Re: trigger upgrade for TAC 15i
The short answer to the question is Yes!
The Timney AR15 Trigger is one of the simplest high quality trigger available for an AR15 (TAC15/15i) crossbow.
Many trigger replacements for these crossbows will require some gunsmithing knowledge and work, but the Timney requires nothing other than a couple very basic tools and about 30 minutes start to finish.
Len and Andy sell them at standard manufactures pricing in the LRH Store on this website.
