Build history on GunPartPicker
Builders on GunPartPicker first added the SIG Sauer RM400SDI16BR5FX M400 SDI 556 Black Tele to a build in April 2026.
Availability is good: it was in stock at one retailer or another nearly every day in September 2026, and today 5 of the 7 retailers we track have it in stock. It dipped to $1,437.51 at BattleHawk Armory for a stretch in September 2026, well under its usual $1,749.99, so sales do come around. Buying today, the lowest price is $1,749.99 at Palmetto State Armory, above September's low of $1,437.51, so a better deal may come back.
