Description
The Geissele Hi-Speed National Match is the adjustable trigger in the Geissele line. It is a two-stage AR-15 trigger where you can tune first stage weight, second stage weight, and overtravel. This set ships with all three spring sets, Service Rifle, DMR, and Match Rifle, so one trigger covers everything from a 4.5 lb NRA-legal pull down to a sub 2 lb match pull.
Per Geissele, the Service Rifle springs give a 3.2 to 5 lb first stage and 0.5 to 1.5 lb second stage for a 4.5 lb minimum total. DMR springs run 2.5 to 3.6 lb first stage for a 3 to 5.1 lb total. Match Rifle springs go down to a 1.5 to 2.5 lb first stage and a 6 to 14 oz second stage, for 1.9 to 3.4 lb total. It fits mil-spec AR-15 and AR-10 lowers with .154 in pins and uses a curved bow. Adjusting it means pulling the trigger group and working set screws, so plan on some bench time to dial it in.
Heads up: This is a precision tool, not a drop-and-forget trigger. If you do not want to tune springs and screws, an SSA-E or SD-E gets you a fixed light pull with zero setup.

Who it’s for
High Power and Service Rifle competitors, precision gas gun shooters, and 3-Gunners who shoot a lot of long-range rifle and want to set an exact pull weight. Also anyone who wants to try three pull weights before committing.
Who should skip it
If your rifle is a do-everything carbine or you run close, fast stages, a non-adjustable SSA-E, SD-E, or S3G is simpler and cheaper. Skip it if you have no interest in tuning set screws, since a poorly adjusted Hi-Speed can double or fail to reset.
