Umm, it’s pretty ridiculous how good it is

Review by Martin on 13 May 2025 review stating Umm, it’s pretty ridiculous how good it is
This trigger is awesome.

I’ve flirted with springs, honing, filing, and polishing mil spec triggers, even take up set screws that could result in triggers that don’t reset if not tensioned properly.

I’ve installed Geissele triggers, rise armament triggers on AR’s. Franklin triggers on mp5 clones, Apex triggers on Sig pistols. On and on and on.

This triggertech drop in trigger for AR’s is only bested by the triggertech in my 2020 Waypoint. Supremely excellent.

Game changer

Review by Michael W. on 13 May 2025 review stating Game changer
These “handstops” are great. I’m in the process of putting them on every build i have, and unless something better comes along, they will be on every build going forward

Staccato did it AGAIN!

Review by Sgt O. on 13 May 2025 review stating Staccato did it AGAIN!
What can you say! I have 6 already! And I have only owned my XC for a few months!! They are flat out amazing! (Don’t listen to negative reviews just because someone ordered a larger mag than they meant too) - I’m giving this a rating on how it actually performs! And it’s 5 stars- because it’s the flawless feed performance, and super quick connection. both of which a shooter/competitor/& a warfighter demand!

REAL Perfection is not CHEAP, Nor is it POLYMER!

Review by Sgt. O. on 13 May 2025 review stating REAL Perfection is not CHEAP, Nor is it POLYMER!
Lightning speed, YET with EVERY double tap round drill being “key-holed” -Please let me just admit right now! I’m a Marine Infantry NCO, and this UNBELIEVABLE pistol configuration (WITHOUT ANY QUESTION) actually and truly MAKES me a way more accurate, confident, and proficient side arm shooter!! That’s the most honest and humble way I can explain this superior pistol!! It honestly CHANGED my entire situation, and took away the single weakest piece of my overall “tactical proficiency”
and, Ohh yeah, for those that like to be envied …. . whether at the range, or on job… you WILL BE!!!…. That I assure you!
But for the most honest of reasons, not just because it’s as fast and double tap accurate, as a USPSA Race gun. But because I want my back up to always fire and be as accurate as possible!

Last word to sum this freaking nail driver up! BUTTER!!! 🧈
A real single finger🧈action smooth Slide!!! (That should explain enough to those who are extremely tired of industry standards!!

Now I am as accurate with my side arm as all of my “other” tactical platforms! Complete bliss! And worth more if you ask me! For the kind of total tactical safe mindedness it now provides me!

Thank You Staccato!!! I Love your company! And Rainer for making it so fast and easy to get my 1st baby to me!

Bang for buck

Review by Jamie on 12 May 2025 review stating Bang for buck
Bought this upper for my son, he adores this rifle. Mated to an M4 lower with an ACOG on top, this is a top notch upper with all the bells and whistles
