Introducing the MTA™ — Modular Trigger Assembly™

Luth-AR MTA™ Trigger

High quality AR-15 drop-in trigger.

When it comes to a performance trigger in an AR platform you have two choices, find a qualified gunsmith and pay them to perform a custom trigger job from stock trigger parts, or simply drop-in a Luth-AR MTA™ trigger ready to go. The MTA™ housing is made from 6061 Hardcoat Anodized Aluminum. The internals are precision cut from EDM process using A2 tool steel and heat treated to 40-45 HRC and utilize SST bushings and springs resulting in a crisp 3 1/2 lb trigger break.
