// Why it
The numbers are identical. The record is not.
01 Safety certified by Crane
The SSA® is safety certified by Crane Naval Surface Warfare Center. That is a certification of the trigger, not an endorsement of Second of Ten or any rifle.
02 Laser marked and lot traceable
Every part carries its markings, so the trigger in your rifle can be traced back to its production lot.
03 Inspected per part, not spot-checked
Magnetic particle inspection runs on each part, where the G2S® is spot-checked.
04 Honest about the shooting
Same steel, same sears, same published weights as the G2S®. If it’s a personal carbine and you don’t need the record, the G2S® is the better buy.
// Before you order
Not approved for AR-9 or other pistol-caliber AR builds. None of our triggers — LaRue or Geissele — is approved for an AR-9 or a pistol-caliber upper. Geissele also excludes the SIG MPX/MCX, and fitting one in either voids Geissele’s warranty. Our lowers are rollmarked CAL: MULTI — if a pistol-caliber upper is on the plan, tell us before we fit a trigger.
WARNING: This product can expose you to chemicals including lead, which is known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov.
We don’t stone, polish or modify sear surfaces. Every trigger goes in exactly as its maker built it, keeps the maker’s warranty in full, and is function checked by us. If you want a lighter break, the answer is a different trigger — not a modified one.
Warranty: the maker’s warranty applies in full to an unmodified trigger; we warrant our own fitting and function check. See warranty information.
