The 20 in heavy stainless barrel uses 5/8-24 tapered-shoulder threads and ships with a factory three-prong QD flash hider. A 1:10 twist rate is optimized for common .308 Win bullet weights, and the free-float M-LOK aluminum handguard maintains barrel clearance while offering accessory mounting options.
A three-lug bolt with a 60° throw delivers fast cycling and plenty of scope clearance, while the two-stage, adjustable match trigger supports precise shot control. The rifle feeds from AICS-pattern magazines and has a 10+1 capacity.
The folding stock shortens the rifle for storage and transport, and includes an adjustable cheekpiece, adjustable buttpad, QD sling socket, and a skeletonized design. Length of pull is set at 13.0 in, with approximate overall lengths of 41.8 in extended, 39.8 in collapsed, and 30.9 in folded.
A full-length 20-MOA Picatinny top rail bridges the receiver and handguard for robust, continuous mounting space. The aluminum receiver features a black anodized finish to match the rifle’s overall black colorway, and the package weighs about 7.7 lb. Made in the USA; Mfg Part No. CROSS-308-20B-STX.
