I bought one before and liked it so I bought another one for my other AR. They are great so buy one or two, you will like it also.
Worked as advertised and very easy to install. With this modification my trigger pull weight went from 7+ pounds to less than 4.5.
This spring plus the set screw trick reduced my trigger from 6 pounds to 3.75 pounds! Could not be more pleased!
Yes itbis all as advertised, so do not hesitate, get yours today!!! It was easy to put in, easy to see the difference, and with lifetime warranty...who could complain...not ME!! On way to range...bye!!
Work great for 300 blk pistol build. trigger breaks a clean 4lb for me. Thanks mcrabo!
I had 2 mil-spec LPK's installed in my lowers. I have drop in triggers but am going to Front Site for a course and needed to be over 4# trigger pull. The drop in's could not be adjusted that high, (that's why you buy them :-), so I just installed mil-spec for the trip. One was a PSA which averaged 6.25# and one an Anderson which averaged 7.5#, HORRIBLE even after polishing and buffing them! I have used other Mcarbo trigger upgrades in other guns to my satisfaction so I thought I would try it. PSA went down to a little under 5# and the Anderson ended up at 5.25#. Much better. I would like to get them closer to 4# but don't want to fail inspection either. Will ALWAYS consider M-Carbo parts for future products!
This was easy to install and helped me to get tight groups with my Ruger AR556!!! I could not believe the results. Thanks again!!
Got 2 of these. Installed in 1 of the 2 and the other will come soon when other parts come in. Feel great so far. Will shoot this weekend to confirm, but cant argue so far!
Installed the spring and went to the range immediately afterwards. Worked flawlessly with 3 different manufacturers ammo and my own reloads. Excellent product!! It was put in an Andersen lower and getting couple more for my Aero Precision pistol and my Spikes lower.
Lowered trigger pull weight a solid 2 lbs each on our 2 AR's . Easy to install. Happy with product. Very fair price. Shipping is fast.
The spring works as described. Very easy installation
Shipping was fast and installation is easy. Night and day feeling after installing.
Super easy to install, less than 5 minutes. Incredible smooth and light trigger pull. Reduced grouping at 100 yards from basketball to softball.
Made an inexpensive AR feel like a million bucks. Excellent product. Thank you again.
The spring looks different than a standard spring but fits perfectly. I tested the original spring at 5.5 lbs and after I installed the new spring I got 4.25 lbs and the trigger is so much smoother now. I have tried many other springs but got nothing this close. Awesome buy.
After purchasing the MCARBO 590A1 trigger kit, my confidence was already high to see what MCARBO cooked up for the AR-15. Installation took minutes. My primary intention was to smooth out the trigger of the AR, with a secondary on a lighter trigger pull; I received both. I do not have a trigger pull gauge but it was very apparent that the trigger is smoother and lighter. Also, the shipping, what am I talking about shipping. It was more like it was beamed to my house. Unbelievably fast. Like I said you will not be disappointed with this product. The cost effectiveness, ease of install, and performance make this a must for any gritty, heavy, stock trigger.
