First time trigger replacement - Triggertech AR-15 Diamond Trigger

This was my first time replacing a trigger on my Colt AR15 and I was very pleased with how easy it was. I watched some videos on YouTube and probably the most difficult stage was removing the safety. Be careful to watch for the small pin that holds it in once the pistol grip is removed. Trigger tech directions were easy to follow and the install was a breeze. I’ve seen some posts about needing antiwalk pins but that is unnecessary once the trigger is firmly in place using the supplied hex wrench. I followed all the safety checks in the manual and headed to the range. With one round loaded I checked the safety as instructed then fired a round. Wow! So crisp and fast! I left it at factory settings, I believe 1.5 as opposed to milspec of 5+. It took a few rounds to adjust but then it was so natural. Much easier to get tight groups as you’re not fighting the trigger pull. Fantastic trigger, super easy install!
