Price and stock
The CMMG Barrel Sub-Assembly Heavy Taper 308 Win 18in 416SS was hard to find in September 2026, in stock on only 6 of the 24 days we checked, and today only CMMG has it in stock. It dipped to $238.22 at BattleHawk Armory for a stretch in September 2026, under its usual $264.08, so sales do come around. Buying today, the lowest price is $299.95 at CMMG, above September's low of $238.22, so a better deal may come back.
