SA JET-01 Chassis — Folding, Competition-Grade Chassis for SSG3000 & 200 STR
A balanced, folding aluminium chassis engineered for SIG SAUER SSG3000 and 200 STR. Tool-less fit, clean interfaces, and repeatable ergonomics for precision on the bench, tripod, or in the field.
What it is
• A 6 mrad (20 MOA) Picatinny top rail accessory for the JET-01 chassis.
• Provides forward cant so you retain more elevation travel for long-range dialing.
• Aligns inline clip-ons (night/thermal) while keeping sightlines consistent.
Why it matters
• Extends usable elevation without maxing the turret at distance.
• Keeps your optical stack square and repeatable between day and night setups.
• Simple, rigid interface that’s easy to reinstall to marked slots/torque.
Setup & fit
• Degrease, seat the rail, and tighten evenly to your recorded torque spec.
• Level the optic to the bore line after installation; confirm in position with a visible bubble.
• Witness-mark screws for quick visual checks after travel.
Use cases
• Long-range zero where you want mid-travel dialing headroom.
• Clip-on devices that require a true, repeatable Picatinny datum.
• Match prep: standardize the same slot positions so return-to-zero is predictable.
Tips for consistency
• Record final zero, turret position, and rail slot placement on a setup card.
• Reconfirm zero after major temperature swings or accessory changes.
• Don’t over-torque rings/bases—crushed interfaces wander under recoil.
