The Siete’s right-hand bolt uses a large round knob for positive manipulation, and the bolt-action system is paired with a 17 in match-grade barrel that is both threaded and quick-change capable. A free-float M-LOK aluminum handguard and T-marked Picatinny top rails on the receiver and handguard provide mounting space fore and aft; the clamp/lever housing at the junction is non-slotted and does not allow continuous mounting across the joint.
Designed around takedown and fast barrel swaps, the rifle employs a switch-barrel, torque-indexed system with a tool-less side clamp/lever for retention. Identifying marks include a receiver marked "Siete," a barrel ring engraved "LaRue SIETE - S/A," and "308W" visible through the handguard’s caliber window. Stated capacity is 5+1 with AICS-pattern magazines.
The modified LaRue RAT stock folds and mounts to a 6-position receiver extension with numeric position marks and a cheek riser, allowing a length of pull of 12.75 in. Controls and furniture include a Timney single-stage trigger at approximately 2.5 lb and a LaRue A-PEG pistol grip.
Construction emphasizes durability and precision with an aluminum receiver and handguard. The buttstock housing is marked "GSA CONTRACT GS-07F-5784P" and "CAGE CODE 0B6B5." Manufactured by LaRue Tactical in Leander, Texas, USA, this Siete arrives with a LaRue QD bipod adapter installed, a spring-tension bipod, and a one-piece scope mount, all housed in a factory briefcase-style hard case to complement its takedown intent.
