receiver, the M400-SDI X delivers advanced performance for both left \u0026amp; right-handed shooters and makes transitional shooting easier than ever. The free-floating handguard utilizes a steel lockup design that significantly reduces handguard deflection by providing maximum rigidity and allows for accessories to be attached on all four sides with no effect on accuracy. The 2-Stage Matchlite Duo trigger provides an out-of-the-box crisp 4.5 - 6.5lb pull weight with a flat blade design for a precision feel. The M400-SDI X utilizes the highest quality performance coatings to ensure maximum durability and reliability.\n\nKEY FEATURES:\nAmbidextrous Bolt Catch and Release | Low Profile Gas Block with Mid-Length System | SIG 2-Stage Matchlite Duo Trigger | Hybrid Compensator\/Flash Hider | Magpul SL Stock | Flat Dark Earth Cerakote Finish","brand":"Atomic Defense","offers":[{"title":"Flat Dark Earth \/ Cerakote \/ 30 Rounds","offer_id":56740694917425,"sku":"RM400-SDI-16B-FDE","price":1599.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0918\/4680\/3761\/files\/SGRM400-SDI-16B-FDE_1.jpg?v=1791838070","url":"https:\/\/selfrescuetactical.com\/products\/sig-sauer-m400-sdi-semi-automatic-rifle-ar-223-remington-5-56-nato-16-cold-hammer-forged-steel-barrel-cerakote-finish-flat-dark-earth-magpul-sl-stock-sig-2-stage-matchlite-duo-trigger-low-profile-gas-block-with-mid-length-ga","provider":"Self Rescue Tactical ","version":"1.0","type":"link"}
