Most Helpful Positive Review Shoots perfect controlled pairs
I have yet to do a mag dump, because ammo is so expensive but the double taps are amazingly accurate. Much better than a 3 round burst in my opinion (4 years in the ARMY.) IF YOU'RE INTO full auto go with the echo, if you want controlled pairs, then by all means pick the cheaper route. I purchase...

Most Helpful Negative Review Don’t waste your money
Installed the trigger straight from Franklin Armory and would not pass first function test. Contacted manufacturer and they told me to try a different lower and hammer, 3 lowers and 4 hammers later, still wouldn’t function properly. After having to pay for my own shipping to return it, the manufactu...

over priced garbage

by C.T., Verified Owner from LA, United States Written on July 17, 2025
Seen this on YouTube all positive videos, and thought it was pretty cool. I ordered it and like always it was out of stock so had to wait quite a bit continued watching videos on YouTube all of a sudden everything was showing how much garbage this is tried to cancel but miraculously shipped the day. I made that phone call received it about two days later was pretty easy to install. My first shot was with a 22 conversion kit installed fired 10 rounds. Everything was great. I was happy as could be put my BCG back into the rifle and ran 7556 had a few hiccups. tried the springs that come with it found my OEM buffer spray worked best, but it’s too easy to out run. The trigger have tried multiple springs and buffer weights from carbine H one and H2 with same issue of out running the trigger and getting a hang up, can quickly recycle and get back in to action, but not ideal. Also after I placed my order, I did some checking around and found it for $125 less at Palmetto State armory Optics Planet really stuck it to me on this order but that’s on May for not shopping around first but overall the trigger is not for anything other than goofing around would not put that in any thing else than a range toy at the end of the day would never make this purchase again
Pros:
  • None
Cons:
  • WAY Over Priced
Best Used for:
  • Throwing
Would recommend: No

Not for ANY serious rifle platform...More of a novelty than anything else

by Dave, from MA, United States Written on June 9, 2025
I have high end triggers in all my "serious" rifle platforms. As an former armorer in the military maintianing/shooting military small arms, and shooting rifles / pistolas for 40+ years. Binary aside, this is by far the worst trigger "feel" of any I have ever used....Lots of creep and very gritty and not predictable. It's not a one or even a two stage. I have no idea what catagory to put this in. The cam rocking internals before it breaks is part of the problem so just doing a "trigger job" on a $350.00 trigger will not fix it. IMOiIt should be in toy plastic rifle, its about the same feel. I'll take it out for a dance since it's in the lower, and then sell it. And then install a Geissele trigger.
Pros:
  • Binary
Cons:
  • The whole trigger system
Best Used for:
  • Novelty / Not Serious Rifle Platform
Would recommend: No

Go with fostech

by Dan, Verified Owner from OH, United States Written on February 22, 2025
Go with the fostech. Not only is it a drop-in, but it works in all receivers. The issue you may have is with steel case ammo for that they sale an enhanced spring. You may also have to buy an enhanced firing pin for 7.62x39
