Installation was easy, and trigger pull lighter than expected. I haven't taken it to the range yet, but this will be the third spring kit I installed from MCARBO so I expect it to be excellent like the others were. Overall it was about a 2 3/4 lb reduction in trigger pull weight.
Trigger spring was exactly what I needed. So much lighter trigger than factory. Installation video was very helpful!
Super easy to install, less than 5 minutes. Incredible smooth and light trigger pull. Reduced grouping at 100 yards from basketball to softball.
Excellent product, it reduced my trigger pull by 1.4 lbs.
Easy installation, low cost and fast shipping.
If you own an AR you needed this upgrade.
Went from 6 lb to 4 lb trigger pull. I got the results and the quality I was hoping for. The block of instruction on how to install the product was outstanding. I’m very happy with my purchase of Mcarbo products.
For the money this thing made a big difference. Blackout pistol for my kids to hunt with and this lightened the trigger significantly for them so that they are jerking the trigger.
Easy install and considerable less pull on spring. Works great on 223 ammo, flawless. Haven't tried it with 556 ammo, but hope to very soon next time a range. Video they have available was also great help.
Easy installation and much improved trigger. Need I say more?
